iOS6和MPMoviePlayerController - 黑色视图

Question

我有一个MPMoviePlayerController，它可以播放View中嵌入的视频。这在iOS5 / 5.1等上完美运行......但是自从升级到iOS6后，这已停止工作，现在视图只是黑色。有没有人有任何想法或类似问题？

Answer 1

试试这个......

NSString *resourcePath = [[NSBundle mainBundle] pathForResource:@"ddd" ofType:@"mp4"];
NSURL *url = [NSURL fileURLWithPath:resourcePath];
MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
moviePlayer.view.frame = CGRectMake(0, 0, 500, 500);
moviePlayer.moviePlayer.shouldAutoplay=YES;
moviePlayer.moviePlayer.controlStyle = MPMediaTypeMusicVideo;
[moviePlayer.moviePlayer setFullscreen:YES animated:YES];
[self.view addSubview:moviePlayer.view];
[moviePlayer.moviePlayer play];

Answer 2

我访问了同样的问题，最后发现关键行“[player prepareToPlay]”丢失了。在iOS5中它没有关系，但在iOS6中它会导致黑屏;

MPMoviePlayerController *player =
[[MPMoviePlayerController alloc] initWithContentURL: myURL];
[player prepareToPlay];
[player.view setFrame: myView.bounds];  // player's frame must match parent's
[myView addSubview: player.view];
// ...
[player play];

实际上，MPMediaTypeMusicVideo被定义为MPMediaType，下面是定义：    MPMediaTypeMusicVideo = 1＆lt;＆lt; 11，（2048）

这是无证件吗？
