If you are not familiar with the code and you want to find ViewController coresponding to given view, then you can try:

1. Run app in debug
2. Navigate to screen
3. Start View inspector
4. Grab the View you want to find (or a child view even better)
5. From the right pane get the address (e.g. 0x7fe523bd3000)
6. In debug console start writing commands:

    po (UIView *)0x7fe523bd3000
    po [(UIView *)0x7fe523bd3000 nextResponder]
    po [[(UIView *)0x7fe523bd3000 nextResponder] nextResponder]
    po [[[(UIView *)0x7fe523bd3000 nextResponder] nextResponder] nextResponder]
    ...

In most cases you will get UIView, but from time to time there will be UIViewController based class.
