I have implemented

ReplayKit

in my

SpriteKit

game, but since everything is done within the

GameViewController

the record button appears too early. Please see my

GameViewController

class below:

class GameViewController: UIViewController, RPPreviewViewControllerDelegate

{

    var videoRecButton: UIButton

!

    var videoRecImage: UIImage!

    override func viewDidLoad() {

       super.viewDidLoad()

       let skView = self.view as? SKView

      if skView?.scene == nil {

        skView?.showsFPS = true

        skView?.showsNodeCount = true

        skView?.showsPhysics = true

        skView?.ignoresSiblingOrder = false

        let posterScene = PosterScene(size: skView!.bounds.size)

        posterScene.scaleMode = .aspectFill

        skView?.presentScene(posterScene)

      videoRecButton = UIButton(type: .custom)

      videoRecImage = UIImage(named:"videoRecButton.png")

      videoRecButton.frame = CGRect(x:0, y: 0, width: (videoRecImage?.size.width)!, height: (videoRecImage?.size.height)!) videoRecButton.setImage(videoRecImage, for: .normal)

      videoRecButton.addTarget(self, action:#selector(self.videoRecButtonClicked), for: .touchUpInside)

      self.view.addSubview(videoRecButton)

    func videoRecButtonClicked() {

      print("Button Clicked")

      startRecording()

    func startRecording() {

      let recorder = RPScreenRecorder.shared()

      recorder.startRecording{ [unowned self] (error) in

      if let unwrappedError = error {

        print(unwrappedError.localizedDescription)

        } else {

         self.videoRecButton.addTarget(self, action:#selector(self.stopRecording), for: .touchUpInside)

   func stopRecording() {

      let recorder = RPScreenRecorder.shared()

      recorder.stopRecording { [unowned self] (preview, error) in self.navigationItem.rightBarButtonItem =    UIBarButtonItem(title: "Start", style: .plain, target: self, action: #selector(self.startRecording))

      if let unwrappedPreview = preview {

        unwrappedPreview.previewControllerDelegate = self self.present(unwrappedPreview, animated: true)

   func previewControllerDidFinish(_ previewController: RPPreviewViewController) {

   dismiss(animated: true)

   override var shouldAutorotate: Bool {

    return true

   override var supportedInterfaceOrientations: UIInterfaceOrientationMask {

     if UIDevice.current.userInterfaceIdiom == .phone {

     return .allButUpsideDown

     } else {

       return .all

   override func didReceiveMemoryWarning() {

     super.didReceiveMemoryWarning()

   override var prefersStatusBarHidden: Bool {

      return true

How can I call the
```
startRecording
```
and
```
stopRecording
```
functions from a class that inherits from
```
SKScene
```
like
```
GameScene
```
class?
How can enable, disable and hide the
```
videoRecButton
```
button from the
```
GameScene
```
class?
