当没有互联网连接时，dismissModalViewController不工作MPMoviePlayerViewController

Question

我有使用presentModalViewController:animated:调用的MPMoviePlayerViewController。当出现错误（无法连接互联网）时，我想解雇它。但是，dismissModalViewController在这种情况下似乎不起作用。

- (void)movieFinishedCallback:(NSNotification*)aNotification 
{  
    NSLog(@"MOVIE FINISH CALL"); 

    // Obtain the reason why the movie playback finished 
    NSNumber *finishReason = [[aNotification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];  
    // Dismiss the view controller ONLY when the reason is not "playback ended" 

    if ([finishReason intValue] != MPMovieFinishReasonPlaybackEnded) 
    {  

     NSlog(@"Check go here"); 
     MPMoviePlayerController *moviePlayer = [aNotification object];  
     [[NSNotificationCenter defaultCenter] removeObserver:self 
                 name:MPMoviePlayerPlaybackDidFinishNotification 
                 object:moviePlayer];   
     [self dismissModalViewControllerAnimated:YES]; 
    } 
    else{ 
     [self dismissModalViewControllerAnimated:YES];   
    } 
} 



- (void)playPodcastRadio:(NSString *) urlRadio 
{ 
    // Initialize the movie player view controller with a video URL string 

    MPMoviePlayerViewController* mediaPlayer = [[MPMoviePlayerViewController alloc]initWithContentURL:[NSURL URLWithString:urlRadio]]; 
    mediaPlayer.moviePlayer.movieSourceType = MPMovieSourceTypeUnknown; 

    [[NSNotificationCenter defaultCenter] removeObserver:mediaPlayer name:MPMoviePlayerPlaybackDidFinishNotification object:mediaPlayer.moviePlayer]; 

    // Register this class as an observer instead  
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieFinishedCallback:) name:MPMoviePlayerPlaybackDidFinishNotification object:mediaPlayer.moviePlayer]; 

    mediaPlayer.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; 
    // Present the movie player view controller  
    [self presentModalViewController:mediaPlayer animated:YES]; 

    [mediaPlayer.moviePlayer prepareToPlay]; 
    [mediaPlayer.moviePlayer play]; 
} 

通知处理程序被调用并到达Check go here日志。但它不会消除modalViewController。 任何人都可以帮助我？

谢谢

它发生在iOS 4.3和iOS 5

不知道，如果你还在寻找答案。 每个苹果文档：http://developer.apple.com/library/ios/#documentation/MediaPlayer/Reference/MPMoviePlayerViewController_class/Reference/Reference.html#//apple_ref/occ/cl/MPMoviePlayerViewController

“要关闭模态播放的电影播放器​​视图控制器，请调用dismissMoviePlayerViewControllerAnimated方法。”
