写在前面
说明：
两个私有库：
一个是私有代码库，存放需要pod封装的代码
一个是私有索引库，模拟cocoapods公共索引的库，通过这个索引找到私有代码库
步骤
1，根据命令提示创建工程
$ pod lib create CocoapodDemo
根据提问、提示创建一个demo工程
CocoapodDemo/CocoapodDemo/Classes中存放的就是Pod要包装的files
2，上传源码
把这个工程里的代码上传到远程私有代码库（没有的话新建一个）
3，创建索引库
新建一个远程仓库用于存放自己的私有库的 .podspec文件（私有索引库）， 例如 [email protected]:yongqianvip/privatePodspec.git
通过下面的命令创建本地私有pod索引库
$ pod repo add privatePodspec [email protected]:yongqianvip/privatePodspec.git
如果不行换用https://开头的链接 ，然后再看 .cocoapods/repos/ 文件夹下就多了一个privatePodspec文件夹，里面的master文件夹是pod公共索引库，包含成千上万的pod索引，privatePodspec就是模拟这个公共索引库的私有索引库
4，功能实现
到这里，私有代码库和私有索引库都创建完毕，接下来就是功能实现，想要实现什么功能，把相应的功能实现文件、头文件等放入CocoapodDemo/CocoapodDemo/Classes目录下，在Example文件夹下的工程中进行测试，然后一并上传到远程代码库
5，编辑CocoapodDemo.podspec文件
这个应该无需过多解释，主要配置好source和source_files，更多参数送传送门http://guides.cocoapods.org/syntax/podspec.html
6，验证CocoapodDemo.podspec文件
$ pod lib lint
在CocoapodDemo.podspec文件所在目录下执行上面的命令，如果验证通过会显示
如果有
ERROR一定要先修改错误，如果是可以忽略的警告加
--allow-warnings 参数
文末列出了几个错误，可以参考，也欢迎补充。。。
7，打tag提交代码
podspec验证通过之后，私有代码库打tag提交
$ git tag '0.0.1'
$ git push --tags
tag 要和 .podspec文件中的version一致
8，添加到本地索引库
$ pod repo push privatePodspec CocoapodDemo.podspec
注意： 如果lint的时候添加了 --allow-warnings --use-libraries 等参数的话，push的时候也要加上
9，验证
$ pod search RRCLogin
如果之前步骤都成功，但是验证环节报错
[!] Unable to find a pod with name, author, summary, or description matching 'RRCLogin'
可能是缓存的问题，清理
cocoapod的
search缓存
$ rm ~/Library/Caches/CocoaPods/search_index.json
再执行search（清理search的缓存之后再搜索时间会有点儿长）
10，使用我们上传的私有pod
在需要引用这个库的工程的Podfile中添加
source 'https://github.com/CocoaPods/Specs.git'
source 'https://github.com/yongqianvip/privatePodspec.git'
这是为了告诉pod，检索依赖的时候既要检索公共索引库，咱们本地的私有索引库也要检索
总结
这里是借助公开库 模拟私有库的pod封装，我们的索引没有推送到cocoapod远程库，假想一下，如果我们的这两个仓库都是私有的，那么别人就搜不到我们的代码，就实现了真正的私有pod

这个错误目前还不清楚原因，初步推测是环境变量的问题，为了解决这个错误，我换了台电脑、我换了台电脑、我换了台电脑

这个错误是文件引用的问题，我的代码中用到了JSONModel，引用的方式是 #import "JSONModel.h”，但是JSONModel是通过s.dependency 'JSONModel’, ‘~> 1.5.1’的方式，引入的，那么我自己的代码中使用JSONModel就应该是用尖括号的形式引入了
#import 这是不对的，应该用#import ，否则会有下边的错

这个错误是路径的问题，我的代码中用到了JSONModel，引用的方式是 #import ，改成#import 就可以了

依赖了其他库，lint 检查的时候添加后缀
$ pod lib lint --use-libraries
