iOS6和MPMoviePlayerController - 黑色視圖

Question

我有一個MPMoviePlayerController播放視圖中嵌入視頻。這在iOS5/5.1等完美工作...但自升級到iOS6，這已停止工作，現在視圖只是黑色。有沒有人有任何想法或類似的問題？

Answer 1

嘗試這一個......

NSString *resourcePath = [[NSBundle mainBundle] pathForResource:@"ddd" ofType:@"mp4"]; 
NSURL *url = [NSURL fileURLWithPath:resourcePath]; 
MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:url]; 
moviePlayer.view.frame = CGRectMake(0, 0, 500, 500); 
moviePlayer.moviePlayer.shouldAutoplay=YES; 
moviePlayer.moviePlayer.controlStyle = MPMediaTypeMusicVideo; 
[moviePlayer.moviePlayer setFullscreen:YES animated:YES]; 
[self.view addSubview:moviePlayer.view]; 
[moviePlayer.moviePlayer play]; 

Answer 2

實際上，MPMediaTypeMusicVideo被定義爲MPMediaType，以下的定義是： MPMediaTypeMusicVideo = 1 < < 11，（2048）

這是無證件嗎？

我曾經訪問過相同的問題，最後發現重要行「[player prepareToPlay]」缺失。在iOS5中它沒有任何問題，但在iOS6中它導致黑屏;

MPMoviePlayerController *player = 
[[MPMoviePlayerController alloc] initWithContentURL: myURL]; 
[player prepareToPlay]; 
[player.view setFrame: myView.bounds]; // player's frame must match parent's 
[myView addSubview: player.view]; 
// ... 
[player play];
