Question

我有一个现有的iPhone / iPad通用应用程序，通过Wi-Fi（mp4）和3G网络（3gp）与MPMoviePlayerController一起流式传输视频。当iOS 4.3发布时，我们的4.3设备无法再通过3G网络播放3gp视频。我测试了一个本地3gp文件但也失败了，但是在运行4.2.x的3G手机上运行。

调试视图控制器后，我看到尝试在本地播放3gp文件或通过URL流式传输时未触发MPMoviePlayerLoadStateDidChangeNotification通知。

[APPDEL showStatusView:  @"Please wait..."];

    NSString * videoUrl = [[request.URL description] stringByReplacingOccurrencesOfString: @"idvideo:" withString: @"http:"];
    DLog(@"Loading video %@", videoUrl);
    _moviePlayer = [[IDMoviePlayerController alloc] initWithContentURL: [NSURL URLWithString: videoUrl]];
    _moviePlayer.view.backgroundColor = [UIColor clearColor];
    _moviePlayer.allowsAirPlay = YES;

    _moviePlayer.scalingMode = MPMovieScalingModeAspectFit;

    if ([_moviePlayer respondsToSelector:@selector(loadState)]) {
        // May help to reduce latency
        [_moviePlayer prepareToPlay];

        // Register that the load state changed (movie is ready)
        [[NSNotificationCenter defaultCenter] addObserver:self 
                                                                                         selector:@selector(moviePlayerLoadStateChanged:) 
                                                                                                 name:MPMoviePlayerLoadStateDidChangeNotification 
                                                                                             object:_moviePlayer];

        [[NSNotificationCenter defaultCenter] addObserver:self 
                                                 selector:@selector(moviePlayerPreloadDidFinish:) 
                                                     name:MPMoviePlayerContentPreloadDidFinishNotification
                                                   object:_moviePlayer];


        //[NSTimer scheduledTimerWithTimeInterval:3.0 target:self selector:@selector(moviePlayerTimerUp:) userInfo:nil repeats:NO];
    }  
    else {
        // Register to receive a notification when the movie is in memory and ready to play.
        [[NSNotificationCenter defaultCenter] addObserver:self 
                                                                                         selector:@selector(moviePreloadDidFinish:) 
                                                                                                 name:MPMoviePlayerLoadStateDidChangeNotification 
                                                                                             object:nil];
    }       

    [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(onMovieDone:) name: MPMoviePlayerPlaybackDidFinishNotification object: nil];

    if ([_moviePlayer respondsToSelector: @selector(view)]) {
        [self.view addSubview: _moviePlayer.view];

        if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
            _moviePlayer.controlStyle = MPMovieControlStyleEmbedded;
        }
        else {
            _moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
        }

        _moviePlayer.view.frame = _webView.frame;
    }

    [_moviePlayer play];

始终命中loadState的第一个条件。对于3gp文件，代码永远不会到达moviePlayerLoadStateChanged选择器方法，该方法隐藏指示符/状态视图并创建其他全屏/方向通知。指标/状态视图将保持不变并且纺纱。在调试器中，我可以看到onMovieDone选择器方法的触发时间远远超过视频真正完成的时间。

混淆。
