1.pod search AFN 如下错误
[!] CDN: trunk Repo update failed - 2 error(s):
CDN: trunk URL couldn't be downloaded: https://raw.githubusercontent.com/CocoaPods/Specs/master/Specs/4/a/2/afn/1.0.0/afn.podspec.json, error: Failed to open TCP connection to raw.githubusercontent.com:443 (Connection refused - connect(2) for "raw.githubusercontent.com" port 443)
CDN: trunk URL couldn't be downloaded: https://raw.githubusercontent.com/CocoaPods/Specs/master/Specs/4/a/2/afn/1.2.0/afn.podspec.json, error: Failed to open TCP connection to raw.githubusercontent.com:443 (Connection refused - connect(2) for "raw.githubusercontent.com" port 443)
执行pod repo remove trunk移除trunk源，pod search就都正常了
2.pod search 提示Unable to find a pod with name, author, summary, or description matching 'afnetworking'
解决方案：手动移除.cocoapods/repos目录下的master，然后Git clone 替换。
解决步骤：
1、在终端输入cd ~/.cocoapods/repos
2、移除master文件
3、输入命令：git clone --depth 1 https://github.com/CocoaPods/Specs.git master
4、等clone完成后，记得先删除search_index.json。pod search的时候会生成该文件，会主动记录之前搜索的行为存在本地，所以一般第二次搜索会比第一次快。
输入命令：rm ~/Library/Caches/CocoaPods/search_index.json回车
5、验证pod search 是否正常
