Swift-Can't present Game Center with SpriteKit

Question

This the code block I'm having trouble with.It gives me error because of 'presentViewController'

func authenticateLocalPlayer(){

    let localPlayer = GKLocalPlayer.localPlayer()

    localPlayer.authenticateHandler = {(viewController, error) -> Void in

        if (viewController != nil) {
           self.presentViewController(viewController!, animated: true, completion: nil)

        }

        else {
            print((GKLocalPlayer.localPlayer().authenticated))
        }
    }

}

I know it's because SKScene has already has a UIViewController, but I don't know how else to represent it.

Answer 1

You can't call presentViewController from within your SKScene, you need to call it on a UIViewController.

Therefore you want to find the parent view controller that contains your Sprite Kit content and call the function there.
