问题显示视频上的子视图| Swift 5

Question

我正在设计的登录屏幕接近完成，但未能正确显示用户名和密码文本字段一旦视图控制器加载

当视图加载时执行以下函数-它正确地播放视频并正确显示图像和loginButton，它似乎也似乎显示文本字段，直到视频完全加载和播放。

func playVideo() {
guard let path = Bundle.main.path(forResource: "videoFile", ofType: "mp4") else {
return
}

let asset: AVAsset = AVAsset(url: URL(fileURLWithPath: path))
let playerItem = AVPlayerItem(asset: asset)
let queuePlayer = AVQueuePlayer(playerItem: playerItem)

self.playerLooper = AVPlayerLooper(player: queuePlayer, templateItem: playerItem)
let playerLayer = AVPlayerLayer(player: queuePlayer)
playerLayer.frame = self.view.bounds
playerLayer.videoGravity = .resizeAspectFill
self.videoLayer.layer.addSublayer(playerLayer)
queuePlayer.play()

videoLayer.bringSubviewToFront(img)
videoLayer.bringSubviewToFront(usernameTF)
videoLayer.bringSubviewToFront(passwordTF)
videoLayer.bringSubviewToFront(signinButton)

}

你知道是什么原因导致的吗?

Answer 1

您可以根据需要更改此代码。

var player : AVPlayer?
var playerViewController : AVPlayerViewController?   
func playLiveUrl(url:String){
let videoURL = URL(string: "http://bla blah.com")
self.player = AVPlayer(url: videoURL!)
self.playerViewController = AVPlayerViewController()
playerViewController?.player = self.player
playerViewController?.view.frame = self.topPlayerView.frame 
playerViewController?.player?.play()
self.topPlayerView.addSubview(playerViewController?.view ?? UIView()) // Container topPlayerView which contains a player

}
var topPlayerView : UIView = {
let view = UIView()
view.translatesAutoresizingMaskIntoConstraints = false
view.backgroundColor = .black
return view
}()
