  下面的代码非常适合我的应用程序 . 希望它会为你做同样的事情 . 主要是设置mpMoviePlayerController框架的框架 . 如果你不这样做，它几乎不会显示视频 .

  - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
      [[UIApplication sharedApplication] setStatusBarHidden:YES];
  
      // Register to receive a notification when the movie has finished playing. 
      [[NSNotificationCenter defaultCenter] addObserver:self 
                                               selector:@selector(moviePlayBackDidFinish:) 
                                                   name:MPMoviePlayerPlaybackDidFinishNotification 
                                                 object:nil];
  
      // Register to receive a notification when the movie scaling mode has changed. 
      [[NSNotificationCenter defaultCenter] addObserver:self 
                                               selector:@selector(movieScalingModeDidChange:) 
                                                   name:MPMoviePlayerScalingModeDidChangeNotification 
                                                 object:nil];
      kDomain = [NSString stringWithString:@"http://www.virtua-book.com/"];
      [navigationController setNavigationBarHidden:YES];
  
      NSURL *ur=[[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:@"IPAD" ofType:@"mp4"]];
      mpMCtr=[[MPMoviePlayerController alloc] initWithContentURL:ur];
      mpMCtr.fullscreen=YES;
      [mpMCtr setScalingMode:MPMovieScalingModeFill];
      [mpMCtr setShouldAutoplay:YES];
      [mpMCtr setControlStyle:MPMovieControlStyleNone];
      [mpMCtr setMovieSourceType:MPMovieSourceTypeFile];
      mpMCtr.view.frame = CGRectMake(0, 0, 1024, 768);
      [mpMCtr setRepeatMode:MPMovieRepeatModeNone];
  
      [mpMCtr play];
  
      [ur release];
  
      // Override point for customization after app launch    
      [navigationController.view addSubview:mpMCtr.view];
      [window addSubview:[navigationController view]];
      [window makeKeyAndVisible];
  
      return YES;
  }
  
  
  //  Notification called when the movie finished playing.
  - (void) moviePlayBackDidFinish:(NSNotification*)notification
  {
      [mpMCtr.view removeFromSuperview];
  }

  要修复后退/前进（或上一个/下一个）按钮，您应该执行以下操作：

  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayerPlaybackStateDidChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:nil];
  
  ...
  
  - (void) moviePlayerPlaybackStateDidChange: (NSNotification *) notification {
   if (moviePlayer.playbackState == MPMoviePlaybackStateStopped) {
    [moviePlayer setContentURL:[moviePlayer contentURL]];
    [moviePlayer play];
   }
  }

  沿着这些方向的东西可能是你想要做的：

  MPMoviePlayerViewController *mpvc = [[MPMoviePlayerViewController alloc] initWithContentUrl:movieUrl];
  [self presentMoviePlayerViewController:mpvc];

  MPMoviePlayerViewController *mp = [[MPMoviePlayerViewController alloc]initWithContentURL:movieURL];
  mp.moviePlayer.controlStyle = 2;

  好吧，伙计们，我发现这个：已被弃用了 .

  解决方案是 multimediaPlayer.controlStyle = MPMovieControlStyleDefault; 但它仍然无法正常工作 .
