PSPDFKit and PSPDFKitUI now also come with a stable module interface. This enables linking with PSPDFKit frameworks, even if the Swift compiler version used in your application differs from the one we used to build the frameworks.

This release has some smaller breaking API changes. Please see our migration guide for details.

PSPDFKitUI

• API
  Deprecates the constants used as options in SpeechController API in favor of new constants of type SpeechController.Option. (#24223)

• Added
  Adds explanatory text at the bottom of PDFDocumentSecurityViewController when SDK.Setting.honorDocumentPermissions is disabled to clarify that restricting permissions will not change behavior in the app. To hide this message, use setLocalizationDictionary or setLocalizationClosure to use an empty string for the key DocumentSecurity_PermissionsDisabledExplanation. (#23857)
• Added
  Adds showing the annotation inspector’s color preset reset menu immediately in response a secondary click on a trackpad or mouse. This enhancement requires UIApplicationSupportsIndirectInputEvents to be enabled in your app’s Info.plist. (#23878)

• Removed
  Removes the localized strings entry with the key Squiggle, which was not used. The localized text for the squiggly annotation type has changed to ‘Squiggle’ using the key Squiggly as before. The best way to get this localized string key is to use the constant PSPDFAnnotationStringSquiggly. (#22861)

See the announcement post.

In preparation for iOS 12, this version of PSPDFKit now drops support for iOS 9. It also requires and is built with Xcode 9.4 (9F1027a). The new Image Documents component, which enables you to keep PSPDFImageDocuments editable even after saving, requires an updated license.

We prepared a migration guide to help you with some of the API changes in this version.

PSPDFKitUI

• Changed
  Improves state restoration to restore and persist selected annotations. (#14935)
• Changed
  Improves support for Dynamic Type, particularly for larger accessibility sizes. (#14788)
• Changed

(#13834)

Examples

• Added
  Adds a PSPDFKit Catalog example illustrating how to use a custom bookmark provider. (#15105)

7.5.1 - 25 Apr 2018

PSPDFKitUI

• Added
  Adds a signer subclassing hook to PSPDFSignatureViewController, enabling setting the certificate used for digital signing programmatically. This makes it possible to only allow the user to create a digital signature, instead of an ink signature. (#14846)

• API
  Removes the tapGesture property on PSPDFNoteAnnotationViewController and the class no longer conforms to UIGestureRecognizerDelegate. (#5721)
• API
  PSPDFPageView is no longer guaranteed to conform to PSPDFNoteAnnotationViewControllerDelegate. (#5721)
• 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
  Adds support for -[PSPDFConfiguration scrollOnTapPageEndEnabled] in page curl layouts. (#13302)
• Changed
  Improves PSPDFPageModeAutomatic behavior in connection with PSPDFPageTransitionScrollContinuous. This now always prefers single pages to take better use of the available screen real estate. (#14822)
• Changed
  Improves the layout of the search view controller on devices with bottom safe area insets. (#12969)
• Changed
  Improves type safety by removing the __kindof type annotation from -[PSPDFDrawView annotations], -[PSPDFPageView passthroughViewsForPopoverController], and -[PSPDFPageView selectedAnnotations]. This only affects Objective-C. (#14490)
• Changed
  Changing page by tapping on page edges is now disabled by default. To enable this, change PSPDFConfiguration.scrollOnTapPageEndEnabled to YES. (#14418)
• Changed

• Changed
  Ensures that the optional analytics provider tracks log deletion for all cases. (#14817)

  Removes ellipses in menu items (UIMenuItem) because there is no standard convention for this on iOS and space can be scarce. For example ‘Inspector…’ is now ‘Inspector’. (#14235)
• Fixed
  Fixes an issue that could result in a crash when the size class changes while in a page curl layout. (#14555)
• Fixed
  Fixes an issue that makes the page curl left or right align pages even though it is in single page mode. (#14555)
• Fixed
  Fixes an issue that triggered a page change animation in page curl in some cases even though the page was already visible. (#14528)
• Fixed

• API
  Renames PSPDFSignatureHashAlgorithmSHA386 to PSPDFSignatureHashAlgorithmSHA384 which is actually the correct name. (#13932)
• API
  tryLoadAnnotationsFromFileWithError: has been removed from PSPDFFileAnnotationProvider. Use loadAnnotationsWithError: instead to customize annotation loading. (#14570)
• API
  Deprecates PSPDFTextBlock.glyphs, PSPDFWord.glyphs, and PSPDFSelectionState.selectedGlyphs in favor of NSRange-based APIs. (#14606)
• 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)
• Added
  Adds createdAt, updatedAt and creatorName to Instant JSON. (#14443)
• Added

• Changed
  Removing an annotation with removeAnnotations:options: on PSPDFAnnotationManager or PSPDFDocument now also removes replies to that annotation. (#14385)
• 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)

• Fixed
  Fixes pages not being centered when zooming is disabled in landscape. (#14091)

Instant

• Changed
  Improves type safety by removing the __kindof type annotation from -[PSPDFInstantDocumentDescriptor annotationWithIdentifier:forDocument:error:]. This only affects Objective-C. (#14490)

Examples

• Added
  Adds PSPDFKit Catalog example illustrating how to rotate pages in 90 degree steps. (#14445)

• Fixed
  Fixes an issue where the deletion of an annotation could not be undone properly. 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)

    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

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.
