MPMoviePlayer 流式传输时自动暂停

Question

我正在使用 MPMoviePlayerViewController 从服务器播放视频流，其他一切正常。我的问题是，当我播放视频时，如果没有可用的可播放内容，它会自动播放并自动进入暂停状态，并且在加载内容后不播放。

movieController = [[MPMoviePlayerViewController alloc] init];
movieController.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
[movieController.moviePlayer setContentURL:mediaURL];
[movieController.moviePlayer prepareToPlay];
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:nil];
[movieController.moviePlayer setControlStyle:MPMovieControlStyleFullscreen];
[movieController.moviePlayer setFullscreen:YES];
[movieController.moviePlayer setShouldAutoplay:YES];
[movieController.moviePlayer play];
[self presentMoviePlayerViewControllerAnimated:movieController];

这是我的代码，用于播放 mediaURL 给出的 url 中的视频。我尝试添加 MPMoviePlayerPlaybackStateDidChangeNotification 以检查状态更改为 MPMoviePlaybackStatePaused，它也工作正常。还检查了 MPMovieLoadState 和 MPMovieLoadStatePlaythroughOK 使用 MPMoviePlayerLoadStateDidChangeNotification 问题是在暂停后不会自动获得 MPMovieLoadStatePlaythroughOK。This link

此外，除了 MPMoviePlayerPlaybackStateDidChangeNotification 之外，还有什么方法可以让暂停按钮点击，因为通知也会因其他原因而被触发。

我在 MPMoviePlayerViewController 中的默认 Play/Pause 按钮上方添加了一个透明按钮，如下所示。

CGRect frame = CGRectZero;
CGFloat width = 100, height= 50;
frame.origin.x = CGRectGetHeight(movieController.moviePlayer.view.frame)/2 - (width/2);
frame.origin.y = CGRectGetWidth(movieController.moviePlayer.view.frame) - height;
frame.size = CGSizeMake(width, height);
UIButton* playButton = [[UIButton alloc] initWithFrame:frame];
playButton.backgroundColor = [UIColor clearColor];
[playButton addTarget:self action:@selector(playButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
[movieController.moviePlayer.view addSubview:playButton];


- (void) playButtonTapped:(UIButton*) sender {
if (APP_DELEGATE.movieController.moviePlayer.playbackState == 1) {
    [APP_DELEGATE.movieController.moviePlayer pause];        
}
else if (APP_DELEGATE.movieController.moviePlayer.playbackState == 2)
{
    [APP_DELEGATE.movieController.moviePlayer play];        
}
}
