ios - 在 iOS sdk MPMoviePlayerController 中播放视频的问题

Question

我正在尝试在 iPhone 中播放视频，以下是我使用的代码。

它一直在加载，但视频无法播放，我是不是遗漏了什么。

播放器已启动，但它只显示加载并且从不播放视频。

我还导入了MediaPlayer/MediaPlayer.h

-(IBAction)play:(id)sender
{
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:@"test_output" ofType:@"mov"];


NSURL *url = [NSURL URLWithString:
             moviePath];

_moviePlayer =  [[MPMoviePlayerController alloc]
                 initWithContentURL:url];

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:_moviePlayer];
[_moviePlayer prepareToPlay];
_moviePlayer.controlStyle = MPMovieControlStyleDefault;
_moviePlayer.shouldAutoplay = YES;
[self.view addSubview:_moviePlayer.view];
[_moviePlayer setFullscreen:YES animated:YES];
     }


        - (void) moviePlayBackDidFinish:(NSNotification*)notification {
           MPMoviePlayerController *player = [notification object];
         [[NSNotificationCenter defaultCenter]
          removeObserver:self
          name:MPMoviePlayerPlaybackDidFinishNotification
          object:player];

if ([player
     respondsToSelector:@selector(setFullscreen:animated:)])
{
    [player.view removeFromSuperview];
}
 }

首先，检查您的电影文件是否已添加到您的项目中。

其次，尝试使用 fileURLWithPath 创建路径。替换您的以下代码

NSURL *url = [NSURL URLWithString:moviePath];

与

NSURL *url = [NSURL fileURLWithPath:moviePath];
