我一直在试图弄清楚如何在我的电影视图顶部获得“播放符号”，以便用户只需按下它，视频就会开始播放。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;
}

【解决方案1】：

您可以为您的按钮创建一个 IBOutlet，或者您必须自己通过这样的代码添加播放按钮...（以便通过代码访问它。）

  // Add play button 
  playButton = [[UIButton alloc] initWithFrame:CGRectMake(53, 212, 214, 36)];    
  [playButton setBackgroundImage:[UIImage imageNamed:@"playButton.png"] forState:UIControlStateNormal];
  [playButton addTarget:self action:@selector(buttonPressed:) forControlEvents: UIControlEventTouchUpInside];    
  [[self view] addSubview:playButton];

一旦你完成了将电影播放器添加到视图中......你需要将播放按钮放在前面，就像......一样。

[self.view bringSubviewToFront:playButton];

记住，一旦你将电影播放器添加到视图中，就必须这样做......
