Error trying to get iAds off screen

Question

Trying to make iAds go off screen when no ad is loaded, as per Apple's request. They gave me this code:

- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
 if (self.bannerIsVisible)
 {
  [UIView beginAnimations:@"animateAdBannerOff" context:NULL];
   // assumes the banner view is at the top of the screen.
  banner.frame = CGRectOffset(banner.frame, 0, -50);
  [UIView commitAnimations];
  self.bannerIsVisible = NO;
 }
}

I made my view a delegate for iAds and whatnot, but whenever I try to compile, I get:

"Request for member 'bannerIsVisible' in something not a structure or union

I tried adding a BOOL bannerIsVisible, but it just made things worse

Answer 1

To use self.bannerIsVisible you need to have bannerIsVisible declared as a property.
