ios - 在 View 中使用 AVPlayer 播放多个视频

Question

我有一个 UIView，其中包含一些文本和 View 。在每个 View 中，我都需要使用 AVPlayer 播放视频，但我的问题是只有第一个 View 显示视频:

这是我的代码:

func playVideo(name:String , onView:UIView) {

    let path = Bundle.main.path(forResource: name, ofType: "mp4")
    let videoURL = URL(fileURLWithPath: path!)
    let player = AVPlayer(url: videoURL)
    let playerLayer = AVPlayerLayer(player: player)
    playerLayer.frame = onView.frame
    playerLayer.videoGravity = AVLayerVideoGravity.resizeAspectFill
    onView.layer.addSublayer(playerLayer)
    player.play()

}

使用函数:

override func viewDidLoad() {
        super.viewDidLoad()

//ScrollView
    scrollView.contentSize = menuView.frame.size
    scrollView.addSubview(menuView)

//Play videos 
 playVideo(name: "pizza", onView: videoView1)
 playVideo(name: "salad", onView: videoView2)
 playVideo(name: "fries", onView: videoView3)
}

当我运行应用程序时，视频仅在 videoView1 中播放，请问为什么会发生这种情况？ 我还将我的代码放在 viewWillAppear , viewDidLayoutSubviews

根据 Apple 文档:

AVPlayer 类

Note

AVPlayer is intended for playing a single media asset at a time.
