最新 AFNetworking 3.0 简单实用封装

AFNetworking 3.0 的到来使我们开发者又方便了许多，话不多说，直接上代码。

1.首先 引入框架AFNetworking框架

GitHub下载地址：https://github.com/AFNetworking/AFNetworking

AFNetworking官网地址：http://afnetworking.com

2.导入AFNetworking 支持框架

#import<MobileCoreServices/MobileCoreServices.h>

#import<SystemConfiguration/SystemConfiguration.h>

3.简单实用封装
