前言
- 函数式+链式（以
为例）
//例如
make.left.equalTo(self.view).offset(10)
//像这样一直，把需要执行的代码一直写下去，就可以称为链式。
//像这样通过
去调用函数，返回自身，可以简单的理解为就是函数式。
- GCDAsyncSocket是一个写的很好的Socket框架，但是感觉使用代理写起来比较麻烦，另外基于学习函数式+链式编程，所以顺便简单封装一下GCDAsyncSocket库。写的不好的话，请大神指教。

项目大致结构（还没有包含GCDAsyncSocket所有功能，但我会持续研究）

主要的内容（只贴.h文件，完整项目可以在本文最后调到Github下载）
