我试图AVPlayer通过UISlider搜索来实现流畅的视频清理,似乎Apple有技术问答并解释了如何实现这一点,但我的问题是如何使用此方法并使用UISlider更改播放器当前时间: stopPlayingAndSeekSmoothlyToTime(newChaseTime:CMTime)

这是我的代码:

//Play Intro Movie
let videoURL = Bundle.main.url(forResource: "intro", withExtension: "mp4")
player = AVPlayer(url:videoURL!)
let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = self.view.frame
view.layer.addSublayer(playerLayer)
//videoPlayer.play()


view.addSubview(slider)
slider.maximumValue = 0
slider.maximumValue = Float(CMTimeGetSeconds((player.currentItem?.asset.duration)!))

这是Apple示例代码:

func stopPlayingAndSeekSmoothlyToTime(newChaseTime:CMTime)
    {
        player.pause()

        if CMTimeCompare(newChaseTime, chaseTime) != 0
        {
            chaseTime = newChaseTime;

            if !isSeekInProgress
            {
                trySeekToChaseTime()
            }
        }
    }




    func trySeekToChaseTime()
    {
        if playerCurrentItemStatus == .unknown
        {
            // wait until item becomes ready (KVO player.currentItem.status)
        }
        else if playerCurrentItemStatus …
