在 AVPlayerViewController 上显示一个 UILabel
Display a UILabel over AVPlayerViewController
我有一个 AVPlayerViewController 并想在播放器上显示一个 UILabel,但我无法让 UILabel 出现。这曾经在我使用 MPMoviePlayerViewController 时工作正常,但自从切换到 AVPlayerViewController 后,它不再工作了。
我是这样启动 AVPlayer 的:
AVPlayer *player = [AVPlayer playerWithURL:theURL];
AVPlayerViewController *theMovie = [[AVPlayerViewController alloc] init];
[self presentViewController:theMovie animated:YES completion:nil];
theMovie.player = player;
[player play];
UILabel 定义为 lblOverlayView,设置如下:
lblOverlayView = [[UILabel alloc] init];
lblOverlayView.frame = CGRectMake(0, 100, self.view.frame.size.width, 60);
lblOverlayView.backgroundColor = [UIColor blackColor];
lblOverlayView.alpha = 0.5f;
NSString *combinedString1 = [@"Now Playing" stringByAppendingString:@" "];
NSString *combinedString2= [combinedString1 stringByAppendingString:@"Podcasts"];
lblOverlayView.text =combinedString2;
lblOverlayView.textColor = [UIColor whiteColor];
lblOverlayView.textAlignment = NSTextAlignmentCenter;
lblOverlayView.numberOfLines = 0;
lblOverlayView.font =[UIFont boldSystemFontOfSize:14];
lblOverlayView.autoresizingMask = (UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin);
[theMovie.view addSubview:lblOverlayView];
[theMovie.view bringSubviewToFront:lblOverlayView];
如何让 UILabel 出现?
使用控制器的.contentOverlayView
:
//[theMovie.view addSubview:lblOverlayView];
//[theMovie.view bringSubviewToFront:lblOverlayView];
[theMovie.contentOverlayView addSubview:lblOverlayView];
