/**
|
|
* @description
|
|
* The NavController is a navigation stack View Controller modelled off of
|
|
* UINavigationController from Cocoa Touch. With the Nav Controller, you can
|
|
* "push" new "pages" on to the navigation stack, and then pop them off to go
|
|
* back. The NavController controls a navigation bar with a back button and title
|
|
* which updates as the pages switch.
|
|
*
|
|
* The NavController makes sure to not recycle scopes of old pages
|
|
* so that a pop will still show the same state that the user left.
|
|
*
|
|
* However, once a page is popped, its scope is destroyed and will have to be
|
|
* recreated then next time it is pushed.
|
|
