使用场景
一些App通过手机号码来推荐好友，如 微博、支付宝
首先客户端会获取通讯录中的所有手机号然后将这些手机号提交到App服务器中，服务器会查找每个手机号对应的App账号如QQ号码返回到客户端，然后客户端根据服务器返回的账号列表来推荐好友。
获取联系人方式
方案一：AddressBookUI.framework框架
提供了联系人列表界面、联系人详情界面、添加联系人界面等
一般用于选择联系人
方案二：AddressBook.framework框架：
没有提供UI界面，需要自己搭建联系人界面
纯C语言的API， 仅仅是获得联系人数据
大部分数据类型是Core Foundation
从iOS6 开始，需要得到用户的授权才能访问通讯录
方案三：第三方框架：RHAddressBook
对 AddressBook.framework 进行封装
方案四：iOS9.0最新通讯录框架
ContactsUI.framework : 方案1的替代品，特点： 面向对象，使用简单，有界面
Contacts.framework： 方案2的替代品， 特点：面向对象，使用简单，五界面
方案一：AddressBookUI.framework
实现步骤：
创建选择联系人的控制器
设置代理：用来接收用户选择的联系人信息
弹出联系人控制器
实现代理方法
在对应的代理方法中获取联系人信息
AddressBook.frame
实现步骤：
请求授权
判断授权状态如果已授权则继续，如果未授权则提示用户
创建通讯录对象
从通讯录中获取所有的联系人
遍历所有的联系人
释放不再使用的对象
AddreesBook.framework具体实现:
1. AppDelegate 应用启动时请求授权
#import"AppDelegate.h"#import@interfaceAppDelegate()@end@implementationAppDelegate- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {// Override point for customization after application launch.[selfrequestAuthorizationAddressBook];returnYES;}- (void)requestAuthorizationAddressBook {// 判断是否授权ABAuthorizationStatus authorizationStatus = ABAddressBookGetAuthorizationStatus();if(authorizationStatus == kABAuthorizationStatusNotDetermined) {// 请求授权ABAddressBookRef addressBookRef = ABAddressBookCreate(); ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(boolgranted, CFErrorRef error) {if(granted) {// 授权成功}else{// 授权失败NSLog(@"授权失败！"); } }); }}@end

4. 运行结果
第三方框架：RHAddressBook
https://github.com/heardrwt/RHAddressBook
该框架使用的MRC来管理内存的，如果直接将源代码拖入进去需要为每个文件设置编译标记：-fno-objc-arc， 设置完还会报错，该项目使用的一些方法过于古老，很多都不支持了，所以这种方式不采用； 可以将该项目打成静态库的方式；也可以直接将项目拖入到自己的工程中作为一个依赖
直接将RHAddressBook.xcodeproj拖入到工程中
添加Target Dependencies和Link Binary With Libraries
Build Settings—> Other Linker Flags : -ObjC
用于解决系统分类找不到方法的错误
