当我尝试从我的iPhone(位于documentsDirectory)中播放视频时,使用iOS 5时出现以下错误,而iOS 4.3正常工作时:

AVPlayerItem类的实例0x168da0已取消分配,而键值观察者仍在其中注册.观察信息被泄露,甚至可能被错误地附加到其他物体上.在NSKVODeallocateBreak上设置断点以在调试器中停止.这是当前的观察信息:(上下文:0x0,属性:0x10b570>上下文:0x0,属性:0x117ab0>

这是代码提取:

MPMoviePlayerController *moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:[appDelegate.mediaManager loadVideo:[element valueForAttributeNamed:@"value"]]];  

        //create a NSNotificationCenter which call moviePlaybackComplete function when video playback finished
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlaybackComplete:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayerController];  

        //display the moviePlayer view
        [self.view addSubview:moviePlayerController.view];
        moviePlayerController.fullscreen = YES;  
        [moviePlayerController play];
