媒体播放器- iPhone - MPMoviePlayerController语言 - 窗口不显示播放音频

Question

我试图在MPMoviePlayerController中播放音频URL(流媒体URL)。(我知道avaudiframework要玩)。我想用MPMoviePlayerController显示带有用户可以暂停，播放，改变音量等控件的视图。这就是我使用MPMoviePlayerController的原因。音频正在播放，但我没有看到媒体播放器。为什么?我使用下面的代码:

-(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

我认为你需要设置电影播放器视图的框架:

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

如果你喜欢全屏显示，使用:

[moviePlayer setFullscreen:YES animated:YES];

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

Answer 2

当使用MPMoviePlayerController播放音频时，它不会显示任何视图。
