Question

我有一个视频使用avPlayerLayer在图像视图中播放。调用videoViewTapped时，它也会暂停/播放。唯一的事情是，当我希望它全屏显示时，它将不会在用户打开该点时在AVPlayer中恢复该视频。我有timeStopped = player.currentTime（）来注册用户选择全屏选项的时间。我查看了Apple文档并尝试使用Seek方法，但是它们都缩短了播放结束时间。

也许我错过了一些东西。我的代码如下。目前，当我按下VC上的全屏按钮时，视频会在几秒钟后冻结。

import UIKit
import AVKit
import AVFoundation

class ViewController: UIViewController  {

    @IBOutlet weak var videoView: UIImageView!
    @IBOutlet var imageView: UIImageView!
    let videoPlayer = AVPlayerViewController()
    var player : AVPlayer!
    var avPlayerLayer : AVPlayerLayer!
    var timeStopped = CMTime()

    override func viewDidLoad() {
        super.viewDidLoad()
            guard let path = Bundle.main.path(forResource: "SampleVideo", ofType:"mp4") else {
                debugPrint("Logo-Animation4.mp4 not found")
                return
            }
            player = AVPlayer(url: URL(fileURLWithPath: path))
            avPlayerLayer = AVPlayerLayer(player: player)
            avPlayerLayer.videoGravity = AVLayerVideoGravity.resize

            videoView.layer.addSublayer(avPlayerLayer)
        }    

    //MARK: VIDEO STUFF
    override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        avPlayerLayer.frame = videoView.layer.bounds
    }


    @IBAction func videoViewTapped(_ sender: UITapGestureRecognizer) {
        if videoView.tag == 0 {
            player.play()
            videoView.tag = 1
        } else {
            player.pause()
            timeStopped = player.currentTime()
            videoView.tag = 0
        }
    }

    @IBAction func fullScreen(_ sender: Any) {
        videoPlayer.player = player

        present(videoPlayer, animated: true) {
            self.videoPlayer.showsPlaybackControls = true
        }
    }
}

您还可以使用videoPlayer中的AVPlayer，这样，当用户进入全屏模式时，您不必重新分配播放器。

let videoPlayer = AVPlayerViewController()


 override func viewDidLoad() {
    super.viewDidLoad()

        videoPlayer.player = AVPlayer(url: URL(fileURLWithPath: path))

    }


  @IBAction func videoViewTapped(_ sender: UITapGestureRecognizer) {
    if videoView.tag == 0 {
        videoPlayer.player.play()
        videoView.tag = 1
    } else {
        videoPlayer.player.pause()

        videoView.tag = 0
    }
}

@IBAction func fullScreen(_ sender: Any) {


    present(videoPlayer, animated: true) {
        self.videoPlayer.showsPlaybackControls = true
        videoPlayer.player.play()
    }
}
