title: How to switch views by buttons on iPhone?
body: <p>I want to switch 3 views and let them switch from 1-2-3. The first view is to let users input name and password, the second view will show his information to let him confirm and the third view will show him a list of options so he can choose what to do next.</p>
  
  <p>The problem is how to switch these views? If I use a navigation controll to switch views, how can I add textfield in it so users can input their infomation?</p>
