Instance Method

unregisterForPreviewing(withContext:)

Unregisters a previously registered view controller identified by its context object.

Declaration

func unregisterForPreviewing(withContext previewing: UIViewControllerPreviewing)

Parameters

previewing

The context object that was returned when you registered the view controller by calling the registerForPreviewing(with:sourceView:) method.

Discussion

The system calls this method automatically when a 3D Touch-registered view controller is deallocated.

In some circumstances, you must explicitly call this method. This is the case if a registered view controller’s view hierarchy changes state, or if presenting a preview is otherwise no longer possible. In such cases, call this method.
