iOS

Question

我关注是为了让视图填充背景。所以我使用了一个名为 myview 的蓝色背景视图，但是当我添加视频层时，我的结果很糟糕。

class MovViewController: UIViewController {

    var avPlayer: AVPlayer!
    @IBOutlet weak var myview: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()
        let filepath: String? = Bundle.main.path(forResource: "video_fondo", ofType: "mp4")
        let fileURL = URL.init(fileURLWithPath: filepath!)

        let player = AVPlayer(url: fileURL)
        let playerLayer = AVPlayerLayer(player: player)

        playerLayer.frame = myview.bounds
        myview.layer.insertSublayer(playerLayer, at: 0)
        player.play()

    }
}

结果：

Answer 1

播放器图层背景默认透明。如果你想隐藏后面的蓝色视图，请尝试在播放器层上设置背景颜色。

playerLayer.backgroundColor = UIColor.black.cgColor

Answer 2

最后我使用：

playerLayer.videoGravity = AVLayerVideoGravity.resize
