Iphone 在滚动视图中发布

我有一个UIScrollView，需要在其中添加两个视频，但我面临以下问题：

*我有一个有两个页面的滚动视图。如果我只在第一个视频中添加一个，它工作正常。在滚动视图的第一个页面中，我将有视频，第二个将为空

*如果我尝试添加这两个视频，scrollView的第一页将为空，第二页将包含第二个视频

无论我怎么做，我都不能在scrollView中同时播放这两个视频

以下是我所做的：

 scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];


scrollView.pagingEnabled = YES;

NSString *path1 = [[NSBundle mainBundle] pathForResource:@"video1" ofType:@"mp4"];
NSString *path2 = [[NSBundle mainBundle] pathForResource:@"video2" ofType:@"mp4"];

videoPlayer1 = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:path1]];
videoPlayer2 = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:path2]];

[[videoPlayer1 view] setFrame:CGRectMake(0, 0, 320, 335)];
[videoPlayer1 prepareToPlay];


[videoPlayer1 setControlStyle:MPMovieControlStyleDefault];
videoPlayer1.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

[self.scrollView addSubview:[videoPlayer1 view]];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:videoPlayer1];

[[videoPlayer2 view] setFrame:CGRectMake(320, 0, 320, 335)];
[videoPlayer2 prepareToPlay];

[videoPlayer2 setControlStyle:MPMovieControlStyleDefault];
videoPlayer2.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

[self.scrollView addSubview:[videoPlayer2 view]];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:
 MPMoviePlayerPlaybackDidFinishNotification object:videoPlayer2];

scrollView.contentSize = CGSizeMake(640, 400);
[self.view addSubview:scrollView];

请帮忙，谢谢
