概要

本章主要简示了使用聚合云API获取指定手机号的归属地信息，这次找了个可以免费查询很多次的平台。开发主要根据聚合的官方文档，由于获取的查询结果是Json格式，所以涉及到了Json解析，但现在的IOS开发内置了Json解析库，所以事情就简单多了。

结果展示

流程概要

1.在聚合云平台上注册账号并创建应用，下载对应的SDK

2.查看SDK文档，根据文档描述创建应用添加头文件、库、框架，官当文档描述如下：

将JuheApisSDK.a以及头文件“include”文件夹添加到自己的工程中来，添加依赖库CoreTelephony.framework， AdSupport.framework, CoreLocation.framework。
   注：
      1,开发环境使用xCode6.0以上版本进行开发，
      2,将AppDelegate.m改为AppDelegate.mm，或者选中项目，在右侧的设置窗口中选择：TARGETS->XXX(项目名)->Build Phases->Link Binary With Libraries，添加libc++.dylib。

添加聚合数据SDK以及依赖的包(Objective-C)

3.把OpenID和AppKey放到工程里面，布局界面

4.构建请求URL，使用NSURLConnection发出请求，使用对应的代理保存获取的结果，并使用NSJSONSerialization解析请求结果，注意Json解析后的结果是个字典树类型。
