title: UIView vs Container View
body: <p>So here is the problem I am trying to solve.</p>
  
  <blockquote>
    <p>In each <code>viewController</code> I am trying to insert ads and the actual control elements. I finished couple of tutorial on raywenderlinch.com to understand that how people professionally put ads in their app. They used UIViews to have two views under mainview of view controller. So I completely understood that one <code>subview</code> hold the ads and another is holding actual app contents. if Ad is loaded take up the screen or else let other view have all available area. </p>

  <p>After I came back to xcode I started coding the way I learned there. but when I was dropping <code>UIView</code> on storyboard, I saw <code>containerView</code>, which I think was not present when the tutorial was written.<br>
  So I am here to ask about the both approach and their pros and cons.<br>
  So basically its <code>UIView</code> vs <code>ContainerView</code>. Which way I should do, and why ?<br>
  Any help would be greatly appreciated. </p>
