iAd appears before it is loaded in iOS using subviews - ios

Question

Hello I have an issue where my ads appear before they are even loaded.
I got this
#pragma mark iAd Delegate Methods
- (AppDelegate *) appdelegate {
return (AppDelegate *)[[UIApplication sharedApplication] delegate];
}
-(void) viewWillAppear:(BOOL)animated{
//this part set alpha 0 does nothing
[_UIiAD setAlpha:0];
_UIiAD = [[self appdelegate] UIiAD];
_UIiAD.delegate = self;
[_UIiAD setFrame:CGRectMake(0,470,320,50)];
[self.view addSubview:_UIiAD];
}
-(void)bannerViewDidLoadAd:(ADBannerView *)banner{
NSLog(#"ads loaded");
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1];
[_UIiAD setAlpha:1];
[UIView commitAnimations];
}
-(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error{
NSLog(#"ads not loaded");
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1];
[_UIiAD setAlpha:0];
[UIView commitAnimations];
}
I have tried to stick
[_UIiAD setAlpha:0];
In various parts of my code, but still same issue.

If your AdBannerView has been initialized outside of this snippet (presumably in AppDelegate from what you show in your viewWillAppear: code), it can still load ads even before it has a delegate.
Instead of programmatically adding the iAd banner as a subview after creating it somewhere else, have you tried adding it using Interface Builder and just using the code to hide/unhide based on whether or not it's received content.
