使用場景
一些App通過手機號碼來推薦好友，如 微博、支付寶
首先客戶端會獲取通訊錄中的所有手機號然后將這些手機號提交到App服務器中，服務器會查找每個手機號對應的App賬號如QQ號碼返回到客戶端，然后客戶端根據服務器返回的賬號列表來推薦好友。
方案一：AddressBookUI.framework框架
提供了聯系人列表界面、聯系人詳情界面、添加聯系人界面等
一般用于選擇聯系人
方案二：AddressBook.framework框架：
沒有提供UI界面，需要自己搭建聯系人界面
純C語言的API， 僅僅是獲得聯系人數據
大部分數據類型是Core Foundation
從iOS6 開始，需要得到用戶的授權才能訪問通訊錄
方案三：第三方框架：RHAddressBook
對 AddressBook.framework 進行封裝
方案四：iOS9.0最新通訊錄框架
ContactsUI.framework : 方案1的替代品，特點： 面向對象，使用簡單，有界面
Contacts.framework： 方案2的替代品， 特點：面向對象，使用簡單，五界面
創建選擇聯系人的控制器
設置代理：用來接收用戶選擇的聯系人信息
彈出聯系人控制器
實現代理方法
在對應的代理方法中獲取聯系人信息
請求授權
判斷授權狀態如果已授權則繼續，如果未授權則提示用戶
創建通訊錄對象
從通訊錄中獲取所有的聯系人
遍歷所有的聯系人
釋放不再使用的對象

該框架使用的MRC來管理內存的，如果直接將源代碼拖入進去需要為每個文件設置編譯標記：-fno-objc-arc， 設置完還會報錯，該項目使用的一些方法過于古老，很多都不支持了，所以這種方式不采用； 可以將該項目打成靜態庫的方式；也可以直接將項目拖入到自己的工程中作為一個依賴
直接將RHAddressBook.xcodeproj拖入到工程中
