通知观察者电影
已完成播放。受影响的电影
播放器存储在通知的对象
参数中。此
通知的
userInfo字典包含
MPMoviePlayerPlaybackDidFinishReasonUserInfoKey
键，表示
播放完成的原因。当播放因错误而导致
失败时，也会发送此通知
。
Notifies observers that the movie finished playing. The affected movie player is stored in the object parameter of the notification. The userInfo dictionary of this notification contains the MPMoviePlayerPlaybackDidFinishReasonUserInfoKey key, which indicates the reason that playback finished. This notification is also sent when playback fails because of an error.
如果电影
，则不会发送此通知播放器在全屏模式下显示
，用户点击完成按钮
。在这种情况下，
完成按钮会导致电影播放暂停，然后播放器转换为全屏模式的
。如果你想在你的代码中检测
这种情况，你
应该监控其他通知
，例如
MPMoviePlayerDidExitFullscreenNotification。
This notification is not sent in cases where the movie player is displaying in fullscreen mode and the user taps the Done button. In that instance, the Done button causes movie playback to pause while the player transitions out of fullscreen mode. If you want to detect this scenario in your code, you should monitor other notifications such as MPMoviePlayerDidExitFullscreenNotification.
确保您没有做任何未发送此通知的事情
Make sure that you are not doing anything that does not sent this notification
