title: How to add a scroll view to the existing view controller?
body: <p>I have added a lot of ui elements in my controller and I have also done the web service part in the implementation code. It seems like my default screen size view controller is not sufficient for me to display the information. Is it possible to add a scroll view to the existing controller and if yes please give an idea or an example, so that I can add some more ui elements.</p>
  
  <p>Thanks in advance. </p>
