I am trying to add admob to my app but I get an error.
Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value
I have followed along on developer.google.com and on stackoverflow.com but I can't seem to fix it.
Here is my code:
import UIKit import GoogleMobileAds
class ViewController: UIViewController, GADBannerViewDelegate {
//Place your instance variables here
let allQuestions = QuestionBank()
var pickedAnswer : Bool = false
var questionNumber : Int = 0
var score : Int = 0
var bannerView: GADBannerView!
var banner: GADBannerView!
@IBOutlet weak var questionLabel: UILabel!
@IBOutlet weak var scoreLabel: UILabel!
@IBOutlet weak var GoogleBannerView: GADBannerView!
@IBOutlet weak var progressLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
banner = GADBannerView(frame: self.view.frame)
GADMobileAds.configure(withApplicationID: "ca-app-pub-3940256099942544/2934735716")
bannerView.adUnitID = "ca-app-pub-3940256099942544/2934735716" ***//Crashes Here***
bannerView.rootViewController = self
bannerView.load(GADRequest())
bannerView.delegate = self
/// Tells the delegate an ad request loaded an ad.
func adViewDidReceiveAd(_ bannerView: GADBannerView) {
print("adViewDidReceiveAd")
}
/// Tells the delegate an ad request failed.
func adView(_ bannerView: GADBannerView,
didFailToReceiveAdWithError error: GADRequestError) {
print("adView:didFailToReceiveAdWithError: \(error.localizedDescription)")
}
/// Tells the delegate that a full-screen view will be presented in response
/// to the user clicking on an ad.
func adViewWillPresentScreen(_ bannerView: GADBannerView) {
print("adViewWillPresentScreen")
}
/// Tells the delegate that the full-screen view will be dismissed.
func adViewWillDismissScreen(_ bannerView: GADBannerView) {
print("adViewWillDismissScreen")
}
/// Tells the delegate that the full-screen view has been dismissed.
func adViewDidDismissScreen(_ bannerView: GADBannerView) {
print("adViewDidDismissScreen")
}
/// Tells the delegate that a user click will open another app (such as
/// the App Store), backgrounding the current app.
func adViewWillLeaveApplication(_ bannerView: GADBannerView) {
print("adViewWillLeaveApplication")
}
bannerView = GADBannerView(adSize: kGADAdSizeBanner)
addBannerViewToView(bannerView)
nextQuestion()
}
func addBannerViewToView(_ bannerView: GADBannerView) {
bannerView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(bannerView)
view.addConstraints(
[NSLayoutConstraint(item: bannerView,
attribute: .bottom,
relatedBy: .equal,
toItem: bottomLayoutGuide,
attribute: .top,
multiplier: 1,
constant: 0),
NSLayoutConstraint(item: bannerView,
attribute: .centerX,
relatedBy: .equal,
toItem: view,
attribute: .centerX,
multiplier: 1,
constant: 0)
])
}
Thanks for anyone who can help!!
