Question

When I run my application I get this message for iAd banner view. What does it mean?

Error Domain=ADErrorDomain Code=3 \"The operation couldn’t be compl

Answer 1

You will randomly get this error message in Simulator or device, so that you can test your app and its behavior when no iAd is available (hidding the AdView, using another ad provider...). But it's not a bug from Simulator / iAd framework / iAd network: it's a feature to make better tests.

Moreover, you cannot get "real" iAds when deploying your app in test mode on test device. It has to be reviewed by Apple and downloaded from the AppStore.
