AFN常用的方法目前只用到这些（get，post，上传，下载，网络判断），每次都要创建的话感觉很麻烦，所以根据以往的项目简单的封装了一下，创建了一个继承于NSObject的HHttpManager工具类，网络请求的话基本这些就够用了。本人对block理解也并不是很深，哪里有问题欢迎提出.
ps：这几天在接各种SDK，极光推送，融云聊天，QQ，微信，微博，支付宝，不得不说一句，看官方的开发文档真的心累，过几天我会把目前用到的融云聊天，QQ（登录，分享），微信（登录，分享，支付），支付宝，微博（登录，分享），各自像AFN一样封装成一个工具类，再接入的话，就负责设置白名单，初始化，openURL的回调，然后就用工具类直接调用自己封装的方法就好了，登录，分享，支付等都会在一个文件里，能省事不少，也给没有接过微信支付宝SDK的新手参考参考。敬请期待0.0

以下是AFN的封装,都是类方法,直接调用就好.
