Here's how I managed to add a banner to my app:
1. Add this to your ViewDidLoad
bannerView = GADBannerView(adSize: kGADAdSizeSmartBannerPortrait)
addBannerViewToView(bannerView)
bannerView.delegate = self
bannerView.adUnitID = "ca-app-pub-3940256099942544/2934735716" //This is the test ID, always use this to test your app.
bannerView.rootViewController = self
bannerView.load(GADRequest())
2. Add these functions, you can find them on the google AdMob website, I personally suggest to add them all, before I added them my code didn't work
func addBannerViewToView(_ bannerView: GADBannerView) {
bannerView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(bannerView)
if #available(iOS 11.0, *) {
// In iOS 11, we need to constrain the view to the safe area.
positionBannerViewFullWidthAtBottomOfSafeArea(bannerView)
}
else {
// In lower iOS versions, safe area is not available so we use
// bottom layout guide and view edges.
positionBannerViewFullWidthAtBottomOfView(bannerView)
}
}
// MARK: - view positioning
@available (iOS 11, *)
func positionBannerViewFullWidthAtBottomOfSafeArea(_ bannerView: UIView) {
// Position the banner. Stick it to the bottom of the Safe Area.
// Make it constrained to the edges of the safe area.
let guide = view.safeAreaLayoutGuide
NSLayoutConstraint.activate([
guide.leftAnchor.constraint(equalTo: bannerView.leftAnchor),
guide.rightAnchor.constraint(equalTo: bannerView.rightAnchor),
guide.bottomAnchor.constraint(equalTo: bannerView.bottomAnchor)
])
}
func positionBannerViewFullWidthAtBottomOfView(_ bannerView: UIView) {
view.addConstraint(NSLayoutConstraint(item: bannerView,
attribute: .leading,
relatedBy: .equal,
toItem: view,
attribute: .leading,
multiplier: 1,
constant: 0))
view.addConstraint(NSLayoutConstraint(item: bannerView,
attribute: .trailing,
relatedBy: .equal,
toItem: view,
attribute: .trailing,
multiplier: 1,
constant: 0))
view.addConstraint(NSLayoutConstraint(item: bannerView,
attribute: .bottom,
relatedBy: .equal,
toItem: bottomLayoutGuide,
attribute: .top,
multiplier: 1,
constant: 0))
}
/// Tells the delegate an ad request loaded an ad.
func adViewDidReceiveAd(_ bannerView: GADBannerView) {
print("adViewDidReceiveAd")
addBannerViewToView(bannerView)
bannerView.alpha = 0
UIView.animate(withDuration: 1, animations: {
bannerView.alpha = 1
})
}
/// 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")
}
Don't forget to set GADBannerViewDelegate in your class.
