solved it:
解决了：
I turned my MPMoviePlayerController into a property:
我把我的 MPMoviePlayerController 变成了一个属性：
//add in header
//在标题中添加
@property (strong,nonatomic) MPMoviePlayerController *myPlayer;
//add in .m file
//添加.m文件
- (IBAction)playStream:(id)sender {
NSString *urlAddress = @"http://67.159.28.74:8730";
NSURL *url = [NSURL URLWithString:urlAddress];
MPMoviePlayerController *player = [[MPMoviePlayerController alloc]initWithContentURL:url];
[player prepareToPlay];
//Remember you have to add MediaPlayer.framework to your project
/*[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];*/
player.movieSourceType = MPMovieSourceTypeStreaming;
player.view.hidden = YES;
self.myPlayer = player;
[self.view addSubview:self.myPlayer.view];
if(player){
[self.myPlayer play];
}
}

You have to set a class variable like this:
你必须像这样设置一个类变量：
@property (nonatomic, retain) MPMoviePlayerController *moviePlayer;
My code looks like this:
我的代码如下所示：
NSURL *theUrl = [[NSBundle mainBundle] URLForResource:@"test" withExtension:@"mp4"];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:theUrl];
[moviePlayer prepareToPlay];
[moviePlayer.view setFrame: self.view.bounds];
moviePlayer.movieSourceType = MPMovieSourceTypeFile;
[self.view addSubview: moviePlayer.view];
[moviePlayer play];
This works perfect for me!
这对我来说非常适合！

on xCode 4.6.1 it worked fine.
在 xCode 4.6.1 上它运行良好。
But i had this problem with xCode 5!
但是我在使用 xCode 5 时遇到了这个问题！
But this solution is very helpful:
但是这个解决方案非常有帮助：
"The solution is that the player would have to be an instance variable or property of the view controller. ie We must use the instance of MPMoviePlayerController
“解决方案是播放器必须是视图控制器的实例变量或属性。即我们必须使用 MPMoviePlayerController 的实例
@property (nonatomic,strong) MPMoviePlayerController *myMovieController;"
@property (nonatomic,strong) MPMoviePlayerController *myMovieController;"
Thank author very much!
非常感谢作者！
And this is my code:
这是我的代码：
UIGraphicsBeginImageContext(CGSizeMake(1,1));
NSString *path = [[NSBundle mainBundle] pathForResource:@"video" ofType:@"mp4"];
NSURL *videoURL = [NSURL fileURLWithPath:path];
self.moviePlayerView = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
[self.moviePlayerView prepareToPlay];
[self.moviePlayerView.view setFrame:CGRectMake(0, 0, 320, self.view.frame.size.height/2)];
self.moviePlayerView.view.backgroundColor = [UIColor clearColor];
[self.moviePlayerView setContentURL:videoURL];
self.moviePlayerView.movieSourceType = MPMovieSourceTypeFile;
self.moviePlayerView.controlStyle = MPMovieControlStyleDefault;
[self.view addSubview:self.moviePlayerView.view];
self.moviePlayerView.shouldAutoplay = NO;
[self.moviePlayerView play];
UIGraphicsEndImageContext();

You can try to do this just after you instantiate your player:
[player prepareToPlay]
您可以在实例化播放器后尝试执行此操作：
[player prepareToPlay]

试试这个，它在 ios6 中对我很有效
NSString *resourcePath = [[NSBundle mainBundle] pathForResource:@"ddd" ofType:@"mp4"];
NSLog(@"%@",resourcePath);
NSURL *url = [NSURL fileURLWithPath:resourcePath];
NSLog(@"%@",url);
MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
moviePlayer.view.frame = self.view.frame;
moviePlayer.moviePlayer.shouldAutoplay=YES;
moviePlayer.moviePlayer.controlStyle = MPMovieControlStyleNone;
[moviePlayer.moviePlayer setFullscreen:YES animated:YES];
[self.view addSubview:moviePlayer.view];
[moviePlayer.moviePlayer play];

Here is an interesting line of code which you are missing.
这是您缺少的有趣代码行。
According to Apple's document
根据苹果的文件
" When you add a movie player's view to your app's view hierarchy, be sure to size the frame correctly, as shown here: http://tinyurl.com/9wgv9wc
" 当您将电影播放器的视图添加到应用程序的视图层次结构时，请确保正确调整框架的大小，如下所示：http: //tinyurl.com/9wgv9wc
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];

解决方案是玩家必须是视图控制器的实例变量或属性。即我们必须使用 MPMoviePlayerController 的实例
@property (nonatomic,strong) MPMoviePlayerController *myMovieController;
