title: Reusing view controllers
body: <p>I am unclear on how to reuse view controllers. If you have created a view controller subclass that does some stuff (doesn't really matter what it does, just that it does what you need in the view), can it be used with a different view or should it be subclassed again? </p>
  
  <p>In other words, if I need the exact same functionality in a view in a different part of my app, can I use the original view controller and just add the outlets from the new view? Or should I subclass the custom controller and give the view its "own" view controller?</p>
