AVPlayer, how to save the current recording time - ios

Question

When I press pause and then play, the music playing again how to solve this problem?
I know that I need to use seekTime(: CMTime), but I don't get

It's all code
class ViewControllerAudioDetail: UIViewController {
#IBOutlet var list: TableViewControllerAudioList!
#IBOutlet weak var playChange: UIButton!
#IBOutlet weak var timeAudio: UILabel!
#IBOutlet weak var playbackSlider: UISlider!
var player = AVPlayer()
override func viewDidLoad() {
super.viewDidLoad()
navigationItem.title = "БИБЛИОТЕКА"
}
#IBAction func play(_ sender: Any) {
if player.rate == 0 {
let url = URL(string: ViewControllerAudioDetail.urlAudio[0])
let playerItem = AVPlayerItem(url: url!)
player = AVPlayer(playerItem:playerItem)
player.rate = 1.0;
player.play()
playChange.setImage(UIImage(named:"Pause.png"), for: UIControlState.normal)
let duration : CMTime = playerItem.asset.duration
let seconds : Float64 = CMTimeGetSeconds(duration)
playbackSlider.tintColor = UIColor.green
let _ = player.addPeriodicTimeObserver(forInterval: CMTime(seconds: 1, preferredTimescale: CMTimeScale(NSEC_PER_SEC)), queue: DispatchQueue.main) { [weak self] (time) in
self?.playbackSlider.value = Float(CMTimeGetSeconds(time)) / Float(seconds)
}
} else {
playChange.setImage(UIImage(named:"Play.png"), for: UIControlState.normal)
player.pause()
}
}
#IBAction func audioPlaybackSlider(_ sender: Any) {
//перемотка аудиозвука
let duration : CMTime = player.currentItem!.duration
let totalDuration : Float64 = CMTimeGetSeconds(duration)
let value = self.playbackSlider.value
let durationToSeek = Float(totalDuration) * value
player.seek(to: CMTimeMakeWithSeconds(Float64(durationToSeek),player.currentItem!.duration.timescale)) { [](state) in
}
}
}

The problem in your code is, you always create a new player object inside your play method. That is why it always starts from the beginning of the audio.
This should solve your problem
class ViewControllerAudioDetail: UIViewController {
#IBOutlet var list: TableViewControllerAudioList!
#IBOutlet weak var playChange: UIButton!
#IBOutlet weak var timeAudio: UILabel!
#IBOutlet weak var playbackSlider: UISlider!
var player:AVPlayer?
override func viewDidLoad() {
super.viewDidLoad()
navigationItem.title = "БИБЛИОТЕКА"
setupAudioPlayer()
}
func setupAudioPlayer(){
let url = URL(string: ViewControllerAudioDetail.urlAudio[0])
let playerItem = AVPlayerItem(url: url!)
player = AVPlayer(playerItem:playerItem)
playbackSlider.tintColor = UIColor.green
let _ = player!.addPeriodicTimeObserver(forInterval: CMTime(seconds: 1, preferredTimescale: CMTimeScale(NSEC_PER_SEC)), queue: DispatchQueue.main) { [weak self] (time) in
self?.updateSlider(time: time)
}
}
func updateSlider(time:CMTime){
let duration = CMTimeGetSeconds(player!.currentItem!.asset.duration)
self.playbackSlider.value = Float(CMTimeGetSeconds(time)) / Float(duration)
}
#IBAction func play(_ sender: Any) {
if player?.rate == 0 {
player?.rate = 1.0;
player?.play()
playChange.setImage(UIImage(named:"Pause.png"), for: UIControlState.normal)
} else {
playChange.setImage(UIImage(named:"Play.png"), for: UIControlState.normal)
player?.pause()
}
}
#IBAction func audioPlaybackSlider(_ sender: Any) {
//перемотка аудиозвука
let duration = CMTimeGetSeconds(player!.currentItem!.asset.duration)
let value = self.playbackSlider.value
let durationToSeek = Float(duration) * value
self.player?.seek(to: CMTimeMakeWithSeconds(Float64(durationToSeek),player!.currentItem!.duration.timescale)) { [](state) in
}
}
}
