How to present ads during certain scenes in sprite-kit? - swift

Question

This is my first time developing an app using swift and sprite-kit. I would like to integrate adMob into it. I have been searching a solution to my problem but I've had no success.
I have the following code set up inside GameViewController.swift
override func viewDidLoad() {
super.viewDidLoad()
bannerView = GADBannerView(adSize: kGADAdSizeSmartBannerPortrait)
bannerView.isHidden = true
bannerView.adUnitID = "ca-app-pub-************************"
bannerView.rootViewController = self
view.addSubview(bannerView)
// Configure the view.
let skView = self.view as! SKView
skView.showsFPS = false
skView.showsNodeCount = false
/* Sprite Kit applies additional optimizations to improve rendering performance */
skView.ignoresSiblingOrder = true
// Create and configure the scene.
let aspectRatio = skView.bounds.size.height / skView.bounds.size.width
let scene = MainMenuScene(size:CGSize(width: 320, height: 320 * aspectRatio))
skView.presentScene(scene)
showBanner()
}
func showBanner() {
bannerView.isHidden = false
let request = GADRequest()
request.testDevices = ["******************"]
bannerView.load(request)
}
This setup displays the ad on all of my scenes perfectly but my question is, how would I be able to make it show on MainMenuScene.swift and GameOverScene.swift by using NotificationCenter? Both of these are their own class.

Answer 1

As you mentioned you can use Notification Center.
Create a key for your notification to avoid typos. You can put this anywhere you like in your project (outside any class or a new .swift file)
extension Notification.Name {
static let showBannerAd = Notification.Name(rawValue: "ShowBanner")
}
Than in your GameViewController add the observer in ViewDidLoad
NotificationCenter.default.addObserver(self, selector: #selector(showBanner), name: .showBannerAd, object: nil) // selector is the method to call
and in your SKScene(s) you can post the notification like so when you need to show the banner.
NotificationCenter.default.postNotificationName(.showBannerAd, object: nil)
Alternatively I have a helper on Github which will make this much easier and cleaner.
