Answer 1

Ok, I found the solution.
I was almost there but not quite. The problem IS setting the delegate to nil, but the place was wrong.
This is how I solved it:
- (void)viewDidLoad {
[super viewDidLoad];
adMobAd = [AdMobView requestAdWithDelegate:self]; // start a new ad request
[adMobAd retain];
}
- (void)viewDidUnload {
//Nothing to do here
}
- (void)dealloc {
//THIS IS THE IMPORTANT STUFF
if (adMobAd != nil){
adMobAd.delegate = nil;
}
[adMobAd release];
[super dealloc];
}
Moving the "liberation" of the delegate to the dealloc block has fixed the problem for me.
Hope it helps!
