title: Set margins of view xcode
body: <p>I have been programming android apps for a bit, and I am now making an iphone app.  I want to make margins for my view.  I would not like to explain my exact situation, but if someone helps me with this I'll be able to figure out what I need to do.</p>
  
  <p>I have two views, I want the first view to take up the entire screen.  Then I want another view to always be, lets say 20 pixels from the edge of the screen on all four sides.  Is there a simple way to do that in xcode?</p>
  
  <p>Thanks</p>
