why?

I use 4.0 SDK and device's system version is iOS 3.1.3.

My codes is very simple that from examples which in "admob_iphone_sdk_20100818".


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!
