視頻播放器不停止加載

Question

我正在開發一個應用程序，我想從遠程HTTP URL播放mp4視頻。這裏是我的代碼：

// Prepare URL 
NSString *urlString = [NSString stringWithFormat:@"http://static.winterlightfilms.com/%@/film.mp4", responseObject]; 
NSLog(urlString); 
NSURL *url = [NSURL URLWithString:urlString]; 

MPMoviePlayerController *moviePlayer=[[MPMoviePlayerController alloc] init]; 

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer]; 

moviePlayer.controlStyle=MPMovieControlStyleDefault; 
moviePlayer.shouldAutoplay=NO; 
[self.view addSubview:moviePlayer.view]; 
[moviePlayer setFullscreen:YES animated:YES]; 
[moviePlayer setContentURL:url]; 
moviePlayer.shouldAutoplay=YES; 

我可以從視頻中存在的NSLog行驗證，它是在Web瀏覽器上播放。然而，玩家永遠顯示「加載」輪。我怎樣才能播放視頻？

這工作：

// Prepare URL 
NSString *urlString = [NSString stringWithFormat:@"http://static.winterlightfilms.com/%@/film.mp4", responseObject]; 
NSLog(urlString); 
NSURL *url = [NSURL URLWithString:urlString]; 

MPMoviePlayerViewController *mpvc = [[MPMoviePlayerViewController alloc] init]; 
mpvc.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming; 
[mpvc.moviePlayer setContentURL:url]; 

[self presentMoviePlayerViewControllerAnimated:mpvc];
