iAd Banner Question

Question

I am getting this warning when I switch views (which are just different themes) in my app. Any ideas, suggestions on why the app is not loading?

2011-04-25 16:14:20.211 MyApp [4121:40b] ADBannerView: WARNING A banner view (0x631bb30) has an ad but may be obscured. This message is only printed once per banner view.

It appears that when the view switches, the other view is just in the background, any ideas on how to do this.

** Note there is an excellent example on Apple's developer site, called iADSuite

Answer 1

This message means that a banner has a part that is or it is fully not visible. If you do read the iAd documentation from Apple you will notice that they recommend having only one iAd instance which you should use for all your views (uiviewcontrollers)

how I do iAds in my apps is - I have 1 singleton class which shows the iAd banner (thus I follow Apple's recommendation to have only 1 iAd instance). In all my viewcontrollers in the viewDidLoad method I show the iAd view from my singleton class and in viewWillDisappear I remove the iAd view from the viewcontroller.

This way the banner view is always visible in only 1 viewcontroller - therefore it never is "obscured" and such.

I hope this explanation helps you out :)
