SpriteKit and GoogleAdMobs interstitial - ios

Question

I am trying to load this google interstitial ad when the game is over.
if (self.interstitial.isReady)
{
self.interstitial.presentFromRootViewController(self)
}
But I am getting an error that says "Cannot convert value of type 'GameScene' to expected argument type 'UIViewController!".
I have used the same lines of code with my other apps that don't use sprite kit, is it different with sprite kit?

Yes it's different in SpriteKit because you trying to present from a SKScene and not a UIViewController.
Try this and see if it works
if (self.interstitial.isReady) {
self.interstitial.presentFromRootViewController(self.view?.window?.rootViewController)
}
If you are getting a nil crash now than you did not init the ad property correctly. You should also have some checks to ensure this does not happen.
This is how the adMob code from my gitHub helper looks.
You should have a property like so
var interstitial: GADInterstitial?
Than in view didLoad you should preload the ad
interstitial = adMobLoadInterAd()
This is pre-loading code.
func adMobLoadInterAd() -> GADInterstitial {
Debug.print("AdMob inter loading...")
let googleInterAd = GADInterstitial(adUnitID: "Your adMob ID")
googleInterAd.delegate = self
let request = GADRequest()
request.testDevices = [kGADSimulatorID] // DEBUG only
googleInterAd.loadRequest(request)
return googleInterAd
}
Than when you want to show an ad you call this
func adMobShowInterAd() {
guard interstitial != nil && interstitial!.isReady else { // calls interDidReceiveAd
Debug.print("AdMob inter is not ready, reloading")
interstitial = adMobLoadInterAd()
return
}
Debug.print("AdMob inter showing...")
interstitial?.presentFromRootViewController(self.view?.window?.rootViewController)
}
Than finally in the delegate methods you should pre load a new ad when the current ad is dismissed.
func interstitialDidDismissScreen(ad: GADInterstitial!) {
Debug.print("AdMob inter closed")
interstitial = adMobLoadInterAd()
}
