 NSString *urlString =[NSString stringWithFormat:@"http://baidu.v.ifeng.com/kan/aIAX8?fr=v.baidu.com/"];

    NSURL *url =[NSURL URLWithString:urlString];

   NSURLRequest *request =[NSURLRequest requestWithURL:url];

   UIWebView *web =[[UIWebView alloc] initWithFrame:self.view.bounds];

    [web  loadRequest:request];

   [self.view addSubview:web];

 2//需要导入MediaPlayer.framework    和 #import <MediaPlayer/MediaPlayer.h>

还有不能直接在viewDidLoad 里面加载  或报错  层次混乱 view加载完毕 就调用mv present不好需要推迟最好加载完毕在调用

 MPMoviePlayerViewController *mv =[[MPMoviePlayerViewController alloc] initWithContentURL:url];

     mv.moviePlayer.scalingMode =MPMovieControlStyleEmbedded;

    [self presentMoviePlayerViewControllerAnimated:mv];
