Introduction

The Address Book technology for iPhone OS provides a way to store people’s contact information and other personal information in a centralized database, and to share this information between applications. The technology has several parts:

• The Address Book framework provides access to the contact information.

• The Address Book UI framework provides the user interface to display the information.

• The Address Book database stores the information.

• The Contacts application provides a way for users to access their contact information.

This document covers the key concepts of the Address Book technology and explains the basic operations you can perform. When you add this technology to your application, users will be able to use the contact information that they use in other applications, such as Mail and Text, in your application. This document tells you how to do the following:

• Access the user’s Address Book database

• Prompt the user for contact information

• Display contact information to the user

• Make changes to the user’s Address Book database

To get the most out of this document, you should already be familiar with the basics of development for the iPhone, understand navigation controllers and view controllers, and understand delegation and protocols.
