PSPDFKit

• API
  The distinction between standard stamps and custom text stamps has been clarified with the following deprecations and replacements. If you previously used the stamp subject consider whether you want a standard or custom text stamp. For standard stamps, subject has been deprecated in favor of stampType and the value of this property should usually be one of the values defined by the new PSPDFStampType string enum. PSPDFKit will provide the localized title for standard stamps. localizedSubject has been deprecated in favor of title. Set the title instead of stampType for custom text stamps, where you provide a title that has already been localized or user-generated. subtext has been deprecated in favor of subtitle. (#15895)

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

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. Since PSPDFKit doesn’t own the application, yet this requires hooks to your app delegate, the previous implementation was flawed and subsequently removed.
• Changed
