Removed
Deprecates PSPDFUserInterfaceView.thumbnailBarInsets, which did not do anything. (#19771)
Removed
Removes the optionsView property from PSPDFNoteAnnotationViewController(SubclassingHooks) because returning any other value would lead to a crash. (#19841)
Removed
Removes the declarations of -configureZoomView:forSpreadIndex:, and -configureScrollView: from PSPDFDocumentViewLayout(Subclassing). These methods were unimplemented, and not used internally. Calling them would have lead to an “unrecognized selector” crash. (#19841)
Removed
Removes the unimplemented PSPDFPageLabelView(SubclassingHooks) category. (#19841)
Removed
Removes the unimplemented subclassing hooks -cancelDrawingAnimated: and -doneDrawingAnimated: from PSPDFAnnotationStateManager. (#19841)
Removed
Removes the unimplemented category PSPDFSavedAnnotationsViewController(SubclassingHooks). Calling the method it declared would have lead to an “unrecognized selector” crash. (#19841)

Added
Adds biometric properties on PSPDFDrawView: pointSequences, pressureList, timePoints, touchRadii and inputMethod. Calling clear on PSPDFDrawView now also clears any currently collected biometric data. (#19800)
Changed
Marks the inherited initializer -[PSPDFMenuItem initWithTitle:action:] as unavailable because it cannot be used with this class. (#19841)
Changed

API
Deprecates shouldBeginEditModeWhenPresented on PSPDFNoteAnnotationViewController, and showNoteControllerForAnnotation:showKeyboard:animated: in favor of showNoteControllerForAnnotation:animated: on PSPDFPageView, as choosing to show the keyboard is now decided based on heuristics, if the user might want to start editing. (#14205)
Added
Adds UI to PSPDFNoteAnnotationViewController that enables the user to see existing reviews for a comment, add their own review status, or change their review status. (#14421)
Added

API
Adds isGenerated to PSPDFGlyph to check if the glyph is an autogenerated filler. (#14606)
API
PSPDFGlyph.indexOnPage is not -1 to indicate that it is a generated filler. Use PSPDFGlyph.isGenerated instead. indexOnPage can now be used to uniquely identify a glyph on a page, and is the index of the glyph in the PSPDFTextParser.glyphs array. (#14606)

Changed
The relationship between PSPDFXFDFAnnotationProvider and PSPDFFileAnnotationProvider is now more explicit. If you use XFDF for form filling, you now need to keep around both providers. Furthermore, the annotation manager now only saves into the first annotation provider implementing the save method. Previously all were called, which could have led to incorrect results. (#14323)
Fixed
Fixes a crash that could happen during application termination. (#14483)
Fixed
Fixes a lock inversion when setting up the document providers. (#14525)
Fixed
Fixes a potential crash when saving a document. (#14082)

Important: Calling removeAnnotations:options: on a PSPDFFileAnnotationProvider no longer posts PSPDFAnnotationChangedNotification! Deleted annotations are still being returned from dirtyAnnotations until the next save — like before. They are, however, not returned from annotationsForPageAtIndex: anymore. This behavior is also far less surprising. (#14305)
Fixed
Fixes a document corruption bug when the document has a header and is incrementally saved. (#14249)
Fixed
Fixes Catalog "XFDF Annotation Provider, Encrypted" example. (#13912)
Fixed

Fixed
Fixes potential deadlocks when opening a lot of documents. (#14503)
Fixed
Fixes an issue where PSPDFFile.fileData did not lazily memory map the file data when being called from user code. (#14539)

5.0.0 - 23 Oct 2015

See the announcement post.

PSPDFKit 5 is a major new version, introducing our own renderer and focusing on improving performance. It requires Xcode 7.1 and is compatible with iOS 8.0 - 9.1. This release is a huge usability improvement with Swift but also Objective-C, as we annotated all headers with generics. This release now shares our new core with our Android SDK to further improve quality and performance.

Changed
PSPDFKit now uses its own PDF renderer and no longer uses Apple's Core Graphics renderer, which means better performance, stability and quality. (#3737)
Changed
Undo and redo now remember individual lines drawn instead of the previous behavior where undo removed the whole annotation, once committed. (#2825)
Changed
The tabbed bar has been completely redesigned and now supports animations and reordering, not to mention it being much prettier. (#665)
Changed
View controllers are now presented using UIPresentationController and are much easier to handle and dismiss. (#3519)
- Changed
  We removed the popoverController and halfModalController properties, as these are now custom presentation styles.
Changed
Popovers are no longer dismissed on rotation. (#3519)
Changed
iOS 8 adaptivity is fully supported: view controllers swap between being popovers, half modal or full screen depending on context. (#3743)
- Changed
  A new presentation option has been added to prevent view controllers from adapting their presentation style: PSPDFPresentationNonAdaptiveKey.
Changed
The default presentation style has changed for presentViewController:options:animated:sender:completion: from PSPDFViewController and PSPDFPresentationActions. The default is now to use the presented view controller’s modalPresentationStyle, similar to the old PSPDFPresentationStyleForceModal style, which has been removed.
- Changed
  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
PSPDFScrobbleBar has been renamed to PSPDFScrubberBar to better express its purpose.
Changed
Querying for the annotation author name has been moved to before the annotation toolbar is displayed. (#3544)
Changed
Annotation creation can now be prevented on select PDF pages by adding a boolean key to the page dictionary (see allowAnnotationCreation on PSPDFPageInfo). (#4308)
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.

4.4.7 - 24 Jun 2015

WWDC week! We're hard at work to make sure PSPDFKit is a good citizen on iOS 9 and also grilled the UIKit engineers in San Francisco. This release features various first updates for the iOS 9.0b1 and Xcode 7. As usual, our strategy is to keep a stable PSPDFKit 4.4.x that works with SDK 8 (Xcode 6.3.2), supporting iOS 7, 8 and 9 (with some exceptions, like multitasking) - while at the same time we are also working on PSPDFKit 5, made for Xcode 7 and iOS 8+9. Expect PSPDFKit 5 some time in September before the iOS 9 GM.

3.6.0 - 16 Mar 2014

See the announcement post.

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 multiple issues related to forms on rotated pages.
Fixed
Fixes an issue related to annotation fetching and the pageRange feature of PSPDFDocument.
Fixed
Fixes multiple issues related to the ink eraser.

3.3.0 - 29 Dec 2013

See the announcement post.

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
Refreshed visuals for both iOS 6 and iOS 7. The icons are now much more polished and can be better customized. The remaining icons that were drawn in code are now all inside the PSPDFKit.bundle.
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)

Changed
The PSPDFAnnotationToolbar now displays the style picker for text markup annotations (highlights).
Changed
The PSPDFGalleryViewController now supports local/remote video and audio files next to images.
Changed
The internal PSPDFWebViewController now shows a progress bar, much like Safari on iOS 7.
Changed
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.
Changed
Allow detection for a PSPDFKit signature and blocks the "Copy" feature if detected. Will also be saved into the PDF as proprietary extension.

Changed
YouTube: Add support for http://youtu.be short-form URLs for embedding.
Changed
The note icon name is now properly serialized when using the XFDF annotation provider.
Changed
The XFDF provider now only saves if an annotation is changed. Deserialized annotations are set to be not dirty by default now.
Changed
Annotation and outline classes have been optimized to require less memory and reuse more objects internally.
Changed
Lots of code cleaning, improved documentation and some reorganization. The binary is now smaller and compiles faster.
Changed
Moves document parsing to a background thread, improves initial startup time for complex, large documents.
Changed
GoToR actions with target named destinations are now supported.
Changed
FreeText annotations are now correctly rendered and displayed even when their bounding box is too small for the text.
Changed
Audio recordings can now be time limited and the default encoding/bitrate can be customized in PSPDFAudioHelper.
Changed
The default set of stamps is now localizable and localized by default.
Changed
The Edit button in the annotation table view controller and the bookmark controller is now only enabled if there is content, and edit mode is automatically disabled when there's no more content.

Fixed
Fixes a rare crash in (poly)line point calculation if the points are on top of each other.
Fixed
Fixes an edge case where the text field would loose focus after the note annotation controller has been dismissed because of tapping into another text field.
Fixed
Fixes a regression where the selected annotation for multiple potentials was reversed.
Fixed
Fixes an issue where annotations with appearance stream could be rendered at the wrong position and/or size.
Fixed
Fixes an issue where annotations could be returned from the last page when forms are in the document, even if a different page was requested.
Fixed
Fixes an issue with the label parser when encountering offset pages.
Fixed
Fixes an issue where when trying to copy a webpage link in the internal web browser, the system could throw a NSInvalidArgumentException if the link was nil.

Changed
Next/Prev now works across multiple pages and also includes choice form elements.
Changed

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)

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.
Changed
The interactivePopGesture (new on iOS 7) is now disabled while we're drawing to prevent accidental usage.

The PSPDFViewController will now properly clean up state from the annotation creation when dropped from user code while the toolbar is in drawing mode.
Changed
The outline controller now properly shows page destinations above page 10.000.
Changed
Hides a harmless log warning when PSPDFKit tried to render an annotation with an empty width/height.

When undo is disabled, the undo/redo buttons are now properly hidden when leaving the drawing mode.
Changed
No longer draws the arrow when flattening choice form elements.
Changed
