下图为 文章的核心部分。介绍了两个 ios addressbook 和addressbook UI 系统frame，有一些不了解的，看看后再编程，会有很大帮助
In this section, we’ll provide a basic reference that supplements Apple’s own tutorial, but we suggest you read their guide for more extensive information. We’ll look at the Address Book frameworks, show how to access the Address Book’s properties, and explain how to use the Address Book UI.
Table 9.3 lists many of the most important classes in the frameworks. Table 9.3 The Address Book classes, the framework they belong to, and what they do
| Class |
Framework |
Summary |
| ABAddressBook |
Address Book |
Interface for accessing and changing the Address Book; may not be required if you use the Address Book UI framework |
| ABNewPersonViewController |
Address Book UI |
Interface for entering new record manually |
| ABPeoplePickerNavigationController |
Address Book UI |
Interface for selecting users and properties |
| ABPersonViewController |
Address Book UI |
Interface for displaying and editing records |
| ABUnknownPersonViewController |

| ABGroup |
Address Book |
Opaque type giving access to the records of groups |
| ABPerson |
Address Book |
Opaque type giving access to the records of individual people |
| ABRecord |
Address Book |
Record providing information on a person or group |
| ABMultiValue |
Address Book |
Type containing multiple values, each with its own label; its precise use is defined in ABPerson, where it’s applied to addresses, dates, phone numbers, instant messages, URLs, and related names |
| ABMutableMultiValue |
Address Book |
An ABMultiValue whose values can be modified |
Each of these classes contains numerous functions that can be used to build Address Book projects. We’ll talk about a few important functions and point you to the class references for the rest.
Accessing Address Book properties
As you’ll see shortly, the Address Book and Address Book UI frameworks ultimately provide different ways of accessing the Contacts data information: you might be working with the Address Book programmatically, or a user may be making selections through fancy UIs. Ways to select individual contacts may vary, but after a contact has been selected, you’ll generally use the same getter and setter functions to work with that record. These important functions are listed in table 9.4.
Table 9.4 Property setters and getters are among the most important functions in the Address Book.
