MPMoviePlayerViewController不显示仅在iPhone5中工作的视频音频

Question

在MPMoviePlayerViewController中，只有音频有效，但视频未显示。它适用于iphone 4和ios 7的iphone 4,4s等。

     NSURL *movieURL = [NSURL URLWithString:@"https://examplevideo.mp4"];
    self.playercontroller = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
    [self.playercontroller.view setFrame:CGRectMake(0, 0, 320, 320)];
     self.playercontroller.contentURL = movieURL;
    [self.view addSubview:self.playercontroller.view];
   [self.playercontroller play];

Answer 1

将视图添加到[self.playercontroller play]后，您应尝试致电self.view，而不是之前。
