title: Content positioning into a UIScrollView
body: <p>I'm trying to add a scroll view to an existing screen of my app to help scroll the screen upward when keyboard hides a text field into this view. </p>
  
  <p>I have added the scroll view as a subview of the main view in Interface Builder. Then I added all other objects as subviews to this scrollview. I have set the scroll view size to 320x460 with x=0 and y=0. Now, I notice the layout is broken and all objects (labels,text fields overlap in the same place). </p>
  
  <p>Do you know the proper way to position this scrollview in interface builder so that I can easily position the other objects?</p>
  
  <p>Thx for helping,</p>
