Banner view ads not fetching from apple

Banner view ads not fetching from apple

I followed this tutorial but the ads do not show the way it does in most
apps.
Here is the code for handling the ads
-(void) bannerViewDidLoadAd:(ADBannerView *)banner {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1];
[banner setAlpha:1.0];
[UIView commitAnimations];
NSLog(@"view did load");
}
-(void) bannerView:(ADBannerView *)banner
didFailToReceiveAdWithError:(NSError *)error {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1];
[banner setAlpha:0.0];
[UIView commitAnimations];
NSLog(@"failed to receive ad");
NSLog(@"Error: %@ %@", error, [error userInfo]);
}
When I run it I get the following output:
2013-08-27 15:03:45.154 The Ultimate DateABase[8642:c07] failed to receive ad
