Overview

The UIVideoEditorControllerDelegate protocol defines methods that your delegate object must implement to respond to the video editor. The methods of this protocol notify your delegate when the system has saved an edited movie or the user has cancelled editing to discard any changes. There is also a method for responding to errors encountered by the video editor.

The delegate methods are responsible for dismissing the video editor when the operation completes. To dismiss the editor, call the dismissModalViewControllerAnimated: method of the parent controller responsible for displaying the video editor. The video editor is described in UIVideoEditorController Class Reference.
