Annoatation list

Annoations can be viewed as a list in this UI component

Annotation list

This tutorial only applies to Xamarin.iOS. See Xamarin.Android equivalent here.

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.

linkShow 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:

var annotationViewController = new pdftron.PDF.Controls.PTAnnotationViewController (mPdfViewCtrl);
annotationViewController.AnnotationViewControllerAnnotationSelected += (object sender, AnnotationViewControllerAnnotationSelectedEventArgs e) => {
    // perform custom action
    this.DismissViewController (true, null);
};
annotationViewController.AnnotationViewControllerDidCancel += (object sender, EventArgs e) => {
    this.DismissViewController (true, null);
};

var navigationController = new UINavigationController (annotationViewController);
if (UserInterfaceIdiomIsPad)
{
    navigationController.ModalPresentationStyle = UIModalPresentationStyle.Popover;
    navigationController.PopoverPresentationController.BarButtonItem = annotationListButton;
}

this.PresentViewController (navigationController, true, null);
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 PopoverPresentationController 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.)
