MDCAppBarNavigationController


@interface MDCAppBarNavigationController : UINavigationController

A custom navigation controller instance that auto-injects App Bar instances into pushed view controllers.

If a pushed view controller already has an App Bar or a Flexible Header then the navigation controller will not inject a new App Bar.

To theme the injected App Bar, implement the delegate’s -appBarNavigationController:willAddAppBar:asChildOfViewController: API.

Note

If you use the initWithRootViewController: API you will not have been able to provide a delegate yet. In this case, use the -appBarForViewController: API to retrieve the injected App Bar for your root view controller and execute your delegate logic on the returned result, if any.
