1、
git clone error: RPC failed; result=56, HTTP code = 200
解决办法：
git config --global http.postBuffer 524288000（尽量大）
http.postBufferMaximum size in bytes of the buffer used by smart HTTP transports when POSTing data to the remote system. For requests larger than this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is used to avoid creating a massive pack file locally. Default is 1 MiB, which is sufficient for most requests.
2、
$ pod install
Analyzing dependencies
[!] Unable to find a specification for `AFNetworking (~> 2.0)`
解决方法：没有进行 pod setup 吧，~/.cocoapods 里面是空的，没有办法寻找到相关的资源。
或者是 pod setup 失败了 需要 rm -rf ~/.cocoapods 删除重新 setup 一下，完毕之后这个文件夹大概有 100M，需要花费比较多时间。
