篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了最新 AFNetworking 3.0 简单实用封装相关的知识,希望对你有一定的参考价值。
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
