安装：配置
1：所需frame.work;
CFNetwork, SystemConfiguration, MobileCoreServices, CoreGraphics and libz.dylib libxml2.dylib
2: ASI Tests 须要 https://github.com/gh-unit/gh-unit/tree/master 然后导入 ：GHUnitIOS.framework
3:bulid setting Header search path 加入 /usr/include/libxml2
4：在 test/ASIDataCompareTest.m中有个 NStask错误，删除文件就可以；
5: 假设使用 Test文件加里面的东西。使用 GHUnitIOS.framework http://stackoverflow.com/questions/13925437/ghunitios-ghunit-h-file-not-found-in-xcode
