audio - 流音频时看不到MPMoviePlayerControls

Question

我仅流音频时看不到MPMoviePlayerController控件，这正常吗？我只能看到黑屏，尽管正在播放音频，但是在另一 View 中播放视频时它可以工作。我希望这将允许我使用控件，这样我就不必使用AVPlayer构建自己的UI。

我的代码如下:

self.audioPlayer = [[MPMoviePlayerController alloc] init];
self.audioPlayer.movieSourceType = MPMovieSourceTypeStreaming;
[self.audioPlayer setContentURL:self.audioUrl];
[self.audioPlayer setControlStyle:MPMovieControlModeDefault];
self.audioPlayer.scalingMode = MPMovieScalingModeAspectFit;


[self.audioPlayer.view setFrame:self.view.bounds];

[self.view addSubview:self.audioPlayer.view];
[self.view bringSubviewToFront:self.audioPlayer.view];

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:self.audioPlayer];

[self.audioPlayer prepareToPlay];
[self.audioPlayer play];

问候

Answer 1

最后，我使用UI构建了一个AVPlayer，而不是使用MPmovieplayer。
