View Controller Catalog for iOS

View controllers present and manage a hierarchy of views. The UIKit framework includes classes for view controllers you can use to set up many of the common user interaction idioms in iOS. You use these view controllers with any custom view controllers you may need to build your app’s user interface. This document describes how to use the view controllers that are provided by the UIKit framework.

Familiarize yourself with the view controllers that you can use in your app. Although you can build an app entirely from custom view controllers, using the provided view controllers reduces the amount of code you have to write and helps you maintain a consistent user experience.
