cocoapods 上传私有库或者远程库遇见的问题汇总

一、本地验证报错 $ pod lib lint

   localhost:XTBMain liuyihua$ pod lib lint
   -> XTBMain (0.1.3)
      - ERROR | [iOS] unknown: Encountered an unknown error (Unable to find a specification for `XTBBaseLib/Category` depended upon by `XTBMain`) during validation.

  [!] XTBMain did not pass validation, due to 1 error.
  [!] The validator for Swift projects uses Swift 3.0 by default, if you             are using a different version of swift you can use a `.swift-version` file to       set the version for your Pod. For example to use Swift 2.3, run: 
`echo "2.3" > .swift-version`.
  You can use the `--no-clean` option to inspect any issue.
  localhost:XTBMain liuyihua$ 

根据提示信息，我们了解到主要是因为
私有库的 'XTBBaseLib/Category '找不到
假如你已经创建好私有库A，并想在私有库B中使用私有库A，在库B的.podspec文件中你需要制定依赖：

  s.dependency 'pod projectName（A）', '~> version'

校验sepc可用性时，执行以下命令：

  pod sepc lint 文件名.podspec

发生错误：
- ERROR | [iOS] unknown: Encountered an unknown error (Unable to find a specification for XTBBaseLib/Category depended upon by XTBMain) during validation.

原因：

校验podspec文件时会到远程podspec库查找相关依赖，默认只会到官方specs库校验，此时需要指定远程specs库去校验。

解放方案：

  localhost:XTBMain liuyihua$ pod spec lint 文件名.podspec --sources='http://[privateLibName]/cocoaspecs.git,https://github.com/CocoaPods/Specs.git'

  -> XTBMain (0.1.3)

  XTBMain passed validation.
  localhost:XTBMain liuyihua$
