title: How to add a subview that contains an iAd Banner View?
body: <p>I have a tab bar with 3 view controllers and I want to implement iAds to the app.</p>
  
  <p>I have been searching and I read that a good way to implement the iAds is to create them apart, like in another ViewController, so that's what I did. I have my First, Second and ThirdViewController and an AdBannerController. I got the Bees 4 Honey iAd tutorial (http://bees4honey.com/blog/tutorial/how-to-add-iad-banner-in-iphoneipad-app/) and put the iAd in this view controller (AdBannerController). So, now I think I have to add a sub view to each ViewController (First, second and third), but I don't know how. I would be really thankful if you can help me (and if you know a better way to implement the iAds to a tabbar app, thanks a lot too!). </p>
  
  <p>Thanks.</p>
