从某个点开始视频 Swift

Question

我有一个使用 avPlayerLayer 在图像视图中播放的视频。

它 pauses/plays 当调用 videoViewTapped 时（i.t。用户点击 imageView）。还有一个进入全屏模式的选项。

我尝试使用 timeStopped = player.currentTime() 来记录用户选择全屏选项的时间，然后在全屏时使用此点开始播放视频。

目前，当我进入全屏模式时，视频会从头开始重新播放并在几秒钟后冻结，而不是在调用全屏模式时视频所在的位置。下面是我的代码：

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
        }
    }
}

有人能指出我的错误吗？

您还可以使用 videoPlayer 中的 AVPlayer，这样当用户进入全屏模式时就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()
    }
}
