好记性不如烂笔头，今天记录一下CocoaPods创建私有Pod库方法，以码云作为第三方私有仓库为例。
1、创建一个git仓库用来做内部私有库的Spec Repo，命名为Pods(自己喜欢怎么命名都可以)，如下图：
image.png
注意：一定要勾选为私有
2、打开终端执行以下代码（因为现在创建的是一个空仓库，执行以下命令是为了创建README.md）:
mkdir Pods
cd Pods
git init
touch README.md
git add README.md
git commit -m "first commit"
git remote add origin https://gitee.com/xxxx/Pods.git
git push -u origin master
注意：其中https://gitee.com/xxxx/Pods.git就是这个仓库的地址
当执行完毕以上的命令以后，回到仓库页面刷新，你会看到以下页面，说明成功创建README.md并上传到了git仓库了。

到这一步，存储内部私有库的Spec Repo的git仓库就算建立完毕了。
下面开始创建真正的私有库。
1、首先在第三方git的仓库，命名为SLKit，步骤跟上面的1和2一样的。
执行完以上的步骤，然后把项目拉下来本地，然后在本地进行开发。
我在工程目录下创建了SLKit文件夹，在这个文件夹下创建了NSString+HDDmd5.h和NSString+HDDmd5.m文件，如下图：

编辑完成以后，在终端执行以下命令把代码提交到远程仓库：
cd 到目标文件
git add -A
git commit -m "增加NSString+HDDmd5.h和NSString+HDDmd5.m文件"
git push origin master
2、可以通过如下代码创建podspec文件
pod spec create SLKit
3、用Xcode 打开SLKit.podspec文件进行编辑

编辑SLKit.podspec文件
#
# Be sure to run `pod spec lint SLKit.podspec' to ensure this is a
# valid spec and to remove all comments including this before submitting the spec.
#
# To learn more about Podspec attributes see https://guides.cocoapods.org/syntax/podspec.html
# To see working Podspecs in the CocoaPods repo see https://github.com/CocoaPods/Specs/
#
Pod::Spec.new do |spec|
# ――― Spec Metadata ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# These will help people to find your library, and whilst it
# can feel like a chore to fill in it's definitely to your advantage. The
# summary should be tweet-length, and the description more in depth.
#
#项目名称
spec.name = "SLKit"
#项目版本号
spec.version = "1.0.0"
#项目的描述
spec.summary = "SLKit私有库."
# This description is used to generate tags and improve search results.
# * Think: What does it do? Why did you write it? What is the focus?
# * Try to keep it short, snappy and to the point.
# * Write the description between the DESC delimiters below.
# * Finally, don't worry about the indent, CocoaPods strips it!
# 项目的描述
spec.description = <<-DESC
SLKit私有库
DESC
#项目的主页
spec.homepage = "https://gitee.com/snailLi"
# spec.screenshots = "www.example.com/screenshots_1.gif", "www.example.com/screenshots_2.gif"
# ――― Spec License ――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# Licensing your code is important. See https://choosealicense.com for more info.
# CocoaPods will detect a license file if there is a named LICENSE*
# Popular ones are 'MIT', 'BSD' and 'Apache License, Version 2.0'.
#
# 验证许可证
spec.license = "MIT"
# spec.license = { :type => "MIT", :file => "FILE_LICENSE" }
# ――― Author Metadata ――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# Specify the authors of the library, with email addresses. Email addresses
# of the authors are extracted from the SCM log. E.g. $ git log. CocoaPods also
# accepts just a name if you'd rather not provide an email address.
#
# Specify a social_media_url where others can refer to, for example a twitter
# profile URL.
#
#作者
spec.author = { "xxxxx" => "[email protected]" }
# Or just: spec.author = "xxxxx"
# spec.authors = { "xxxxxx" => "[email protected]" }
# spec.social_media_url = "https://xxxxxx"
# ――― Platform Specifics ――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# If this Pod runs only on iOS or OS X, then specify the platform and
# the deployment target. You can optionally include the target after the platform.
#
# 适配的系统
spec.platform = :iOS
#适配系统的最低版本
spec.platform = :ios, "10.0"
# When using multiple platforms
# spec.ios.deployment_target = "5.0"
# spec.osx.deployment_target = "10.7"
# spec.watchos.deployment_target = "2.0"
# spec.tvos.deployment_target = "9.0"
# ――― Source Location ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# Specify the location from where the source should be retrieved.
# Supports git, hg, bzr, svn and HTTP.
#
#项目git仓库的地址
spec.source = { :git => "https://gitee.com/snailLi/SLKit.git", :tag => "#{spec.version}" }
# ――― Source Code ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# CocoaPods is smart about how it includes source code. For source files
# giving a folder will include any swift, h, m, mm, c & cpp files.
# For header files it will include any header in the folder.
# Not including the public_header_files will make all headers public.
#
#pod时需要集成的文件 一定要加上swift 不然报错
spec.source_files = "SLKit/SLKit/*.{h,m,swift}"
spec.exclude_files = "Classes/Exclude"
# spec.public_header_files = "Classes/**/*.h"
# ――― Resources ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# A list of resources included with the Pod. These are copied into the
# target bundle with a build phase script. Anything else will be cleaned.
# You can preserve files from being cleaned, please don't preserve
# non-essential files like tests, examples and documentation.
#
# spec.resource = "icon.png"
# spec.resources = "Resources/*.png"
# spec.preserve_paths = "FilesToSave", "MoreFilesToSave"
# ――― Project Linking ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# Link your library with frameworks, or libraries. Libraries do not include
# the lib prefix of their name.
#
# spec.framework = "SomeFramework"
# spec.frameworks = "SomeFramework", "AnotherFramework"
# spec.library = "iconv"
# spec.libraries = "iconv", "xml2"
# ――― Project Settings ――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# If your library depends on compiler flags you can set them in the xcconfig hash
# where they will only apply to your library. If you depend on other Podspecs
# you can include multiple dependencies to ensure it works.
#是否要求arc（有部分非arc文件情况未考证）
spec.requires_arc = true
# spec.xcconfig = { "HEADER_SEARCH_PATHS" => "$(SDKROOT)/usr/include/libxml2" }
# spec.dependency "JSONKit", "~> 1.4"
end
.podspec文件具体简介可以参考这边文章 https://www.jianshu.com/p/5ca47f960379
4、本地验证.podspec文件，打开终端执行以下命令：
pod lib lint SLKit.podspec --allow-warnings
如果看到 SLKit passed validation. 说明本地杨峥通过了
5、提交.podspec文件到远程git仓库并打标签，执行以下命令：
git add -A && git commit -m "version 1.0.0"
git tag '1.0.0' //和上面.podspec一致
git push --tags
git push origin master
6、提交完毕以后，执行以下命令进行远程验证.podspec文件
pod spec lint SLKit.podspec --allow-warnings
如果出现了SLKit.podspec passed validation. 说明远程验证成功了
7、执行以下命令将Pods添加到本地repo
pod repo add Pods https://gitee.com/snailLi/Pods.git
添加成功后可以在/.cocoapods/repos/目录下可以看到官方的specs:master和刚刚加入的specs:Pods
8、执行以下命令，将SLKit加入私有Sepc repo中
pod repo push Pods SLKit.podspec --allow-warnings
出现如下图说明添加成功了

新建工程验证是否可以正确pod下来
Podfile文件填写如下：

成功pod下来SLKit

至此，简单的CocoaPods创建私有Pod库就制作完毕了
