The methods of the
UIPopover protocol let you customize the behavior of a popover-based presentation. A popover presentation controller notifies your delegate at appropriate points during the presentation process. You can use the delegate methods to customize this process and respond to changes dynamically.
- iOS 8.0+
After defining an object that adopts this protocol, assign that object to the
delegate property of a
UIPopover object. You must present a view controller using the
popover style before you can obtain such an object. For more information about popover presentation controllers, see
