如何创建一个按钮作为MPMoviePlayerController的子视图？

Question

我想添加一个自定义播放按钮，但不能把它放在视频前面。这是我的代码。

- (IBAction)playMovie:(UIButton *)sender { 


    NSURL *url = [[NSURL alloc] initWithString:urlStr.text]; 
    self.movie = [[MPMoviePlayerController alloc]initWithContentURL:url]; 
    self.movie.controlStyle = MPMovieControlStyleNone; 


    UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0,0,self.view.frame.size.width,self.view.frame.size.height)]; 
    button.backgroundColor=[UIColor yellowColor]; 
    [button setTitle:@"Normal State Title" forState:UIControlStateNormal]; 

    [movie.view addSubview:button]; 

    self.movie.shouldAutoplay = YES; 
    [self.view addSubview:self.movie.view]; 
    [self.movie setFullscreen:YES animated:NO]; 
}

我认为这是你在找什么。这是一个简单的例子。

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view, typically from a nib. 

    url=[NSURL URLWithString:@"https://scontent.cdninstagram.com/hphotos-xaf1/t50.2886-16/11179443_819874424728492_389701720_n.mp4"]; 

    movPlayer=[[MPMoviePlayerController alloc] init]; 
    [movPlayer setContentURL:url]; 
    [movPlayer setMovieSourceType:MPMovieSourceTypeFile]; 
    [movPlayer.view setFrame:CGRectMake(_imgVw.frame.origin.x, _imgVw.frame.origin.y, _imgVw.frame.size.width, _imgVw.frame.size.height)]; 
    [movPlayer prepareToPlay]; 
    movPlayer.controlStyle = MPMovieControlStyleNone; 
    movPlayer.fullscreen = NO; 
    movPlayer.shouldAutoplay=NO; 
    [movPlayer setScalingMode:MPMovieScalingModeAspectFill]; 
    [self.view addSubview:movPlayer.view]; 


    UIButton *pauseButton=[[UIButton alloc]init]; 
    [pauseButton setFrame:CGRectMake(100,220, 50, 50)]; 
    [pauseButton setBackgroundColor:[UIColor yellowColor]]; 
    [pauseButton setTag:123456789]; 
    [pauseButton setAccessibilityValue:@"445"]; 
    [pauseButton setAccessibilityLabel:@"445"]; 
    [pauseButton addTarget:self action:@selector(pauseBtnClicked:) forControlEvents:UIControlEventTouchUpInside]; 
    [self.view addSubview:pauseButton]; 


} 

-(void)pauseBtnClicked:(UIButton*)btn 
{ 
    NSLog(@"clicked on pause button"); 

    UIButton *pause = (UIButton*)[self.view viewWithTag:123456789]; 

    NSLog(@"clicked on pause button"); 

    if ([pause.accessibilityValue intValue] == 455) 
    { 
     NSLog(@"Stop"); 
     [movPlayer stop]; 
     [pause setBackgroundColor:[UIColor yellowColor]]; 
     [pause setAccessibilityValue:@"445"]; 

    } 
    else if ([pause.accessibilityValue intValue] == 445) 
    { 
     NSLog(@"Play"); 

     [movPlayer play]; 

     [pause setBackgroundColor:[UIColor brownColor]]; 
     [[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(moviePlaybackComplete:) 
               name:MPMoviePlayerPlaybackDidFinishNotification 
               object:movPlayer]; 
     [pause setAccessibilityValue:@"455"]; 

    } 
} 


- (void)moviePlaybackComplete:(NSNotification *)notification 
{ 

    NSLog(@"video playing is completed"); 
    MPMoviePlayerController *moviePlayerController = (MPMoviePlayerController*)[notification object]; 

    [[NSNotificationCenter defaultCenter] removeObserver:self 
               name:MPMoviePlayerPlaybackDidFinishNotification 
               object:moviePlayerController]; 

    [moviePlayerController stop]; 

    int pauseViewTag = 123456789; 
    UIButton *pause = (UIButton*)[self.view viewWithTag:pauseViewTag]; 

    [pause setBackgroundColor:[UIColor yellowColor]]; 



}
