iPhone iAd -- not getting callbacks to didFailToReceiveAdWithError

I am testing an iAd app on an iPod touch. My iPod is connected to the internet. In all my testing, I have only received one callback to didFailToReceiveAdWithError.

Here is the relevant code:

#ifdef mAppHasAds 
- (void)bannerViewDidLoadAd:(ADBannerView *)banner {
    NSLog (@"Triangle ad");
    bannerView.hidden = NO;
}

- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error {
    NSLog (@"No Triangle ad");
    bannerView.hidden = YES;
}
#endif

And here are some of the NSLogs I am seeing. Note that some of the timestamps are 1 minute or 1 min 30 sec apart. To me, this indicates that ads failed to arrive. But there was no callback.

I see it differently -- If your app failed to receive an ad, it would log "No Triangle Ad" -- but it never does.

I think your code "bannerView.hidden = NO" isn't pushing the view to the display.

Want to try this instead?

- (void)bannerViewDidLoadAd:(ADBannerView *)banner
{
 if (!self.bannerIsVisible)
 {
   [UIView beginAnimations:@"animateAdBannerOn" context:NULL];
   // banner is invisible now and moved out of the screen on 50 px
   banner.frame = CGRectOffset(banner.frame, 0, 50);
   [UIView commitAnimations];
   self.bannerIsVisible = YES;
 }
}
