Overview

Navigation bar is a drop-in replacement for UINavigationBar with a few notable exceptions:

• No navigationItem stack. Instances of MDCNavigationBar must be explicitly provided with a back button. TODO(featherless): Explain how to create a back button with navigation bar once https://github.com/material-components/material-components-ios/issues/340 lands.

The MDCNavigationBar class is a composition of two button bars and a title label or title view. The left and right Button Bars are provided with the navigation item's corresponding bar button items.
