ios - 调整播放器窗口的大小

Question

我有一个 UIview，我在其中嵌入了一个 AVPlayer。现在当我玩它时，它似乎没有覆盖整个 UIview。下面是代码:

@IBOutlet weak var introVideo: UIView!

var player: AVPlayer!

func playIntro() {

    if let moviePath = Bundle.main.path(forResource: "intro", ofType: "mp4") {
        let movieURL = URL(fileURLWithPath: moviePath)
        player = AVPlayer(url: movieURL)
        let playerLayer = AVPlayerLayer()
        playerLayer.player = player
        playerLayer.frame = introVideo.bounds
        playerLayer.backgroundColor = UIColor.clear.cgColor
        player.actionAtItemEnd = .none
        playerLayer.videoGravity = AVLayerVideoGravityResizeAspect
        introVideo.layer.addSublayer(playerLayer)
        player.play()
        NotificationCenter.default.addObserver(self,
                                               selector: #selector(playerItemDidReachEnd(notification:)),
                                               name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,
                                               object: player.currentItem)        }
}

它看起来像这样:

如何解决这个问题

Answer 1

我解决了。我在 viewDidLoad() 中调用这个函数，但它在每次加载时都会以某种方式更新 View 。因此，出于这个原因，应该在 viewDidLayoutSubviews()

中更新边界

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    playIntro()
}
