Very confused about an issue I've just stumbled across. I have a swift game, mainly using SpriteKit. At the end of a game an ad is loaded. Or when the user decides to end the game an ad is also loaded.
If the game is played normally. The flow is as follows...
MenuScene -> GameScene -> [ad loads] -> GameOverScene
If the user quits the game...
MenuScene -> GameScene -> user selects pause -> user clicks quit -> [ad loads] -> Menu Scene
Both scenarios work perfectly for iOS 13
However, in iOS 12, only the user quitting mid game works, in the other scenario the app freezes (no obvious errors to me in the log)
Ending a game, via either method, calls the exact same function. Which uses a notification to load the ad.
The following code is all in the GameViewController. And the notification is posted in the GameScene.
NotificationCenter.default.addObserver(self, selector: #selector(GameViewController.showAd), name: NSNotification.Name(rawValue: "loadAndShow"), object: nil)
An ad is prepared in ViewDidLoad()
myAd = createAd()
And the function is called by the Notification
@objc func showAd() {
if (myAd.isReady) {
myAd.present(fromRootViewController: self)
myAd = createAd()
}
}
func createAd() -> GADInterstitial {
myAd = GADInterstitial(adUnitID: "MY ADMOB ID")
let request = GADRequest()
GADMobileAds.sharedInstance().requestConfiguration.testDeviceIdentifiers = ["MY DEVICE ID"]
myAd.delegate = self
myAd.load(request)
return myAd
}
Any help would be amazing
UPDATE
Have found a potential workaround. Am now presenting the ad in a different thread and no longer experiencing any freezing.
DispatchQueue.main.async {
self.myAd.present(fromRootViewController: self)
}
Can only assume iOS13 has better handling for this. And the reason the "game quit" scenario worked was because it was transitioning to the menu scene which is also the GameViewController. The app didn't like presenting an ad from the GameViewController while also transitioning to a new scene.
