AVPlayerController - Buttons not working on full screen

Question

I'm trying to understand how AVPlayer & AVPlayerController works. I'm embedded my player in a view so my player has two mode : little & full screen. When it's little the play/plause button and full screen button work very well. But once it's full screen, the following buttons has no effect : play, pause, done, minimise.

Here is my code :

    let videoURL = NSURL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
    let avPlayer:AVPLayer = AVPlayer(url: videoURL! as URL)
    let playerController = AVPlayerViewController()
    playerController.player = avPlayer
    playerController.view.backgroundColor = UIColor.racingGreenColor();
    playerController.view.translatesAutoresizingMaskIntoConstraints = false;
    playerController.showsPlaybackControls = true;
    self.middleView.addSubview(playerController.view)
    //avPlayer.play()

    self.middleView.addConstraint(NSLayoutConstraint(item: playerController.view, attribute: .width, relatedBy: .equal, toItem: self.middleView, attribute: .width, multiplier: 1, constant: 0));
    self.middleView.addConstraint(NSLayoutConstraint(item: playerController.view, attribute: .height, relatedBy: .equal, toItem: self.middleView, attribute: .height, multiplier: 1, constant: 0));
    self.middleView.addConstraint(NSLayoutConstraint(item: playerController.view, attribute: .centerX, relatedBy: .equal, toItem: self.middleView, attribute: .centerX, multiplier: 1, constant: 0));
    self.middleView.addConstraint(NSLayoutConstraint(item: playerController.view, attribute: .centerY, relatedBy: .equal, toItem: self.middleView, attribute: .centerY, multiplier: 1, constant: 0));

Can someone help me please ? Is there a delegate for the 4 methods i'm interested in ?

Answer 1

self.addChildController(playerController);

I've add it on your main view controller and it does the trick for "Done" and "Minimise".
