Display outlines & bookmarks on iOS

A document outline, or table of contents, demonstrates how the PDF document is organized and helps users see the overall picture. The PTOutlineViewController class shows the document outline (table of contents) that can be used to navigate through the document being viewed by a PTPDFViewCtrl by tapping on a bookmark item.

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

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

// Initialize outline view controller with a PTPDFViewCtrl instance.
let outlineViewController = PTOutlineViewController(pdfViewCtrl: pdfViewCtrl)

// Set the current view controller as the outline view controller's delegate.
outlineViewController.delegate = self

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

self.present(navigationController, animated: true, completion: nil)

You can set a delegate to be notified by the outline view controller when outline bookmarks are selected with the PTOutlineViewControllerDelegate protocol. (See the CompleteReader example for usage of an PTOutlineViewController.)
