在我的应用程序中，我使用了 public static String extract(String myStr) {
Pattern p = compile("Name:(?m)^.*$");
Matcher m = p.matcher(myStr);
while (m.find()) {
String theGroup = m.group(0);
System.out.format("'%s'\n", theGroup);
return m.group(0);
}
return null;
}
来播放视频，如果我们播放视频并向前一页播放视频，则可以在后面播放视频，但如果我们再播放相同的视频，我们必须继续显示视频，它不应该从开始，这里我可以根据视频持续时间设置滑块位置，但不显示视频内容声音的屏幕即将到来。
第一次播放任何视频我称之为方法
AVPlayer如果用户第二次播放相同的视频，我会检查存储在userdefaults中的当前网址，如果它正在播放相同的视频，我确实喜欢关注
func setup() {
UserDefaults.standard.set(videoString as NSString, forKey: CurrentURL)
UserDefaults.standard.synchronize()
let targetTime:CMTime = CMTimeMake(0, 1)
mediaPlayer.seek(to: targetTime)
mediaPlayer.pause()
print("Video URL \(videoString)")
let url = NSURL(string: videoString)
let playerItem = AVPlayerItem(url: url! as URL)
mediaPlayer=AVPlayer(playerItem: playerItem)
let playerLayer=AVPlayerLayer(player: mediaPlayer)
playerLayer.frame = self.view.bounds
playerLayer.backgroundColor = UIColor.black.cgColor
//playerLayer.videoGravity = AVLayerVideoGravityResize
playerLayer.videoGravity = AVLayerVideoGravityResizeAspect
self.view.layer.addSublayer(playerLayer)
AppDelegate.shared().showLoading()
videoView.isHidden = false
mediaPlayer.play()
let duration : CMTime = mediaPlayer.currentItem!.asset.duration
let seconds : Float64 = CMTimeGetSeconds(duration)
videoSlider.maximumValue = Float(seconds)
videoPlayButton.setImage(UIImage(named: "Pause"), for: .normal)
videoPlaying = true
//Adding Default Periodic Observer On Player
mediaPlayer.addPeriodicTimeObserver(forInterval: CMTimeMakeWithSeconds(1, 1), queue: DispatchQueue.main) { (CMTime) -> Void in
if mediaPlayer.currentItem?.status == .readyToPlay {
AppDelegate.shared().removeLoading()
self.videoSlider.value = Float(CMTimeGetSeconds(mediaPlayer.currentTime()))
let currentTime : Int = Int(CMTimeGetSeconds(mediaPlayer.currentTime()))
let minutes = currentTime/60
let seconds = currentTime - minutes * 60
self.durationLabel.text = NSString(format: "%02d:%02d", minutes,seconds) as String
}
}
}
但是，如果我再次播放相同的视频，则lauer不会显示视频内容，如果用户播放已经运行的视频，则应该从当前持续时间继续而不是重新开始
