iAd runs well on simulator but not on device

Question

When I run my application I can see my iAd in the simulator, that is pre-filled with "Test Advertisement"

However, when I run the application on my device, the iAd area is blank, with no pre-filled ad.

Why is this?

Answer 1

Your answer may be in apple's documentation here. Basically you have to be set up properly for it and it will sometimes send errors on purpose. In addition, you may have to wait a few seconds for an ad to come up.

If you think things are in order, you can try Adding a NSLog() to the following delegate functions inside of the AdBannerViewDelegate protocol:

bannerViewDidLoadAd:

and

bannerView:didFailToReceiveAdWithError:

Make sure that you are set up to receive those delegate actions from the iAd banner view that isn't working.
