Make sure you have error handeling for if an ad cannot be displayed. If you dont have this it may cause a crash like this.

something like:

    - (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
        if (self.bannerIsVisible) {
             /* set banner not visible here
        }
