Address Book UI and Address Book frameworks

iOS系統的關於操做通信錄的框架

Address Book UI中提供了系統的UI界面，方便開發

Address Book 提供了直接訪問Address Book數據庫的方法(知足某些開發中訪問Address Book中的數據的需求)

系統框架（Address Book UI）提供了四個控制器

ABPeoplePickerNavigationController prompts the user to select a person record from their address book.

ABPersonViewController displays a person record to the user and optionally allows editing.

ABNewPersonViewController prompts the user create a new person record.

ABUnknownPersonViewController prompts the user to complete a partial person record, optionally allows them to add it to the address book.

還有，調試的發現，App運行的時候，改變App的通信錄的受權，App會崩潰，查閱資料後發現是系統形成的。
