迁移项目必然要遇到旧的库在新的环境下水土不服的情况，首先遇到的难题是ASIHttpRequest。
Stackoverflow上找到了一个答案，如下：
It's very easy to use asi-http-request in an ARC environment without changing anything, simply follow these steps:
Simply create a static library target.Add asi-http-request files as required to the library targetConfigure the target to build without ARCAdd that static library as a dependency to your app targetAdd that static library in the build phases link section.可能是我操作有问题没有解决，于是尝试着躲避ARC，就想到了干脆把不想用ARC的文件都加上个flag“-fno-objc-arc”
搞定！
