Integrate the new Viewer UI

If you are migrating from an existing implementation, please see the migration guide.

Single document viewer

Follow the existing guides, using a PTDocumentController instead of a PTDocumentViewController.

Tabbed document viewer

Create a PTTabbedDocumentViewController as described in the guides, and then set its viewControllerClass property to the PTDocumentController class:

Swift

tabbedDocumentViewController.viewControllerClass = PTDocumentController.self
