Responding to Opening Events

The PTDocumentViewController shows a PDF viewer and annotator complete with controls such as an annotation toolbar, page layout controls, bookmarks, thumbnail viewer, etc. All of its component pieces are part of the Tools framework, and this class packages them into one easy to use view controller.

For a version of PTDocumentViewController that supports multiple documents, see PTTabbedDocumentViewController.

The document viewer includes a toolbar at the top and quick scroller at the bottom.

The document view control is part of the Tools library, so make sure you have added the Tools library to your project.

The following shows how to create a document viewer, set the document to display, and present it on screen.

let documentController = PTDocumentViewController()

// The PTDocumentViewController must be in a navigation controller before a document can be opened
let navigationController = UINavigationController(rootViewController: documentController)

// Open an existing local file URL.
let fileURL: URL! = Bundle.main.url(forResource: "sample", withExtension: "pdf")

documentController.openDocument(with: fileURL)

// Show navigation (and document) controller.
self.present(navigationController, animated: true, completion: nil)
