I want to use AdMob in my app and I have 4 viewControllers (in 4 tab items) where I want to make it visible. The way the sample shows, every ViewController needs to make ins
The AppDelegate aproach is a nice approach but you should not retain the instance of the admob in every viewcontroller and release the same in the viewDidUnload method. Instead of doing this just add the admob's view in every viewcontroller's viewDidLoad method as a subview. In this manner there will be only one instance of the Admob's view in the AppDelegate.
Hope this helps you.
