iAd error “Ad inventory unavailable”

Question

I\'m adding iAd to my app. Now, in simulator, it works well but when I load it on a device (v4.1) the ADBannerViewDelegate calls bannerView:didFailToReceiveAdWi

Answer 1

According to the ADBannerView class reference of Apple's documantation iOS Developer Library:

enum {
ADErrorUnknown = 0,
ADErrorServerFailure = 1,
ADErrorLoadingThrottled = 2,
ADErrorInventoryUnavailable = 3,
ADErrorConfigurationError = 4,
ADErrorBannerVisibleWithoutContent = 5,
ADErrorApplicationInactive = 6
};
typedef NSUInteger ADError;

//ADErrorInventoryUnavailable
//Indicates that no advertisements are currently available to download.
//Available in iOS 4.0 and later.
//Declared in ADBannerView.h.

Therefore it is an exception caused by the server side of the iAd; not the code itself.
