iPhone - MPMoviePlayerController -播放音频时窗口不显示

Question

我正在尝试在MPMoviePlayerController中播放音频网址(流网址)。(我知道AVAudioFramework to play)。我想显示的视图与控件，用户可以暂停，播放，改变音量等与MPMoviePlayerController。这就是我使用MPMoviePlayerController的原因。音频正在播放，但我看不到媒体播放器。为什么？我使用了以下代码：

-(void)playMovie:(NSURL *)movieURL attachTo:(UIView*)parentView autoPlay:(BOOL)autoplay showControls:(BOOL)showcontrols repeat:(BOOL)autorepeat autoExit:(BOOL)exit
{
    moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
    moviePlayer.scalingMode = MPMovieScalingModeAspectFit;

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

    moviePlayer.controlStyle = showcontrols ? MPMovieControlStyleEmbedded : MPMovieControlStyleNone;
    moviePlayer.repeatMode = autorepeat;    
    moviePlayer.shouldAutoplay = autoplay;
    [moviePlayer play];
    [parentView addSubview:moviePlayer.view];
}

Answer 1

当使用MPMoviePlayerController播放音频时，它不会显示任何视图。只有视频，它才会显示一个视图。

Answer 2

我认为你需要设置电影播放器视图的帧：

moviePlayer.view.frame = parentView.bounds; // for example

如果您更喜欢全屏显示，请使用：

[moviePlayer setFullscreen:YES animated:YES];

(并删除[parentView addSubview:moviePlayer.view])
