Firebase Banner Ad not loading

Question

I've implemented Firebase and originally had ad banners loading fine. But at some point along the way they have stopped showing up and i've tried everything i can think of. I have no idea what i could have changed as not much is different and certainly nothing with the Firebase or AdMob code has changed.

print("Google Mobile Ads SDK version: " + GADRequest.sdkVersion())
bannerView.adUnitID = "ca-app-pub-6956068899232786/3635179951"
bannerView.rootViewController = self
let request = GADRequest()
request.testDevices = [kGADSimulatorID]
bannerView.loadRequest(request)

I have also tried implementing the adViewDidReceiveAd() delegate function and i'm not seeing that get called either.

Answer 1

adViewDidReceiveAd没有调用，因为您忘记了添加

bannerView.delegate = self
