title: Understanding of how to use "Container View" in iOS Designer
body: <p>One can add a <code>Container View</code> on an existing view with the help of <code>iOS Designer</code>. A container view is placed on the existing view with an embed segue to a new added view controller. The new added view controller is responsible for the content of the container view.</p>
  
  <p>One problem is that you can't change the embed segue or create a new embed segue. The only way is described <a href="http://forums.xamarin.com/discussion/19128/container-view-in-xamarin-ios" rel="nofollow">here</a>. But how do you use that? I saw an <a href="http://sandmoose.com/post/35714028270/storyboards-with-custom-container-view-controllers" rel="nofollow">example</a> by exchanging the view controller in the container. That's not what I want. I want to display multiple view controllers in one container, but I only get this managed by code.</p>
  
  <p>So for what use cases is this <code>Container View</code> element?</p>
