MPMoviePlayerPlaybackDidFinishNotification未被调用

Question

在我的代码中，在单击TopBar上的nextbutton和backButton时，不会调用pl​​ayerPlayBackDidFinish。但它被称为当视频文件播放完成后，请帮助，如果有人知道...

我的代码如下。

MPMoviePlayerPlaybackDidFinishNotification

通知观察者，电影 播放完毕。受影响的电影 播放器存储在通知对象 的参数中。此 通知中的 用户信息字典包含 MPMoviePlayerPlaybackDidFinishReasonUserInfoKey 密钥，该密钥指示 回放完成的原因。由于错误，播放失败 时也会发送此通知 。

该通知那里的电影播放器​​显示在全屏模式下 不在的情况下 发送，用户点击 完成按钮。在这种情况下，当播放器跳出全屏模式的 时， 完成按钮会导致电影播放暂停 。如果你想 在你的代码中检测到这种情况，你应该监视其他通知 ，如 MPMoviePlayerDidExitFullscreenNotification。

确保你没有做任何不发送该通知

Answer 2

观察

[[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(movieDidExitFullscreen:) 
               name:MPMoviePlayerDidExitFullscreenNotification 
               object:nil]; 

并添加动作

- (IBAction) movieDidExitFullscreen:(NSNotification*)notification 
    { 
     NSLog(@"movieDidExitFullscreen"); 
     [self.moviePlayer stop]; 
     [self.moviePlayer setFullscreen:NO animated:NO]; 
     [self.moviePlayer.view removeFromSuperview]; 
    } 

Answer 3

我有类似的问题并发现了这个setti ng MPMoviePlayerController的repeatMode到MPMovieRepeatModeOne停止MPMoviePlayerPlaybackDidFinishNotification的发射，我必须为循环播放视频做些什么。

MPMoviePlayerController *moviePlayer =  [[MPMoviePlayerController alloc] initWithContentURL:video_url]; 
[moviePlayer setRepeatMode:MPMovieRepeatModeOne]; 

当我改变REPEATMODE到MPMovieRepeatModeNone，MPMoviePlayerPlaybackDidFinishNotification被正确地解雇了。
