title: loadView Vs init method
body: <p>Please let me know at what times init and <code>loadView</code> method gets called.
  To my knowledge init method gets called only once when view is initialized and <code>loadView</code> is called anytime view is loaded. So, even if you are pushing a new view in the view stack and then popping it then also the <code>loadView</code> of the poped up view should get called. But when I am running my code in debugging mode, both of these methods are getting called once, irrespective of how many times I am loading the same screen. Please let me know if I am missing something.</p>
