ios - AVPlayer-UILabel在视频中不可见

    NSString *urlPath;
    NSURL *videoUrl;

    urlPath = [[NSBundle mainBundle] pathForResource:@"fogLoop" ofType:@"mp4"];
    videoUrl = [NSURL fileURLWithPath:urlPath];

    avPlayer = [AVPlayer playerWithURL:videoUrl];
    avPlayerLayer = [AVPlayerLayer playerLayerWithPlayer:avPlayer];

    avPlayerLayer.frame = videoView.layer.bounds;

    avPlayerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill;

    [videoView.layer addSublayer: avPlayerLayer];

    avPlayer.actionAtItemEnd = AVPlayerActionAtItemEndNone;

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(playerItemDidReachEnd:)
                                                 name:AVPlayerItemDidPlayToEndTimeNotification
                                               object:[avPlayer currentItem]];

    [avPlayer play];

我在此 View 上有几个UILabel。我只希望视频确实是背景元素。使用此代码，它似乎可以播放所有UI元素。我如何使其进入后台？

最佳答案

您可以使用 View 图层的zPosition属性(它是CALayer对象)来更改 View 的z索引。

 theView.layer.zPosition = 1;

并将标签带到前面
