MPMoviePlayerController在启动前显示空白屏幕？
问题描述：
我有一个MPMoviePlayerController，我以模态方式呈现。视频加载正常，但是在视频启动之前，屏幕变为白色，直到加载完毕。如何防止这种情况发生？
I have an MPMoviePlayerController that I am presenting modally. The video loads fine, however just before the video is launched the screen turns white until it has loaded. How can I prevent this from happening?
moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:mySTVideo.video_url]];
[self presentModalViewController:moviePlayerViewController animated:YES];
答
首先，你应该用它来显示电影：
First, you should be using this for display the movies:
[self presentMoviePlayerViewControllerAnimated:moviePlayerViewController];
其次，要更改moviePlayerViewController背景，您可以使用：
Second, to change the moviePlayerViewController background you can use:
moviePlayerViewController.view.backgroundColor = [UIColor blackColor];
因此，当视频启动时，背景颜色将为黑色。
So when the video is launched the background color will be black.
