You can leave a 'blanking plate' by setting the following code in AdViewController.m:
Code:
- (void)awakeFromNib {
[self retain];
self.view.hidden = NO;
adMobAd = [AdMobView requestAdWithDelegate:self];
[adMobAd retain];
}
I guess you could leave the UIView in the same place across all views, which would leave a consistent box wherever you'd navigated to, but would fill up if Admob was 'ripe' for an ad?!?!?
