I'm making a Tab Bar application. It has 3 ViewControllers. I learned how to put a working AdBannerView (because I'm kind of a newbie in this), so I put it on the FirstViewController. But then I realized that I want the ad to be present in all the 3 view controllers, not just on the first. So, I'm wondering if I can put the AdBannerView in like the MainWindow.xib or do I have to put one AdBannerView in each ViewController?
Thanks a lot if you can help me with this!
