视频播放器不会停止加载

Question

我正在开发一个应用程序，我想在其中播放来自远程 HTTP URL 的 mp4 视频。这是我的代码：

// 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;

我可以从 NSLog 行验证视频是否存在并且可以在网络浏览器上播放。但是，播放器永远显示“加载”轮。如何让视频播放？

Answer 1

这行得通：

// 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];
