How to perform some action on Play and Pause actions of AVPlayer?

I have used AVPlayer to play video on my swift application. I want to place a Play button (custom button) at the middle of video. I know how to play and pause video on tapping the button.

I couldn't find how to show/hide the custom button when the video is played/paused from default buttons? Are there any listener or something which triggers when the video is played/paused?

I also want to hide the "Audio & Subtitles" icon from default control.

player init then,

self.player?.addObserver(self, forKeyPath: "rate", options: .new, context: nil)

override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {
    if self.player?.rate == 0 {
        print("Pause")
    }else {
        print("Play")
    }
}

Here is how you can listen to player state changes and hide/show buttons: (assume your player is named player, and button is playButton)

player.addObserver(self, forKeyPath: "rate", options: .New, context: nil) // somewhere after player init
...
override func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject?, change: [String : AnyObject]?, context: UnsafeMutablePointer<Void>) {
  if keyPath == "rate" {
    playButton.enabled = player.rate == 1 
  } else {
    super.observeValueForKeyPath(keyPath, ofObject: object, change: change, context: context)
  }
}

If rate of player is equal to 0 it means that video is not playing.
