PSPDFKit Changelog

Newest Release

6.9.3 - 1 Sep 2017

This will be one of the last releases in the PSPDFKit for iOS version 6 branch, while we're busy working on version 7. It includes a fix for using it with Xcode 9, however we still recommend Xcode 8 for compiling and testing.

PSPDFKit 7 for iOS will require Xcode 9 and keep compatibility for iOS 9 until the end of the year to ease the transition. Read more about our version support here: https://pspdfkit.com/guides/ios/current/announcements/version-support/

  To restore the equivalent of PSPDFKit’s previous default behavior (using either a popover or full screen, depending on the space available), set the presented view controller’s modalPresentationStyle to UIModalPresentationPopover.
Changed

The annotation toolbar now automatically adapts its items depending on the available screen real estate. This change comes with a new API that allows setting multiple toolbar configurations amongst which the toolbar picks the optimal layout. (#3950)
Changed
The free text input accessory view has been updated to show popover pickers whenever possible, with a fallback to the half modal inspector, if vertical space is tight. (#3987)
- Changed
  
  Note: We noticed some input accessory view resizing issues on iPad Air 2 Simulator. We could not reproduce the same problems on actual devices.
Changed

We’re using UIAlertController and UISearchController everywhere, replacing the older deprecated API for further view controller unification. (#3381)
Changed

Automatic double page mode is smarter, comparing the aspect ratios of the view and the document and only showing two pages if they fit without too much shrinking. Automatic mode is now the default on iPhone too, but since two pages are only shown in large views the behavior will be similar.
Changed

By default, page thumbnails are now sized adaptively to comfortably fill the available space.
Changed
Instead of CGPDFDataProvider we now have a new PSPDFDataProvider protocol, which finally allows writing as well. (#3690)
- Changed
  
  PSPDFAESCryptoDataProvider has been updated to allow writing annotations back into the secure storage.
Changed

Safari view controller is used instead of PSPDFWebViewController on iOS 9.
Changed

Changed

PSPDFAnnotationStateManager now supports multiple delegates and the delegate protocol gained some new methods. (#3607)
Changed

The color menu is now represented visually, and uses the style manager color presets. (#2802, #2890)
Changed

Switching between regular and callout styles for text annotations now produces better results and has been made easier with a redesigned UI. (#3664 and #3859)
Changed

The annotation stream now gets properly reset when an annotation is modified, preventing stale content from being rendered on screen. (#3817)
Changed

PSPDFDocumentActionExecutor’s presentationController has been renamed to sourceViewController to better describe its purpose and avoid confusion with UIPresentationController.
Changed

The prefersStatusBarHidden property in the PSPDFStyleable protocol has been renamed to forcesStatusBarHidden to be distinct from the closely related UIViewController method of the same name.
Changed

It is now possible to show color presents on PSPDFAnnotationStyleViewController, even if color and opacity settings are disabled. Color presets can still be hidden by adjusting typesShowingColorPresets. (#4108)
Changed

Accessibility and voice over support has been improved on some of our key UI elements. (#3834)
Changed

The author username is now requested earlier and managed via the new PSPDFUsernameHelper class.
Changed

The border radius of PSPDFSearchHighlightView is now dynamically calculated based on the current zoom level and can be configured via cornerRadiusProportion.
Changed

PSPDFImageInfo is now much more reliable and detects more image formats.
Changed

PSPDFActions nextAction is now an array to correctly reflect the PDF spec, and the whole tree is iterated as required upon execution.
Changed

PSPDFRenditionAction now also exposes optional attached javascripts.
Changed

The hooks for markedContentStack and shouldParseCharacter: in the PSPDFTextParser have been removed since they were very rarely used but caused a noticeable slowdown for all text extraction. If there's demand, we'll look into ways to reintroduce a similar feature with less performance impact.
Changed

prefersStatusBarHidden in PSPDFStyleable has been renamed to forcesStatusBarHidden to not confuse this with properties that UIKit recently introduced.
Changed

Several annotation classes have new parent types to unify certain features, such as PSPDFAssetAnnotation and PSPDFAbstractShapeAnnotation.
Changed

Small UI updates across the board. (For example, dark colors are easier to see in menus.)
Changed

Various lesser-used API has been redesigned or removed for better clarity.

This release will be one of our last v4 releases, while v5 for iOS 9/8 is steadily nearing completion with a huge list of updates/improvements. We backported the new bezier path calculation code, so ink annotations are quite a bit faster now. There's a lot more coming soon!

Changed

When invoking search, we now prioritize the current visible pages before searching the rest. Search results will show up significantly faster on complex documents. (Z#1829)
Fixed

Fixes an issue where resetting choice form elements didn't always reset all properties. (Z#1813)

4.4.11 - 31 Jul 2015

Added

Adds Czech, Greek and Finnish translations and updates various other localization details.
API

The rotationLock has been removed. Subclass PSPDFViewController and override the rotation methods and/or implement supportedInterfaceOrientationsForWindow: to lock rotation.

3.6.0 - 16 Mar 2014

We're proud to ship the next milestone of PSPDFKit. Version 3.6 features a completely new annotation toolbar, search within annotation text, note annotations that show up in the thumbnails and countless other improvements. This release has been fully tested with Xcode 5.1 and iOS 7.1. We now require at least Xcode 5.0.2 and SDK 7 to compile and have dropped support for Xcode 4.6 (Apple no longer accepts apps built with SDK 6/Xcode 4.6) Applications built with PSPDFKit will still run and work great under iOS 6.

Changed

Fully compatible and tested with iOS 7.1 and Xcode 5.1.
Changed

God dag! We've added Swedish to the list of presupplied localization files.
Changed

All-new flexible annotation toolbar (PSPDFFlexibleAnnotationToolbar) that can be dragged to be vertical or horizontal. See PSPDFAnnotationToolbarType in the PSPDFAnnotationBarButtonItem to optionally keep using the old annotation toolbar.
Changed

PSPDFKit Complete can now create digital signatures. This feature is still in beta - we need more documents to test all possible conditions. If you're having issues with this, please contact us so we can further increase the test coverage.
Changed

Text selection now supports text-to-speech on iOS 7+. See PSPDFSpeechSynthesizer for details and options to customize the language.
Changed

Forms on iPhone/iOS 7 now have an automatic zoom feature that makes it a lot easier to enter text.
Changed

Search now also includes annotation and form element contents. This is especially useful for note annotations and forms. (PSPDFKit Basic/Complete)
Changed

Search results are now hidden on page tap (unless that tap finds an action like selecting an annotation.)
Changed

Note annotations are now always rendered at the same size and also visible in the thumbnails.
Changed

PDF annotation writing will now be faster and produce a more compact trailer, reducing target file size.
Added

Adds support for mailto: links with multiple email addresses (also for CC and BCC).
Changed

Saving will now use the correct z-index for annotations and forms in the same ordering as they are added. Saving changed objects will no longer change the z-ordering.
Changed

Simple JavaScript actions like printing, alert boxes or adding form values now work. If you have a use case for that, please contact us at support@pspdfkit.com.
Changed

The XFDF parser now parses basic rich text strings as used in Acrobat and keeps color and font informations.
Changed

Increases contrast for the selection color on form choice list-boxes.
Changed

PSPDFTextSelectionView now allows UIAppearance to customize selectionColor and selectionAlpha.
Changed

The PSPDFActivityViewController now checks if printing is allowed for the document before even showing the print option.
Changed

No longer ends the text view edit mode when zooming on iOS 7 (flat mode) and above.
Changed

File annotations are now evaluated lazily, which improves startup performance for documents with many such annotations.
Changed

Note annotations now also create popup annotation on PDF saving. These are optional but increase compatibility with certain less standard-compliant 3rd-party software.
Changed

The behavior of the pdfViewController:didTapOnPage:View:atPoint: has been updated when no PSPDFPageView was hit to return nil here, and coordinates relative to the current PSPDFViewController.
Changed

The PSPDFThumbnailBar has a new parameter to optionally enable the page labels: showPageLabels (defaults to NO).
Changed

Many improvements related to PDF AcroForm handling and input validation.
Changed

Calls to didHidePageView: and didShowPageView: of views with the PSPDFAnnotationViewProtocol are now properly balanced.
Changed

The text parser now has a more sophisticated text shadow/overlay detection, which improves search results by removing duplicated glyphs.
Changed

The gallery has a new mode that enables live-blur behind the content (see blurEnabled on PSPDFGalleryViewController).
Fixed

Fixes an issue where the popover might open at an unexpected location when using the inline multimedia system with the popover:true parameter.
Changed

Font annotations are now rendered with their AP stream for greater document accuracy.
Changed

Annotations now support the additional action mouse up event.
Changed

Greatly improves speed for the XFDF image deserialization process.
API

PSPDFKit now requires the Accelerate.framework. If you're using the PSPDFKit.xcconfig file, you don't need to change anything.
API

Search related methods are now in the new searchHighlightViewManager property of PSPDFViewController.
API

The HUD and related views have been reorganized. You might have to update some calls (some views are now within HUDView)
API

PSPDFProgressHUD has been replaced with the all-new PSPDFStatusHUD, which features a modern iOS 7 design and an improved API.
API

PSPDFDocument should be treated as an immutable object (apart from settings). Thus, the files and fileURL properties have been made readonly, and appendFile: has been removed. Create a new document with the new files/data objects instead. Use the new helper documentByAppendingObjects: to create a modified document with a new file or data objects.
API

The PSPDFAnnotationManager now supports various protocol strings, thus the property protocolString has been renamed to protocolStrings and is now an NSArray that takes NSStrings. We've added embed:// as a second, neutral protocol format.
API

The textSearch class has been moved from PSPDFDocument to PSPDFViewController.
API

PSPDFNoteAnnotationViewFixedSize has been removed. Notes are now drawn with a fixed size, however you can define the bounding box to whatever you like. We recommend using 32px, but this value is being ignored by both PSPDFKit and Adobe Acrobat. Other, less capable renderers like Apple Preview.app might use the value, so 32px is a good value - but also depends how large or small your document is.
API

The PSPDFSignatureViewController no longer dismisses itself. Dismiss the controller in the delegate callbacks.
API

Code and subclassing hooks that could be used to change the PSPDFScrobbleBar frame have been moved to PSPDFHUDView.

Fixed

Fixes a stability issue related to autodetecting link types.
Fixed

Fixes an issue related to exporting appearance streams via XFDF.

3.5.0 - 10 Feb 2014

API

The PSPDFAnnotationToolbar has been modularized and all state related code is now in PSPDFAnnotationStateManager, which is a property of PSPDFViewController. You might have to update your subclasses to reflect these changes. PSPDFAnnotationStateManager should now be used instead of a headless PSPDFAnnotationToolbar if you have your own toolbar.

3.3.0 - 29 Dec 2013

Happy holidays!

PSPDFKit now requires iOS 6+ and Xcode 5. Keep using PSPDFKit 3.2.x if you're still building with Xcode 4.6 or need to support iOS 5. Apple will enforce usage of Xcode 5 starting February 1st. (https://developer.apple.com/news/index.php?id=12172013a) Removing iOS 5 resulted in deleting almost 10.000 lines of code - which will give you a smaller, faster and more efficient binary.

The binary is now again fully universal including armv7, armv7s, arm64, i386 and x86_64. The separate iOS 7 only (64 bit) library variant has been removed.

PSPDFKit Complete now supports PDF form signature validation and thus links with OpenSSL. There is an optional build without OpenSSL that disables these cryptographic signature checks.

Changed

Localization! PSPDFKit now ships with English, Chinese, Korean, Japanese, French, Spanish, Russian, Italian, Danish, German, Portuguese and Brazilian Portuguese.
Added

Adds preliminary compatibility with Xcode 5.1 and iOS 7.1b2.

Changed

PSPDFKit Complete/Enterprise can now validate cryptographic signatures (unless you use the build without OpenSSL)
Changed

PSPDFAESCryptoDataProvider now supports the popular RNCryptor data format: https://github.com/rnapier/RNCryptor/wiki/Data-Format (It autodetects the legacy format and supports that as well)

Improves automatic font resizing for single line text field form entries.
Changed

Improved support for additionalActions and nextAction to add actions to all annotation types.
Changed

API Change: PSPDFTextSelectionMenuActionWikipediaAsFallback has been renamed to PSPDFTextSelectionMenuActionWikipedia. Since checking for a word in UIReferenceLibraryViewController can be unpredictably slow as of iOS 7.0.3, we had to remove this feature. Define will now always be displayed and you can optionally enable Wikipedia as well. The new default will omit Wikipedia by default.
Changed

Don't show the PSPDFWebViewController bottom toolbar on iPhone if there are no availableActions defined.

3.2.2 - 24 Nov 2013

Changed

The gallery now allows image zooming when in full screen and requires less memory when loading remote images.

Changed

The PSPDFDocumentSharingViewController will now use a temporary directory to save annotations into the PDF if it's in a non-writable location.
Changed

The password view now automatically shows the keyboard.
Changed

If annotations can't be embedded, the new annotation menu will not be displayed anymore (to be consistent with the PSPDFAnnotationBarButtonItem)
Changed

The runtime now better deals with multiple annotation subclasses that both change the behavior of a parent class. Use overrideClass:withClass: on PSPDFDocument to register such subclasses.
Changed

Set the default ink line width to 3, unless a default is already set.
Changed

Using undo/redo while in eraser mode will now also allow adding/removing of ink annotations.
Changed

The undo system will now commit expired actions that are coalesced. This fixes an issue where certain actions would appear undo-able quite late (e.g. first erase action)

Changed

PDF Signature Form elements are now tappable and will offer to add a ink annotation as signature.
Changed

3.2.0 - 10 Nov 2013

Changed

Lots of improvements around sound annotations! Serialization, better selection, context menus, customization.
Changed

PSPDFAnnotationTableViewController: Dynamically calculate cell height and show multiple lines of description per cell.
Changed

Changed

PSPDFViewController will now auto-save annotations when the view is dismissed while contained in a child view controller.
Added

Add verticalTextAlignment to PSPDFFreeTextAnnotation. This is not defined in the PDF spec; so it will be a code-only option for now. PSPDFKit will save this into the PDF as a proprietary extension.

3.1.0 - 18 Oct 2013

Changed

Brand-new image gallery (define a region in the pdf to be covered by a smooth gallery). Allows configuration via inline-pdf or external JSON.
Changed

Use menu-based annotation manipulation for text markup annotations.
Changed

The way how the document UID is generated has been changed. Previously, for files it used the full app path. However since the app UID could change after an upgrade, we had to change this behavior. This is only important if you used bookmarks or allowed annotations saving into the internal storage - not for embedded annotation data. Set the global variable PSPDFUseLegacyUIDGenerationMethod to YES to continue using the old path. Those files are in Library/PrivateDocuments. You might want to write a custom migration step to rename the custom data paths from the old UID to the new UID system. The PSPDFUseLegacyUIDGenerationMethod can be changed at any time to switch between old and new UID (generate a new PSPDFDocument instance to force UID regeneration).
Changed

The file-based annotation backing store by default no longer saves link annotations but instead merges the saved annotations and the links from the file. This improves performance for PDFs that have lots of internal links (our current way of saving starts to get slow once there are more than 10.000 objects). In most cases, you don't need to care and your save file will be migrated automatically. If you rely on custom link annotations being saved/deleted, you need to set the new saveableTypes property of the fileAnnotationProvider back to the old default PSPDFAnnotationTypeAll.
Changed

The undo/redo buttons are now updated immediately after adding annotations.

Important! Currently PSPDFKit 3 requires that you set the key UIViewControllerBasedStatusBarAppearance to false in your project Info.plist file. We're working on supporting view controller based status bar appearance in a future update.

Note: Several methods and constants have been updated and renamed to make the API cleaner. Read the PSPDFKit 3.0 Migration Guide if you're updating from version 2.

Important: PSPDFKit 3 requires a serial number and will run in demo-mode by default. Visit https://customers.pspdfkit.com to register your app bundle ID and get the serial. If you are a PSPDFKit 2 customer with a license that includes a free PSPDFKit 3 update, please contact support@pspdfkit.com with your PET* purchase number to get an invite.

PSPDFKit 3 still supports iOS5, however we plan to drop support for it later this year. We already see less than 5% usage and expect this number to drop further in the future.

With the release of PSPDFKit 3 we will focus development on this version and won't be able to offer support for version 2 anymore. Most customers who bought PSPDFKit after January 14th are eligible for a free update, if your update window is still open (6 months for Binary/Viewer, 12 months for Source/Enterprise) Contact us with your PET* purchase number (or invoice ID) for details on your status.

You can disable this with nilling out the styleKeys property of PSPDFStyleManager.
Changed

The PSPDFFreeTextAnnotationView is now always sharp, even when zoomed in. Because we have to work around the broken contentsScale property, the API has changed a bit. If you previously had textView overridden, you now need to subclass PSPDFFreeTextAnnotationView and change the textViewForEditing method to apply your custom textView.
Changed

PSPDFStampViewController is now more flexible and will evaluate the new PSPDFStampAnnotationSuggestedSizeKey key for the default annotations.

Now you can create outline elements and bookmark that have the same flexibility as links in PSPDFLinkAnnotation, supporting pspdfkit:// style URLs. The parsing code has been unified as well with the best of both worlds (e.g. the 'Launch' action is now supported universally). This improvement required deprecating certain methods - update your code if you used one of those classes directly)
Added

Add support for GoBack/GoForward named annotations.
Added

Add basic support for JavaScript actions that link to another page.
Changed

PSPDFNoteAnnotationController now honors the allowEditing state also for the textView and blocks editing if set to NO.

PSPDFViewState no longer saves the HUD status (this should be handled separately and was confusing for the tabbed controller)
Removed

Removed legacy coder support for data models that were serialized before 2.7.0.
Removed

Removes deprecated API support in PSPDFTextSearch and PSPDFAnnotationParser.
Fixed

Fixes an issue in the label parser where page label prefixes were defined without style.
Fixed

Fixes an issue where hiding the progress HUD could make the wrong window keyWindow (if at that time there is more than one visible), thus leading to keyboard problems.
Fixed

Fixes an issue in the document parser that could lead to a recursion for cyclic XRef references for certain PDF documents.
Fixed

Fixes a situation where touch handling could become sluggish when a crazy amount of link annotation is on a page (>500!)
Fixed

Fixes a annotation text encoding issue that could result in breaking serialization of certain character combinations like 小森.
Fixed

Fixes a UI issue where invoking the draw action from the menu while at the same time having the annotation toolbar visible could lead to a hidden toolbar if that one is transparent.
Fixed

Fixes an issue with the text extraction engine for certain PDF files.
Changed

Appcelerator: Allow setting size properties like thumbnailSize: [300,300]
Changed

Appcelerator: Add support to set outline controller filter options (outlineControllerFilterOptions = ["Outline"])

2.11.2 - 4 Apr 2013

Changed

Drawing annotations is now always sharp, even when the document is zoomed in. (This required changes to the public API of PSPDFDrawView, check your code if you use that class directly)
Changed

Annotation flattening now shows a circular progress indicator instead of the default spinning indicator.
Changed

PSPDFProcessor now has a new progressBlock property that calls back on each processed page.

If a new PSPDFViewController is created based on a PDF action that links to a new document modally, all important settings are copied over to the new controller.
Changed

PSPDFKit will no longer create empty highlight annotations when using the annotation toolbar and tapping on a point without text.
Changed

No longer retains the view controller while the document background cache is being build (less memory pressure)
Added

Adds some more safeguards against abuse of certain methods.
Changed

The render queue now retains the document while rendering. This fixes cases where image requests never returned because the document disappeared before.
Fixed

Fixes a regression from 2.10 where through an event optimization sometimes the text of a note annotation was not properly saved. PSPDFDocument now sends out a PSPDFDocumentWillSaveNotification before a save will be made to give all open editors a chance to persist it's last state in time.
Fixed

Fixes an issue where the contentRect was calculated wrong for uncommon view embedding use cases.
Fixed

Fixes an issue where the thumbnail filter values were hardcoded.
Fixed

Changed

The render queue now better prioritizes between cache requests and user requests (zooms) to allow even faster rendering.
Changed

FreeText annotations can now no longer be created outside boundaries.
Added

Add support for text alignment for FreeText annotations. (It seems that Adobe Acrobat has a bug here and ignores this property - other Applications are compliant to the PDF spec and do display this, e.g. Apple's Preview.app)
Changed

Edit mode now directly hides the HUDView.
Changed

API change: The color picker now has a context: flag to allow state storage. Update your delegates if you use this class directly.
Fixed

Fixes some minor issues with the new cache.
Fixed

Fixes a UI weirdness where the scrollview had a slow scroll-back animation when text was edited at the very top.
Changed

Titanium: Add new linkAnnotationHighlightColor property.

2.10.0 - 22 Mar 2013

PSPDFKit 2.10 is another major milestone. The cache has been rewritten from the ground up to be both faster and more reliable. Annotations are now cached, they are no longer an "afterthought" and will show up in the thumbnails and even the scrobble bar. The disk cache now limits itself to 500MB (this is customizable) and cleans up the least recently used files. The memory cache is now also smarter and better limits itself to a fixed number of pixels (~50MB of modern devices in the default setting). Loading images from the cache is now more logical and highly customizable with PSPDFCacheOptions. The two render code paths have been unified, PSPDFRenderQueue now does all rendering and can now render multiple requests at the same time and also prioritizes between low priority cache requests and high priority user zoom requests. In this process some very old code has been completely reworked (PSPDFGlobalLock) and is now much more solid. Several methods have been renamed, upgrading will require a little bit of effort to adapt to the new method names. It's definitely worth it. If you find any regressions or missing features for your particular use case, contact me at peter@pspdfkit.com.

Changed

Completely rewritten cache that now renders all screen sizes and shows annotations.
Changed

PSPDFThumbnailViewController now has a new filter to only show annotated/bookmarked pages. See filterOptions for details. http://twitter.com/PSPDFKit/status/314333301664006144/photo/1

Prevent too fast tableView updates (and thus flickering) in PSPDFSearchViewController.
Changed

Increases loupe magnification on iPhone to 1.6 and make kPSPDFLoupeDefaultMagnification customizable at runtime.
Changed

A UISplitViewController in the hierarchy is automatically detected and the pan gesture will be blocked while the PSPDFViewController is in drawing mode (else this would interfere with drawing).
Changed

The note annotation controller now no longer generates change events per typed key, but will wait for a viewWillDisappear/app background event to sync the changed text back into the annotation object.
Changed

Expose availableLineWidths and availableFontSizes in PSPDFPageView to customize menu options.
Changed

On iPhone, scrolling down the search results will now automatically hide the keyboard.

Add workaround against rdar://13446855 (UIMenuController doesn't properly reset state for multi-page menu)
Changed

The selectionBackgroundColor of PSPDFSearchHighlightView can be updated after it's displayed now.
Changed

PSPDFTabBarView of PSPDFTabbedViewController can now be overridden with the overrideClassNames dictionary.
Changed

API change: The renderBackgroundColor, renderInvertEnabled, renderContentOpacity methods have been removed from PSPDFViewController. Please instead update the dictionary in PSPDFDocument to set these effects. (e.g. document.renderOptions = @{kPSPDFInvertRendering : @YES}).
Changed

API change: PSPDFViewController's renderAnnotationTypes has been deprecated and will update the renderOptions in PSPDFDocument instead.
Changed

API change: renderPage: and renderImageForPage: will now automatically fetch annotations if the annotations array is nil. To render a page without annotations, supply an empty array as the annotations array (as soon as an array is set, auto-fetching will be disabled).

Changed

UIMenuController is now smarter and no longer places the menu above the toolbar when there's space underneath as well.
Changed

'allowTwoFingerScrollPanDuringLock' in PSPDFAnnotationToolbar now defaults to NO, since this delays drawing.
Changed

API change: Refactored the thumbnail view out of PSPDFViewController into it's own controller: PSPDFThumbnailViewController. If your code relied on modifying the collection view delegates within PSPDFViewController, you must update your code to override PSPDFThumbnailViewController instead. PSPDFViewController' gridView has been deprecated. Use thumbnailController.collectionView instead.
Changed

API change: Removed iPhoneThumbnailSizeReductionFactor. item size is now set conditionally during initialization. The best way to set this is in PSPDFCache.sharedCache.thumbnailSize.
Changed

2.8.6 - 20 Feb 2013

Changed

PSPDFShapeAnnotation now creates appearance stream data. This is needed to work around a bug in Adobe Acrobat for iOS. This behavior can be disabled with setting kPSPDFGenerateAPForShape to @NO in renderingOptions of PSPDFDocument. As a side effect, this also improves display of transparent shapes with Apple's Preview.app
Changed

Improvements to smart zoom - text block choose method is now smarter.
Changed

viewLock no longer locks the HUD (just the view state)
Changed

Improves animation for the Table of Contents controller cells.
Changed

Changed

Various typos fixed, and some very minor API changes due to spelling corrections (thanks to Tony Tomc).

2.8.1 - 6 Feb 2013

Changed

The highlight tool now matches full words. A single touch will highlight the complete word instead of just one character.
Changed

A new syntax for link annotations to control UI. For now pspdfkit://control:outline is supported to open the TOC directly from the document.
Changed

The signature controller now uses "Signatures" as title instead of "Choose Signature" on iPhone, since later was too long and got cut off.
Fixed

Fixes an issue where setFileURL: could generate a new UID if one was already set.
Fixed

Fixes an UI issue when resizing an annotation purely horizontally would result in no redraw.
Fixed

Fixes an UI issue where the thumbnail indicator could move behind the thumbnail image in some cases.

Changed

Image annotations. PSPDFKit can now add images from the camera and the photo library and embed them as stamp annotations.
Changed

Search / Text extraction is now more than twice as fast and reports the current page.
Changed

The whole AP stream generation system has been improved and performance optimized to allow bigger streams like images.
Changed

PSPDFKit will now require Xcode 4.6/SDK 6.1 to compile. (4.5 should still work fine, but we follow Apple's best practice with always compiling with the latest SDK available.)
Changed

API change: editableAnnotationTypes is now an ordered set. Using a regular set to change this property will work for the time being, but please update your code. The order now will change the ordering of the buttons in the annotation toolbar and the new annotation menu.
Added

Add experimental phone/link detection: detectLinkTypes:forPagesInRange: in PSPDFDocument. This will create annotations for phone numbers and links found in the document, if they are not linked already. This is the same that Preview/Mac and Adobe Acrobat do - they allow to click URLs even if they don't have any link set on them.
Changed

Search now displays the current processed page.
Changed

Further tweaks to PSPDFHighlightAnnotation highlightedString.
Added

Add setting to enable/disable the "Customer Signature" feature. (customerSignatureFeatureEnabled in PSPDFSignatureStore)
Changed

The signature controller has now landscape as preferred rotation under iOS6. (but still supports portrait)
Changed

Controllers presented via the PSPDFViewController helper now use a custom PSPDFNavigationController that queries the iOS6 rotation methods of the topmost view controller. This makes it easier to customize rotation for PSPDF* controllers without hacks.
Changed

Performance improvement: deleted annotations now are no longer serialized if the external annotation format is used.
Changed

The "hide small links" feature now works better on iPhone.
Changed

FreeText annotations now parse even more font definition styles.

The font selector now selects the currently chosen font.
Changed

Various performance improvements. (esp. search and the color picker)
Changed

Thumbnails are now sharper and always aligned to pixel grid (fixes a bug in UICollectionViewFlowLayout)
Changed

Fixed

Fixes an UX issue where a tap wasn't set to being processed when the delegate delegateDidTapOnAnnotation:annotationPoint:... was being used.
Fixed

Fixes an UIKit bug that in some cases froze the UIScrollView when we zoomed out programmatically (e.g. a double tap after already zoomed in)
Fixed

Fixes an issue with searching for certain characters that are reserved regex characters (like *+).
Fixed

Fixes an encoding issue with annotation content and certain Chinese characters.

2.7.5 - 25 Jan 2013

Changed

Signatures are now securely saved in the Keychain and a list of signatures is presented. To disable this feature, set PSPDFSignatureStore.sharedSignatureStore.signatureSavingEnabled = NO in your appDelegate.
Changed

While annotation mode is active (highlight, drawing, etc) scrolling is now enabled with using two fingers. The old behavior can be restored with setting allowTwoFingerScrollPanDuringLock in PSPDFAnnotationToolbar to NO.

PSPDFKit now requires Security.framework.
Fixed

Fixes an issue that could cause an initial "white page" when the controller is first loaded, even when there's cache data available.

Added

Add more audio file formats to the support list. (aiff, cif, ...)
Changed

Ensure that addAnnotation:animated: in PSPDFPageView sets the page and documentProvider.

2.7.0 - 16 Jan 2013

Changed

PSPDFKit model classes now have a common base model class 'PSPDFModel' - allows to serialize/deserialize via JSON easily using externalRepresentationInFormat:. To get the JSON dictionary, use annotation externalRepresentationInFormat:PSPDFModelJSONFormat. (The old annotation serialization format is still supported for the time being)
Changed

PSPDFKit now requires AssetsLibrary.framework - if you're using PSPDFKit.xcproj or the source distribution, this is already been taken cared of. If you added the frameworks manually and get a linker error, make sure you are linking sAssetsLibrary.framework.
Changed

PSPDFMenuItem learned to show images in UIMenuController - this beautifies many of the annotation menus, images are now used for annotation types/colors where appropriate.
Changed

PSPDFKit has learned to write appearance streams. Currently they are emitted for Stamp and Ink annotations. This will help to further improve annotation compatibility with some apps that behave less standard compliant (like Adobe Acrobat/iOS, last tested version is 10.4.4, which doesn't show Ink annotations if they do not have an attached AP stream, even if this is invalid behavior according to the PDF spec. (GoodReader/Preview.app/Adobe Reader on the Mac don't require an AP stream and work in compliance to the spec.))
Changed

Annotation menus have been cleaned up a little, Opacity... has been moved into a submenu of Color for highlight annotations.
Changed

PSPDFProcessor has learned to write annotations as dictionary, not only flatten. This will be used e.g. for Open In... when the original PDF is not writeable and thus annotations are saved in an external file.
Changed

Open In... will now create a new file if there are annotations and the source PDF is not writeable itself.
Changed

Stamp annotations now have limited support for appearance streams.
Changed

Stamp annotations can now be added via the new PSPDFStampViewController.
Added

Add experimental pageRange feature in PSPDFDocument to allow showing of a subset of the pages.
Changed

Highlight annotation hit testing is now more accurate, checking the specific rects of the highlights, not the outer boundingBox.
Changed

Annotation rendering now checks if the annotation will be visible at all and only then renders the annotation. This speeds up zooming on complex documents with many annotations.
Changed

Improves search by ignoring certain whitespace characters like no-break-spaces.
Changed

Allows to create password protected PDFs with PSPDFProcessor up to AES-128 (and mix other CGPDFContext properties like kCGPDFContextAllowsPrinting or kCGPDFContextAllowsCopying)
Changed

Improves word detection with splitting words between a line of thought and adding special logic for non-default whitespace characters. to use the old behavior.
Changed

Improves french translation.
Changed

zIndex of annotation images is now below zIndex of links, so that links are always displayed before annotation images.
Changed

Email sending using PSPDFEmailSendMergedFilesIfNeeded will not perform a merge if there is only one source document.
Changed

Links are now handled even if they are overlapped or hidden underneath other views.
Changed

Hides the page label and the scrobble bar if the document is password protected and not yet unlocked.
Changed

PSPDFAnnotation now shows if an appearanceStream is attached.
Changed

PSPDFAnnotation now as a userInfo dictionary to add any custom data.
Changed

Annotations now have a creationDate.
Changed

When note annotations are tapped, don't fade-animate the former annotation out.
Changed

Page label will not be displayed if the page label is simply the real page number. (Prevent titles like 2 (2 of 10))
Changed

Changed

Selected images now have a (default iOS light blue) selection state, matching the selection behavior of glyphs.
Changed

Brightness control now has indicator images for less/more brightness and a better icon.
Changed

Improves performance for pages with many links by dynamically disabling the rounded corners in that case.
Changed

External PDF links can now be opened modally in a new controller, use [modal:YES] in the option field, e.g. pspdfkit://[modal:YES]localhost/two.pdf#page=4.
Changed

Video extension with a cover now no longer has a dark background and is transparent. If you set cover:YES it will simply show the play button without any background.
Changed

API change: Words are now detected if they are completely within the rect specified. Use kPSPDFObjectsTestIntersection
Changed

API change: OutlineElement.page is now 0-based, not 1-based.
Changed

API change: Several PSPDFProcessor methods now have an additional error part.
Changed

API change: PSPDFInkAnnotation has been simplified, will automatically recalculate bounding box and paths on line change.
Changed

API change: Setting the annotation color will now also set the alpha value, if one is set in color.
Changed

API change: objectsAtPoint: now automatically does an intersection test unless specified otherwise, but objectsAtRect will not, so you need to specify that. Also, in previous version the rect check was done incorrectly to check if the test rect is within the object, now we check if the object is within the test rect OR intersects with it, if intersection is set to YES.
Changed

API change: Links to external files now reference the page, not page+1. (pspdfkit://localhost/two.pdf#page=4 will move to page 4, before it was page 5)
Added

Add support for older PDF standard of defining Dest arrays for page links (for example those produced by LaTeX with PDF version 1.3)
Changed

Annotation option parsing is now more robust and will tolerate whitespace.
Changed

Annotation text (and thus the annotation menu) is now even displayed if editableAnnotationType is set to NO.
Added

Adds a workaround for certain PDFs with large embedded videos that previously couldn't be parsed.
Changed

PSPDFKit now uses OS_OBJECT_USE_OBJC instead of OS version checking to check of GCD objects are collected via ARC or not (This is iOS6 only and the new default, can be disabled by the compiler)
Changed

Text in the password view is now viewable on iPhone in landscape.
Fixed

KNOWN ISSUE: Annotations can't yet be moved between pages. This feature is on our roadmap.

2.4.0 - 2 Nov 2012

PSPDFKit now requires iOS 5.0+ and Xcode 4.5+ (iOS SDK 6.0) to compile. (Support for iOS 4.3/Xcode 4.4 has been removed, support for iOS 6.1 and Xcode 4.6b1 has been added.)

2.4 is a big release and a great new milestone of PSPDFKit. If you upgrade, make sure to read through the full header diffs to make sure methods you were calling/overriding still exist and are not moved. Common methods like pageScrolling will always get a compatibility method for the time being. Methods/Properties are are deeper within the framework won't get a compatibility method, but it's usually pretty easy to figure out what the property was named before. I am planning on working on PSPDFKit for a long time, and as the API evolves, it's sometimes necessary to clean up and rename things so that the API stays clean and logical.

Changed

Huge refactoring of PSPDFAnnotationParser. It's now much easier to add custom annotation providers (see PSPDFAnnotationProvider). If you have subclassed saving/loading or other parts of PSPDFAnnotationParser, you most likely need to change this over to the new PSPDFFileAnnotationProvider.
Changed

Page scrolling is now even smoother. And finally removes the slight stuttering when pushing the PSPDFViewController - now animates like butter.
Changed

PSPDFShapeAnnotation can now be saved into the PDF.
Changed

Ink drawings can now customize the Thickness. Select an annotation and use the new "Thickness..." menu item.
Changed

Ink drawings and shape annotations can now also contain comment text.
Changed

Annotations now support the title/user "T" flag. Change the default user name by changing the property in PSPDFFileAnnotationProvider.
Added

Add support for embedded and external RichMedia and Screen (Video) annotations of any size.
Changed

PSPDFBarButtonItem now has longPress-support. Long-Press on the bookmarkBarButtonItem to see the new PSPDFBookmarkViewController. Bookmarks can now also be renamed/reordered.
Changed

If there's no searchButton visible, the search invoked from the text selection menu now will originate from the selection rect.
Changed

The Open In... action now also works on multi-file documents and/or data/cgdocumentprovider based documents (will merge the document on-the-fly, shows a progress window if it'll take some time)
Changed

PSPDFBarButtonItem now also accepts a generic UIView as sender on presentAnimated:sender:. (makes it easier to manually call menu items from custom code)
Changed

Better support when barButtonItems are added to custom UIToolbars.
Changed

The internal used BarButtonItem subclasses are now exposed, so that they can be overridden and their icon changed.
Added

New activityBarButtonItem to share pages to Facebook/Twitter on iOS6.
Changed

Double-Tapping on a video now enables full-screen (instead of zooming the page. This does not apply to YouTube movies)
Changed

Greatly improves handling of multiple video views on one page/screen.
Changed

Annotation views now have a optional xIndex. Video has a high index by default, so link annotations won't overlap a video anymore.
Changed

No longer allowing text selection above video annotations.
Changed

PSPDFDocument now has a new property 'PDFBox' to customize the used PDF box (ClipRect/MediaRect/etc).
Changed

PSPDFPositionView has been renamed to PSPDFPageLabelView. PSPDFPageLabelView and PSPDFDocumentLabelView are now easier skinable with the common superclass PSPDFLabelView.

Changed

Setting the UIPopoverController no longer removes preexisting passthroughViews.
Changed

The renderQueue now no longer renders the requested image if the delegate has been released in the mean time. (The delegate is now weak instead of strong)

PSPDFPageInfo is not calculated in PSPDFDocumentProvider. If you've overridden methods that affect PSPDFPageInfo in PSPDFDocument, you should move that code to a PSPDFDocumentProvider subclass.
API

"realPage" has been renamed to "page" and is now set-able. The old "page" has been renamed to "screenPage". This finally cleans up the confusion that has been around page and realPage. In 99% of all cases, you're just interested in page and can ignore screenPage. Please update your bindings accordingly. If you formerly did KVO on realPage, change this to page too. (There's a deprecated compatibility property for realPage, but not for the KVO event)
API

API

Warning! If you've used pspdf_dispatch_sync_reentrant in your own code, you now absolutely must create your dispatch queues with pspdf_dispatch_queue_create. Apple has deprecated dispatch_get_current_queue(), so we're now using a different solution. This will most likely affect you if you're using the "Kiosk" sample code of PSPDFCatalog.

2.1.0 - 17 Sep 2012

Changed

New: PSPDFAESCryptoDataProvider. Allows fast, secure on-the-fly decryption of AES256-secured PDF documents. (PSPDFKit Annotate feature) Unlike NSData-based solutions, the PDF never is fully decrypted, and this even works with very large (> 100MB) documents. Uses 50.000 PBKDF iterations and a custom IV vector for maximum security. Includes the AESCryptor helper Mac app to properly encrypt your PDF documents.
Changed

Allow to customize caching strategy per document with the new cacheStrategy property. This is automatically set to PSPDFCacheNothing when using PSPDFAESCryptoDataProvider.

Adds new isWriteable static method to PSPDFAnnotation subclasses to determine what classes can be written back to PDF.
Added

Add kPSPDFAllowAntiAliasing as optional render option.
Changed

PSPDFOpenInBarButtonItem no longer performs a check for compatible apps. Checking this is pretty slow. An info alert will be displayed to the user if no compatible apps are installed (which is highly unlikely for PDF). You can restore the original behavior with setting kPSPDFCheckIfCompatibleAppsAreInstalled to YES.
Changed

The viewState is now preserved when another controller is displayed/dismissed modally. This mostly happened with showing/hiding the inline browser or the note text controller on an iPhone. After that the zoom rate was reset; this is now properly preserved.
Changed

The annotation toolbar now flashes if the user tries to hide the HUD while the bar is still active (and blocking that)
Changed

Various performance optimizations; especially scrolling and initial controller creation.
Removed

Removes sporadic vertical transition of the navigationController's navigationBar when HUD faded out.
Fixed

Fixes "Persistent Text Loupe" when moving over a link annotation while selecting.

Faster search (document pattern detection if delayed until needed, outline results get cached)
Changed

Improved reaction time for complex PDF documents (e.g. annotations are only evaluated if they're already loaded; but won't lock the main thread due to lazy parsing)

Add additional checks so that even incorrectly converted NSURL-paths (where description instead of path has been called) work.
Fixed

Fixes a issue where annotations were not saved with multiple-file documents on all but the first file.
Fixed

Changed

Improved memory usage, especially on iPad1.

2.0.0 - 8 Sep 2012

PSPDFKit 2 is a major updates with lots of changes and a streamlined API. There are some API deprecations and some breaking changes; but those are fairly straightforward and well documented.

You need at least Xcode 4.4.1 to compile. (Xcode 4.4/4.5 both run fine on Lion, Mountain Lion is not needed but recommended) PSPDFKit 2 is compatible with iOS 4.3 upwards. (armv7, i386 - thus dropping iOS 4.2/armv6 from version 1)

The installation has been simplified. You now just drop the "PSPDFKit.embeddedframework" container into your project. Next, enable the PSPDFKit.xcconfig project configuration. Here's a screenshot: http://cl.ly/image/1e1I2Z2e1D3F (Select your project (top left), select project again in the PROJECT/TARGETS tree, select Info, then change in "Based on Configuration file" from None to PSPDFKit.)

If you have the sources and embed PSPDFKit as a subproject, don't forget to also add PSPDFKit.bundle.

MAJOR NEW FEATURES: * Text selection! (PSPDFKit Annotate) (Includes Copy, Dictionary, Wikipedia support) * Annotations! (PSPDFKit Annotate) Highlight, Underscore, Strikeout, Note, Draw etc. Annotations also will be written back into the PDF. There is a new annotationBarButtonItem that shows the new annotation toolbar. * Smart Zoom (Text blocks are detected and zoomed onto on a double-tap; much like Safari) The PDF is now also dynamically re-rendered at every zoom level for maximal sharpness and quality. * Customizable render modes (enable/disable use of upscaled thumbnails). PSPDFPageRenderingModeFullPageBlocking is great for magazines. * Greatly improved Search. Faster, parses more font styles, compatible with international characters (chinese, turkish, arabic, ...) * Site Bookmarks (see bookmarksBarButtonItem and PSPDFBookmarkParser) * Support for VoiceOver accessibility (yes, even within the PDF!)

Further, PSPDFKit has been improved in virtually every area and a lot of details have been tweaked.

Changed

Inline password view. (Before, just a empty screen was shown when document wasn't unlocked.)
Changed

Adobe DRM detection (They are just marked as not viewable, instead of showing garbage)
Changed

PDF rendering indicator. (see pdfController.renderAnimationEnabled)
Changed

Even better view reuse. PSPDFPageView is now reused, scrolling is even smoother.

Changed

PSPDFPageView no longer uses CATiledLayer; this has been replaced by a much faster and better custom solution.
Changed

1.10.0 - 25 May 2012

This will probably be the last major release in the 1.x branch. Work on 2.x is already underway, with a focus on text selection and annotations.

This release has some API-breaking changes:

Added

New toolbar handling (breaking API change) The properties searchEnabled, outlineEnabled, printEnabled, openInEnabled, viewModeControlVisible have been replaced by a much more flexible system based on the PSPDFBarButtonItem class.

For example, to add those features under the "action" icon as a menu, use this: self.additionalRightBarButtonItems = [NSArray arrayWithObjects:self.printButtonItem, self.openInButtonItem, self.emailButtonItem, nil]; If you're looking to e.g. remove the search feature, set a new rightBarButtonItems array that excludes the searchButtonItem.

Likewise, the functions additionalLeftToolbarButtons, magazineButton and toolbarBackButton have been unified to self.leftBarButtonItems. If you want to replace the default closeButton with your own, just create your own UIBarButtonItem and set it to self.leftBarButtonItems = [NSArray arrayWithObject:customCloseBarButtonItem];

Changed

Resolving pdf link paths has changed. (breaking API change) Previously, if no marker like "Documents" or "Bundle" was found, we resolved to the bundle. This version changes resolving the link to the actual position of the pdf file. If you need the old behavior, you can set PSPDFResolvePathNamesEnableLegacyBehavior to YES or use a custom subclass of the PSPDFAnnotationParser.
Changed

New class PSPDFTabbedViewController, to show multiple PSPDFDocuments with a top tab bar. iOS5 only. (includes new TabbedExample)
Changed

New feature: PDF page labels are parsed. (e.g. roman letters or custom names; displayed in the PSPDFPositionView and the thumbnail label)
Changed

New feature: send via Email: allows sending the pdf as an attachment. (see emailButtonItem in PSPDFViewController)
Changed

New feature: PSPDFViewState allows persisting/restoring of a certain document position (including page, position, zoom level). See documentViewState and restoreDocumentViewState:animated: in PSPDFViewController.
Changed

Add support for puny code characters in pdf URLs (like http://➡.ws/鞰齒). This uses the IDNSDK.
Changed

New property: useParentNavigationBar, if you embed the PSPDFViewController using iOS5 containment and still want to populate the navigationBar.
Changed

New property: pageCurlDirectionLeftToRight to allow a backwards pagination. (for LTR oriented documents)
Changed

New delegate: delegateDidEndZooming:atScale to detect user/animated zooming.
Changed

UI Improvement: Show URL in embedded browser title bar, until page is loaded with the real title.
Changed

General: Add french localization in PSPDFKit.bundle.
Changed

Core: PSPDFDocument now implements NSCopying and NSCoding protocols.
Changed

Fixes a problem where links with hash bangs (like https://twitter.com/#!/) where incorrectly escaped.

Changed

Fixes a problem where under rare conditions a spinlock wasn't released in PSPDFGlobalLock.
Changed

Changed

Link elements now don't interfere with double/triple taps and only fire if those gestures failed.

Added

Adds a sanity check for loading images, fixes a rare issue with images not showing up.

Changed

Titanium: Add ability to hide the close button.

Note: For pageCurl, Apple's UIPageViewController is used. This class is pretty new and still buggy. I had to apply some private API fixes to make it work. Those calls are obfuscated and AppStore-safe.

If you have any reasons to absolutely don't use those workarounds, you can add PSPDFKIT_DONT_USE_OBFUSCATED_PRIVATE_API in the preprocessor defines. (only in the source code variant) This will also disable the pageCurl feature as the controller will crash pretty fast when my patches are not applied.

Don't worry about this, I have several apps in the store that use such workarounds where needed, it never was a problem. Also, I reported those bugs to Apple and will keep track of the fixes, and remove my workarounds for newer iOS versions if they fix the problem.

Fixed

Fixes a regression with the Web-AlertView-action not working.

1.8.0 - 21 Dec 2011

Changed

Search Highlighting! This feature is still in BETA, but already works with many documents. If it doesn't work for you, you can disable it with changing the searchMode-property in PSPDFDocumentSearcher. We're working hard to improve this, it just will take some more time until it works on every document. As a bonus, search is now fully async and no longer blocks the main thread.
Changed

ARC! PSPDFKit now internally uses ARC, which gives a nice performance boost and makes the codebase a lot cleaner. PSPDFKit is still fully compatible with iOS4 upwards. You need to manually include libarclite.so if you are not using ARC and need compatibility with iOS4. Check the MinimalExample.xcodeproj to see how it's done. (You can drag the two libarclite-libraries directly in your project). If you use the PSPDFKit-lib.xcodeproj as a submodule, you don't have to think about this, Xcode is clever enough to not expose this bug here. See more about this at https://pspdfkit.com/guides/.
Changed

New default shadow for pages. More square, iBooks-like. The previous shadow is available when changing shadowStyle in PSPDFScrollView. The shadow override function has been renamed to pathShadowForView.
Changed

New: PSPDFDocument now uses the title set in the pdf as default. Use setTitle to set your own title. Title is now also thread-safe.
Changed

New Thumbnail-Framework (removed AQGridView). Faster, better animations, allows more options. Thumbnails are now centered. You can override this behavior with subclassing gridView in PSPDFViewController.
Changed

New: HUD-elements are now within hudView, hudView is now a PSPDFHUDView, lazily created.
Changed

New: Page position is now displayed like in iBooks at the bottom page (title is now just title)
Changed

Changed: Videos don't auto play per default. Change the url to pspdfkit[autoplay:true]://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8 to restore the old behavior (or use delegates).
Changed

Changed: viewMode does not longer animate per default. Use the new setViewMode:animated: to change it with animation.
