This tutorial will teach you how to implement a UINavigationController object in your projects. By using this class, you will see how easy it is to provide your users with an intuitive way to navigate multiple screens of content. Enough talk, let's jump in!
A UINavigationController, often used in productivity applications, is responsible for managing a hierarchy of data and presenting that hierarchy to the end user. UINavigationController is a subclass of UIViewController that provides the developer with methods to push another view controller or remove the current view controller from a navigation stack. Each navigation controller has a root view controller that is the first view presented to the user and always lies beneath all the other view controllers in the navigation stack. The UINavigationController is not meant to be subclassed. Instead, it is instantiated directly and used to control the representation of view controllers.
