1.在github 上新建一个repository
2.在本机cd到存放这个库的文件夹下，终端输入pod lib create ShawPodDemo
3.创建pod会问几个问题，我这里是用OC写的代码，后续制作与Swift稍有不同，根据自己情况填写即可。
4.创建完毕之后，会自动创建一个ShawPodDemo文件夹，里面有pod的相关信息，并且自动打开此project。
5.修改ShawPodDemo.podspec文件
6.ok到这一步 .podspec文件就配置完成了 7.验证本地.podspec 文件的有效性 输入命令: $pod lib lint ShawPodDemo.podspec
-> ShawPodDemo (0.1.0) - WARN | url: The URL (github.com/mr-show-201…) is not reachable.
[!] ShawPodDemo did not pass validation, due to 1 warning (but you can use --allow-warnings to ignore it) and all results apply only to public specs, but you can use --private to ignore them if linting the specification for a private pod.
You can use the --no-clean option to inspect any issue.
8.如果有 Error这需要更改 error。如果有 warning, 但有不改正需要执行下面的命令：
$ pod lib lint ShawPodDemo.podspec --allow-warnings
9.如果提示：[!] You need to run pod trunk register to register a session first.
那么在输入：pod trunk register 'XXXo@sina.cn' 'name'
直接输入 pod trunk register 'XXXo@sina.cn'
会提示[!] {"name"=>["is not present"]}
然后去邮箱进行确认！
10.再次执行 $pod lib lint ShawPodDemo.podspec
正常执行结果为：
Cloning spec repo ShawPodDemo from https://github.com/mr-show-2017/ShawPodDemo.git
