title: Implementing AdMob with lots of View Controllers
body: <p>I'm sorry for this newbie question but here it goes.  I'm just starting with iOS and implementing AdMob in my app. The app is running fine with the Ads working but I have four View Controllers and for the sake of test I just implement all theses methods in all View Controllers.</p>
  
  <pre><code>- (GADRequest *)createRequest
  - (void)adViewDidReceiveAd:(GADBannerView *)adView
  - (void)adView:(GADBannerView *)view
  </code></pre>
  
  <p>But imagine if I had 100 VC...There's a way to do it only in one file and import like a .h file? Yes, my OOP knowledge is limited and If somebody can help me I would appreciate. </p>
  
  <p>Thanks</p>
