title: Calling viewDidLoad while poping from a navigation class?
body: <p><strong>Interview question:</strong> For example, I have 3 classes A,B &amp; C. I navigate from A -> B -> C, while pushing <code>viewDidLoad</code> function calls automatically and during popping <code>viewWillAppear</code> get called. But would it be possible to call my <code>viewDidLoad</code> function while popping? </p>
