swift – 呈现AVPlayerViewController StatusBar使UI跳转

func playVideoPressed(sender: UIButton){
  let videoURL = NSURL(string: "someUrl")
  let player = AVPlayer(URL: videoURL!)
  let playerViewController = AVPlayerViewController()
  playerViewController.player = player
  self.presentViewController(playerViewController, animated: true) {
    playerViewController.player!.play()
  }
}

此AVPlayerViewController的状态栏使当前视图控制器的UI跳转.我可以在此“presentViewController”调用中隐藏状态栏吗？

我试过包括

playerViewController.prefersStatusBarHidden()

但玩家继续显示状态栏.

谢谢

override func prefersStatusBarHidden() -> Bool {
    return true
}

看起来像更多的代码,考虑到我只是在观看视频,但它运作顺畅.
