load interstitial ad on IBAction button - ios

Question

When my callButton is clicked it rings a phone number, I want to display my interstitial ad before the call is made. I have tested my ad on the "IBAction function ad" button and it works on the button but when I call it on the callButton func it will not work and goes straight to making a call.
class ProfilePageViewController: UIViewController, MFMessageComposeViewControllerDelegate, UITableViewDelegate, UIAlertViewDelegate, GADInterstitialDelegate {
#IBAction func ad(_ sender: Any) {
if self.interstitialAd.isReady {
self.interstitialAd.present(fromRootViewController: self)
}
}
#IBAction func callButton(_ sender: Any) {
if let contactopt = contact{
if let url = NSURL(string: "tel://\(contactopt)") {
// UIApplication.shared.openURL(url as URL)
UIApplication.shared.open(url as URL, options: [:], completionHandler: nil)
}
}
}
var interstitialAd: GADInterstitial!
func reloadInterstitialAd() -> GADInterstitial {
var interstitial = GADInterstitial(adUnitID: "ca-app-pub-/6966780536")
interstitial.delegate = self
interstitial.load(GADRequest())
return interstitial
}
func interstitialDidDismissScreen(ad: GADInterstitial!) {
self.interstitialAd = reloadInterstitialAd()
}
func interstitialDidDismissScreen(_ ad: GADInterstitial) {
interstitialAd = reloadInterstitialAd()
}
override func viewDidLoad() {
self.interstitialAd = GADInterstitial(adUnitID: "ca-app-pub-/6966780536")
let request = GADRequest()
request.testDevices = ["2077ef9a63d2b398840261c8221a0c9b"]
self.interstitialAd.load(request)
self.interstitialAd = reloadInterstitialAd()
super.viewDidLoad()
}
}

Answer 1

Of course it goes to making a call. That's what you're telling it to do with UIApplication.shared.open.
Make the call once the ad has been dismissed in interstitialDidDismissScreen.
Also check to see if there is an ad to present, interstitialAd.isReady. If there is no ad to present go straight to making the call.
You're also doing the same thing twice in your viewDidLoad:
// Sets up an ad
self.interstitialAd = GADInterstitial(adUnitID: "ca-app-pub-/6966780536")
let request = GADRequest()
request.testDevices = ["2077ef9a63d2b398840261c8221a0c9b"]
self.interstitialAd.load(request)
// Creates a new ad
self.interstitialAd = reloadInterstitialAd()
Just call self.interstitialAd = reloadInterstitialAd().

Answer 2

I believe your problem has to do with the synchrony of the present method on the interstitial. I do not know what the implementation is, but it seems like the ad's presentation does not block the thread on which it was called. You should try implementing GADInterstitialDelegate to grab the event when the ad is presented then proceed to make your call from there.

Try this:
GADInterstitial is a one time use object. That means once an
interstitial is shown, hasBeenUsed returns true and the interstitial
can't be used to load another ad. To request another interstitial,
you'll need to create a new GADInterstitial object. The best practice,
as shown above, is to have a helper method to handle creating and
loading an interstitial.
func createAndLoadInterstitial() -> GADInterstitial {
var interstitial = GADInterstitial(adUnitID: "ca-app-pub-3940256099942544/4411468910")
interstitial.delegate = self
interstitial.load(GADRequest())
return interstitial
}
func interstitialDidDismissScreen(_ ad: GADInterstitial) {
interstitial = createAndLoadInterstitial()
}
#IBAction func ad(_ sender: Any) {
if self.interstitialAd.isReady {
self.interstitialAd.present(fromRootViewController: self)
}
}
