View annotations as list on iOS

The PTAnnotationViewController class shows a list of all annotations in a document being viewed by a PTPDFViewCtrl. The list contains any comments that have been added to the annotations.

Annotation view controller

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

Show an annotation view controller

To create a new annotation view controller instance and display it from another view controller, supply a PTPDFViewCtrl instance to the PTAnnotationViewController designated initializer:

// Initialize annotation view controller with a PTPDFViewCtrl instance.
let annotationViewController = PTAnnotationViewController(pdfViewCtrl: pdfViewCtrl)

// Set the current view controller as the annotation view controller's delegate.
annotationViewController.delegate = self

let navigationController = UINavigationController(rootViewController: annotationViewController)
if ( UIDevice.current.userInterfaceIdiom == .pad ) {
    navigationController.modalPresentationStyle = .popover
    navigationController.popoverPresentationController?.barButtonItem = annotationListButton

self.present(navigationController, animated: true, completion: nil)
The annotation view controller must be pushed onto a navigation controller's stack before being shown.
Presenting on iPads:
The annotation view controller is designed to be presented in a popover on iPads. To do so, you must provide the PTAnnotationViewController's UIPopoverPresentationController with either: OR as in the example above.

You can set a delegate to be notified by the annotation view controller when annotations are selected with the PTAnnotationViewControllerDelegate protocol. (See the CompleteReader sample for usage of the PTAnnotationViewController.)
