Question

构建我的第一个应用并尝试将背景视频水平放置。

下面是代码l＆＃39; m

override func viewDidLoad()
{
    super.viewDidLoad()

    let URL = Bundle.main.url(forResource: "homedocapp", withExtension: "mp4")

    Player = AVPlayer.init(url: URL!)

    PlayerLayer = AVPlayerLayer(player: Player)
    PlayerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
    PlayerLayer.frame = self.view.frame; PlayerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
    PlayerLayer.zPosition = -1

    Player.actionAtItemEnd = AVPlayerActionAtItemEnd.none

    self.view.layer.addSublayer(PlayerLayer)

    Player.play()

    view.layer.insertSublayer(PlayerLayer, at: 0)

    NotificationCenter.default.addObserver(self, selector: #selector(playerItemReachEnd(notification:)), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: Player.currentItem)


}

AVPlayer Horizontal display

谢谢你的进步

Answer 1

调用'viewDidLoad'时，视图的大小仍然不正确。所以你的PlayerLayer也会有不正确的大小。尝试将代码移动到'viewDidLayoutSubviews'函数：

override func viewDidLayoutSubviews() 
{
    super.viewDidLayoutSubviews()

    // Set up your player layer instance here
}

Answer 2

在viewDidLoad中初始化时，您必须使用约束调整播放器的大小，导致self.view.frame不正确。

Answer 3

Spilt screen

旋转时，我正在分屏。

class ViewController: UIViewController  {

var Player: AVPlayer!
var PlayerLayer: AVPlayerLayer!



override func viewDidLayoutSubviews()
{
    super.viewDidLayoutSubviews()

    let URL = Bundle.main.url(forResource: "homedocapp", withExtension: "mp4")

    Player = AVPlayer.init(url: URL!)

    PlayerLayer = AVPlayerLayer(player: Player)
    PlayerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
    PlayerLayer.frame = view.layer.frame

    Player.actionAtItemEnd = AVPlayerActionAtItemEnd.none


    Player.play()

    view.layer.insertSublayer(PlayerLayer, at: 0)

    NotificationCenter.default.addObserver(self, selector: #selector(playerItemReachEnd(notification:)), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: Player.currentItem)


}
