自荐亲自写的一套http訪问类库推荐给大家使用。
本人在开发过程中，由于各种原因。
自己开发了一套ＨＴＴＰ訪问工具。该工具借监了眼下大家都使和的ＡＳＩ类库。个人感认为ＡＳＩ里面太多的控制及逻辑变量都写在同一个类中。没有非常好的规划好。同一时候可能是由于多个人的改动，使得ＡＳＩ不同的版本号出现了不同的兼容方式。
同一时候也不可避免的增辑了对该代码的维护。
出于本人的开发经验自己写了一套这种类库，基本上与ＡＳＩ的功能上差不太多，可是对存在的未知ＢＵＧ及使用过程中出现的问题，也希望各读者在使用时将ＢＵＧ反馈给我，以便修正。
同一时候我把这套原码放在我的GITHUB上。供大家使用。希望大家多多支持我。
ＧＩＴＨＵＢ地址：https://github.com/fengsh998/WebRequestComponent
最新改动已支持block回调。
该类库使用简单。代码通俗易懂。使用ＯＯＰ进行划分。使得结构更加清晰，更易维护。

类库的执行原理图：
类库说明：?
1．????????使用ＧＣＤ线程管理，使用异步请求方式（暂不支持同步请求）。
2．????????支持SSL,proxy(http,socket5),cookie。
3．????????支持http断点续传（下载）。支持上传、下载进度回调。
4．????????支持队列请求。并发请求，组请求。
5．????????支持常见http请求,(POST,GET,DELETE,PUT)
6．????????支持重定向。
7．????????支持ＧＺＩＰ请求。
?
?
类库为非ＡＲＣ模式。
?
类库支持环境：
ＩＯＳ：
???????? ? Xcode 4.6以上。
?
Mac 10.8.5 ?xcode5.0以上。仅仅支持64位编译。32位机的没有做适配。所以低版本号的ＸＣ编译会有问题。
?
类库依赖：
依赖:
??? ios :UIKit.framework,mobileCoreServices.framework
??? mac :systemConfiguration.framework,cocoa.framework,appkit.framework
sdk依赖(ios,mac共同依赖):CFNewwork.framework,libz.dylib,Foundation.framework
