A presentation style where the content is displayed over another view controller’s content.
- iOS 3.2+
- tvOS 9.0+
Using this presentation style, the current view controller's content is displayed over the view controller whose
defines property is
true. UIKit may walk up the view controller hierarchy to find a view controller that wants to define the presentation context. The views belonging to the presenting view controller are removed after the presentation completes.
When presenting a view controller in a popover, this presentation style is supported only if the transition style is
cover. Attempting to use a different transition style triggers an exception. However, you may use other transition styles (except the partial curl transition) if the parent view controller is not in a popover.
