PDFTron is now Apryse, learn more here.

Version Changelog (January 31st, 2019)

  • Version:
  • Release Date: January 31st, 2019
  • Built with Xcode 10.1 (10B61)


  • A new full text search control PTTextSearchViewController that is integrated into PTDocumentViewController.
  • Classes that are used internally by the PTDocumentViewController and PTTabbedDocumentViewController can now be subclassed. In this release it is possible to subclass the PTDocumentViewControllers that are created by the PTTabbedDocumentViewController, as well as any class that inherits from PTTool (the annotation interaction tools). (More classes will be added in future releases.) At this time only concrete classes are supported. Example usage:
PTOverrides.overrideClass(PTDocumentViewController.self, withClass: EGDocumentViewController.self);
  • Form filling events now create notifications (in addition to the existing delegate methods). Example usage:
NotificationCenter.default.addObserver(self, selector: #selector(self.formFieldModified(_:)), name: PTToolManagerFormFieldDataModifiedNotification, object: documentViewController.toolManager)
  • A number of previously internal classes are now exposed on the PTDocumentViewController:
    • PTAnnotationToolbar
    • PTTextSearchViewController
    • PTPageIndicatorViewController
    • PTSettingsViewController
    • PTReflowViewController
  • PTAnnotationToolbar now has a new API (precedenceArray) to allow changing which buttons are visible for different size toolbars.
  • A number of updated documentation guides:

Bug fixes

  • PTPDFViewCtrl's openUrlAsync: will no longer crash when repeatedly called multiple times in quick succession.
  • A number of miscellaneous minor bug fixes.

API diff

  • PT class prefixes have been added to all Tools.framework classes that were previously missing them.

  • The PTToolManager annotation permission objects have been deprecated and renamed to option objects, e.g. squareAnnotationPermission to squareAnnotationOptions.

  • An API diff from the previous version is available.
