Objective c 电影播放器iOS5在视图上播放符号

我一直在想如何在我的电影视图上添加“播放符号”，这样用户只需按下该按钮，视频就可以开始了。有人知道如何实现吗

-(void)viewDidLoad
{
//Video player
NSString *url = [[NSBundle mainBundle] pathForResource:self.navigationItem.title ofType:@"mov"];

_player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath: url]];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playerPlaybackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:_player];
_player.view.frame = CGRectMake( 350, 200, 400, 400);
[self.view addSubview:_player.view];
}

//Plays the movie once the "Play" button is pressed 
-(IBAction)playMovie
{
[_player play];
}

//Exits fullscreen when movie is finished
- (void) playerPlaybackDidFinish:(NSNotification*)notification
{
_player.fullscreen = NO;
}

你可以为你的按钮创建一个IBOutlet，或者你必须自己通过这样的代码添加播放按钮。。。（以便通过代码访问。）

一旦你把电影播放器添加到视图中。。。。你需要把播放按钮放在前面，就像

[self.view bringSubviewToFront:playButton];

请记住，一旦您将电影播放器添加到视图中，就要执行此操作
