【问题描述】：

videoPlayer = (AVPlayer.init(url: url as URL) as AVPlayer?)!

videoPlayer.actionAtItemEnd = .none

var videoLayer = AVPlayerLayer(player: videoPlayer)

videoLayer.frame = CGRect(x: 0, y: 0, width: (pickVideo?.frame.width)!, height: (pickVideo?.frame.height)!)

pickVideo?.layer.addSublayer(videoLayer)

videoLayer.addSublayer((closeImage?.layer)!)

let tapGueturePlayVideo = UITapGestureRecognizer(target: self, action: #selector(playVideo(sender:)))
tapGueturePlayVideo.delegate = self
tapGueturePlayVideo.numberOfTapsRequired = 1
pickVideo?.addGestureRecognizer(tapGueturePlayVideo)
pickVideo?.isUserInteractionEnabled = true

我在这里为 Tapgesture 创建了函数：

func playVideo(sender: UITapGestureRecognizer) 

    self.videoPlayer.play()

如果长按并点按视频播放流畅..如果我点按屏幕侧面并尝试再次播放它不播放.. 点按时断点调用但玩家不玩

【参考方案1】：

您必须使用 prepareToPlay 将 AVPlayer 设置回流的开头并将 currentPlaybackTime 设置为 0。

AVPlayer doesn't play more than one time

videoPlayer.currentPlaybackTime = 0
videoPlayer.prepareToPlay()

【参考方案2】：

最好的方法是使用AVPlayerViewController 和contentOverlayView

像这样：

 override func viewDidLoad() 
    super.viewDidLoad()

    let videoURL = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")!
    videoPlayer = AVPlayer(url: videoURL)
    let avPlayerController = AVPlayerViewController()
    avPlayerController.player = videoPlayer
    avPlayerController.view.frame = CGRect(x: 100, y: 50, width:200, height: 300)
    avPlayerController.showsPlaybackControls = false
    self.view.addSubview(avPlayerController.view)

    let tapGesture:UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(ViewController.playVideo(sender:)))
    tapGesture.numberOfTapsRequired = 1
    avPlayerController.contentOverlayView?.addGestureRecognizer(tapGesture)



 @objc func playVideo(sender: UITapGestureRecognizer) 

        self.videoPlayer?.play()

    

【讨论】：

使用未解决的标识符“AVPlayerViewController”面临此问题

只需添加import AVKit

我在一个示例项目中尝试了代码，单击播放视频...但是当我再次点击时，视频无法播放！如何解决此问题
