title: Thoughts about UINavigationController
body: <p>For my new app I'm planning to use UINavigationController to push/pop other controllers. </p>
  
  <p>Here is the scenario.</p>
  
  <p>Application is running. Via navigation controller I push first controller on the stack. The user make some selections and touch a button. Then navigation controller push the second controller and so on while the user reach the last controller which is sixth. Controllers from first until fifth will never be used again in the app. </p>
  
  <p>Is this the correct approach (using navigation controller) for such kind of app ?</p>
