MPMoviePlayerController在图层上空白

Question

我需要在一层UIView上播放MPMoviePlayerController。但只有声音出来，没有视频。

theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
[theMovie prepareToPlay];

theMovie.view.frame = CGRectMake(0, 0, 200, 150);
[theMovie setControlStyle:MPMovieControlStyleDefault];
[theMovie setFullscreen:NO animated:YES];
 theMovie.shouldAutoplay = YES;
[theMovie setContentURL:movieURL];

[self addSubview:theMovie.view];
[theMovie play];

我只有黑屏，只有音频。这是因为我将UIView称为层而不是子视图？因为我的要求是将UIView称为图层。

Answer 1

看起来不错，请尝试添加：

 [_openingMovie setMovieSourceType:MPMovieSourceTypeStreaming];

希望这有帮助

修改

在设置SourceType之后尝试设置ContentURL，如下所示

moviePlayerController_ = [[MPMoviePlayerViewController alloc] init];
moviePlayerController_.movieSourceType = MPMovieSourceTypeStreaming;
[moviePlayerController_.moviePlayer setContentURL:url];
