I made an iPhone Application which uses iAd. On the iPhone Simulator and the Device it works fine. It already is on the App Store.
Today, one of my
As an alternative answer, which just worked for me... because I forgot about it. I had set Fill Rate of iAds in the Settings/Developer page to 0% some long time ago... DOOH!
So please triple check there.
I had a similar problem. The only solution for me was to make the application universal. Once the application was universal the iAds start working.
You might notice that even some of applications from iAds suite form Apple did not work. And they mention somehting in this regard in their description here:
http://developer.apple.com/library/ios/#samplecode/iAdSuite/Introduction/Intro.html
The BasicBanner and ContainerBanner are configured to support both iPhone and iPad idioms, the TabbedBanner and NavigationBanner to support only the iPhone idiom, and the SplitViewBanner to support only the iPad idiom.
The only difference I have found was the universal vs. iPhone app settings (target->SUmmary->Device combobox).
Hoever, if I remember correctly, my - (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
was called. The error was saying something about that there is no available iAds.
Also, I tried only on iOS5 (both simulator and device).
Hope this will help you a little ;)
Update: Also check this SO question in case you are using some older SDK: Is iAds not available for iPad apps?
If you want to use iAd, you pretty much need to be a universal app. My iPhone-only iAd app when run on an iPad in compatibility mode (on the simulator or on a real iPad) would call bannerViewDidLoadAd but then displayed a blank space instead of an ad. The Apple "iAd Implementation Best Practices" doc says:
Create Universal Apps
To ensure your app is capable of displaying iAd banners for all your users,
make sure you’ve developed a universal app that supports all possible devices.
**iPhone apps running in compatibility mode on iPad will not display a test ad
in development or live ads in deployed apps.**
