• Version: 8.1.0.76833
• Release Date: December 4th, 2020
• Built with Xcode 12.1 (12A7403)

The all-new UI is now out of beta, and is the default UI for the SDK.

The PTDocumentViewController class is deprecated in this release. For all new projects, the new PTDocumentController class should be used instead. The PTDocumentController class includes the updated annotation user interface with the PTToolGroupToolbar for a streamlined annotation workflow. Please see our migration guide for information on how to adopt the PTDocumentController class in your existing project.

In addition to the PTDocumentViewController class, the following classes are also deprecated:

• PTAnnotationToolbar
• PTCollaborationDocumentViewController

The PTTabbedDocumentViewController class now creates PTDocumentController instances by default for document tabs. This behavior can be controlled with the PTTabbedDocumentViewController.viewControllerClass instance property to use the deprecated PTDocumentViewController class or a custom subclass.

linkNew

• Adds an Apple Pencil interaction mode setting to the PTToolsSettingsManager to control how Apple Pencil and fingers are treated when creating annotations. The different modes for the new PTToolsSettingsManager.pencilInteractionMode setting are:

  • Apple Pencil and finger touches create annotations.
  • Apple Pencil touches create annotations, fingers pan and zoom.
  • The iOS Pencil system setting is obeyed.

  The default Apple Pencil interaction mode is to obey the iOS Pencil system setting on iOS 14 and above, and to accept Pencil and finger touches on iOS 13 and below.

• Shape annotations (rectangle, ellipse, line, arrow) can now be created with a single tap when the respective shape creation tool is active.
• App-wide settings in the PTToolsSettingsManager can now be accessed from the viewer via the appSettingsButtonItem. By default, this item is hidden. The appSettingsButtonHidden property can be used to show this item in the more-items list from the ellipsis button in the navigation bar.
• The magnification loupe will not be shown when creating text markup annotations with an Apple Pencil.
• It is now possible to specify the UIDatePickerStyle for form widgets which use a date picker. This can be controlled with the following API: PTWidgetAnnotationOptions.preferredDatePickerStyle.
