A specialized view controller that provides a graphical interface for selecting media items.
An MPMediaPickerController object, or media item picker, is a specialized view controller that you employ to provide a graphical interface for selecting media items. To display a media item picker, present it modally on an existing view controller. Presenting an MPMediaPickerController in non-modal mode; for example, pushing a MPMediaPickerController onto an existing UINavigationController stack will cause your app to crash. Media items are described in MPMediaItem.
