This part of the book describes view controllers, the major building blocks of an app’s interface and functionality, along with the views provided by the UIKit framework:

• Chapter 6 is about view controllers, the basis of an iOS app’s architecture. View controllers manage interface and respond to user actions. Most of your app’s code will be in a view controller.

• Chapter 7 is about scroll views, which let the user slide and zoom the interface.

• Chapter 8 explains table views, which are scroll views for navigating through data.

• Chapter 9 discusses collection views, which generalize table views, providing more flexible layout.

• Chapter 10 is about popovers, split views, iPad multitasking, drag and drop, and multiple windows on iPad.

• Chapter 11 describes how text is presented in an iOS app’s interface.

• Chapter 12 explains how to put a web browser inside your app.

• Chapter 13 describes all the remaining built-in UIKit interface objects.

• Chapter 14 is about various forms of modal dialog that can appear in front of an app’s interface.
