How to play video stream with MPMoviePlayerController in iOS
提问by derFalke
I am trying to play a video stream from the internet on the iPhone by pressing a button. I used many code samples but nothing worked. With this code it opens a black view without any video stream or controls in it. (The stream itself works.)
我正在尝试通过按下按钮在 iPhone 上播放来自互联网的视频流。我使用了许多代码示例，但没有任何效果。使用此代码，它会打开一个黑色视图，其中没有任何视频流或控件。（流本身有效。）
NSURL *url = [NSURL URLWithString:@"http://MyStreamURL.com"];
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayer];
moviePlayer.controlStyle = MPMovieControlStyleDefault;
moviePlayer.shouldAutoplay = YES;
[self.view addSubview:moviePlayer.view];
[moviePlayer setFullscreen:YES animated:YES];

Instead of creating a MPMoviePlayerControllerand adding that to your view, it is probably simpler to create a MPMoviePlayerViewControllerand present that view controller modally (since you are trying to show your video full screen anyway). Then the MPMoviePlayerViewController can manage the presentation of your video for you.
与其创建 aMPMoviePlayerController并将其添加到您的视图中，不如创建 aMPMoviePlayerViewController并以模态方式呈现该视图控制器可能更简单（因为无论如何您都试图全屏显示视频）。然后 MPMoviePlayerViewController 可以为您管理视频的演示。
MPMoviePlayerViewController *mpvc = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(moviePlaybackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
mpvc.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
[self presentMoviePlayerViewControllerAnimated:mpvc];
[mpvc release];
In your moviePlayBackDidFinishdelegate method you can then dismiss the model view controller.
在您的moviePlayBackDidFinish委托方法中，您可以关闭模型视图控制器。

just add "MPMovieSourceTypeStreaming" to "moviesourcetype"
只需将“ MPMovieSourceTypeStreaming”添加到“ moviesourcetype”
