MPMoviePlayerController在启动前显示空白屏幕？

Question

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];

Answer 1

Also, you should make sure to set the movieSourceType on your MPMoviePlayercontroller (which you can access via moviePlayerViewController.moviePlayer ).

If you don't set this property, it defaults to MPMovieSourceTypeUnknown , and the player won't show controls until the request has returned (which can take a while on WWAN ).

Answer 2

First, you should be using this for display the movies:

[self presentMoviePlayerViewControllerAnimated:moviePlayerViewController];

Second, to change the moviePlayerViewController background you can use:

moviePlayerViewController.view.backgroundColor = [UIColor blackColor];

So when the video is launched the background color will be black.

Hope its helps...
