title: How do I create a simple two-screen iPhone app?
body: <p>I've gone through most of the example code and I still need some help.  I want to make an uber-simple app:  show one screen at startup with a label and a button.  click the button and we slide over to another screen (I suppose these are called views) which has another label and the "back" button in the top menu bar.  I just want to click back and forth between the two screens.</p>
  
  <p>How do I do this?</p>
