MPMoviePlayerViewController是苹果提供的播放视频的控制器，可以直接从当前的控制器中推出即可。

NSBundle *bundle = [NSBundle mainBundle];     NSString *moviePath = [bundle pathForResource:@"Movie" ofType:@"m4v"];     NSURL *movieURL = [NSURL fileURLWithPath:moviePath];     MPMoviePlayerViewController *moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];     moviePlayerViewController.moviePlayer.controlStyle =  MPMovieControlStyleFullscreen; [self  presentMoviePlayerViewControllerAnimated:moviePlayerViewController];
