objective-c - 如何使用 MPMoviePlayerController 播放视频

Question

我正在使用此代码播放来自苹果网站的视频流

- (IBAction)playMovie:(UIButton *)sender {
    NSLog(@"start playing");
    //NSURL *url = [NSURL URLWithString:@"http://spatie.be/test.mov"];
    NSURL *url = [NSURL URLWithString:@"http://stream.qtv.apple.com/events/mar/123pibhargjknawdconwecown/12oihbqeorvfhbpiubqnfv3_650_ref.mov"];
    moviePlayer =  [[MPMoviePlayerController alloc]
                    initWithContentURL:url];


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

    moviePlayer.controlStyle = MPMovieControlStyleDefault;
    moviePlayer.shouldAutoplay = YES;
    moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
    [self.view addSubview:moviePlayer.view];
    [moviePlayer setFullscreen:YES animated:YES];    
}
- (void) moviePlayBackDidFinish:(NSNotification*)notification {

    NSError *error = [[notification userInfo] objectForKey:@"error"];
    if (error) {
        NSLog(@"Did finish with error: %@", error);
    }    

    MPMoviePlayerController *player = [notification object];
    [[NSNotificationCenter defaultCenter] 
     removeObserver:self
     name:MPMoviePlayerPlaybackDidFinishNotification
     object:player];

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

}

调用 playMovie 时，立即调用 moviePlayBackDidFinish 并记录错误消息:

Did finish with error: Error Domain=MediaPlayerErrorDomain Code=-11800 "The operation could not be completed" UserInfo=0x78d25d0 {NSLocalizedDescription=The operation could not be completed}

我该如何解决这个错误？

您没有将此标记为 iOS，但 MPMoviePlayer 仅适用于 iOS。这应该适用于将在 iOS 上播放的视频。很遗憾，您尝试播放的视频与 iOS 不兼容。试试这个网址:
