Show Interstitial In Other Scenes - Admob, SpriteKit, Swift

How do I show an interstitial ad from admob every x times the user has died or every x times the user does something like presses a button? This is how I showed an interstitial ad on my GameScene and limited ad impressions with a simple if statement.


This will only work if you have the GoogleMobileAds.sdk and have imported the googlemobileads module into your GameViewController, and GameScene, OR GameOverScene.

I'll be showing you cross-scene ad implementation and programmatically limiting ad impressions.

First, in your GameViewController:

import GoogleMobileAds

class GameViewController: UIViewController, GKLocalPlayerListener, GADInterstitialDelegate {

var myAd = GADInterstitial()

override func viewDidLoad() {

    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(GameViewController.loadAndShow), name: "loadAndShow", object: nil)


Create two functions at the bottom of your GameViewController:

func loadAndShow() {

    myAd = GADInterstitial()
    let request = GADRequest()
    myAd.delegate = self


func interstitialDidReceiveAd(ad: GADInterstitial!) {

    if (self.myAd.isReady) {




You are done with GameViewController. Now head to GameOverScene or GameScene, whatever you need.

Create a global int variable:

var playCount = Int()

In your DidMoveToView say:

playCount = 1

This part is sort of confusing, kinda, not really. Go to your touchesBegan and find where you add actions to a button if it's pressed. For example, a resetGame button resets the scene. Add this there and increment the playButton Int like so:

  override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {

    for touch in touches{

        let location = touch.locationInNode(self)
        if resetGame.containsPoint(location) {

            playCount += 1


Last step. Add these two functions to the bottom of the scene you want to show interstitial ads in:

func displayAd() {

 NSNotificationCenter.defaultCenter().postNotificationName("loadAndShow", object: nil)


func checkAd() {

    if playCount % 4 == 0 {





Now every fourth time that the user presses the reset game button or dies, an interstitial ad should show up. I hope this helps.

EDIT: I forgot to tell you to call the checkAd() function. Call this function wherever your players dies. So if you have a Bool variable called died or gameover call it in the same spot. For example..

if died == true {
