一、创建一个文件夹
mkdir Module
二、下载工程脚手架
pod lib create AaronSwift
AaronSwift是你要创建的组件工程的名称。安装过程中会提示你输入要下载工程的配置（如下：），依次输入：iOS、Swift、Yes、Quick、Yes，其中第二步如果想创建OC库，请输入ObjC。（各版本可能有不同，请根据提示输入）
Cloning `https://github.com/CocoaPods/pod-template.git` into `AaronSwift`.
Configuring AaronSwift template.
------------------------------
To get you started we need to ask a few questions, this should only take a minute.
If this is your first time we recommend running through with the guide:

( hold cmd and double click links to open in a browser. )

Analyzing dependencies
Downloading dependencies
Installing AaronSwift (0.1.0)
Installing FBSnapshotTestCase (2.1.4)
Installing Nimble (7.3.4)
Installing Nimble-Snapshots (6.3.0)
Installing Quick (1.2.0)
Generating Pods project
Integrating client project
[!] Please close any current Xcode sessions and use `AaronSwift.xcworkspace` for this project from now on.
Pod installation complete! There are 5 dependencies from the Podfile and 5 total pods installed.
[!] Automatically assigning platform `iOS` with version `9.3` on target `AaronSwift_Example` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.
Ace! you're ready to go!
We will start you off by opening your project in Xcode
open 'AaronSwift/Example/AaronSwift.xcworkspace'
To learn more about the template see `https://github.com/CocoaPods/pod-template.git`.
To learn more about creating a new pod, see `https://guides.cocoapods.org/making/making-a-cocoapod`.
三、创建Git Hub远程仓库
如果是公司的项目，需要运维同事搭建一个Git Lab仓库并创建项目。这里用Git Hub代替。在Git Hub上创建一个AaronSwift的项目。地址：https://github.com/AaronYin0514/AaronSwift
四、代码提交到远程仓库
进入工程目录
cd AaronSwift/
git init
git add .
git commit -m "first commit"
git remote add origin https://github.com/AaronYin0514/AaronSwift.git
git push -u origin master
五、编写代码
现在我们可以为私有库添加代码，位置是跟目录下的AaronSwift/Classes，我们的代码必须加到这个目录下。创建库时自动生成了ReplaceMe.swift文件，我们添加一些测试代码：
import Foundation
public struct RepleaceMeTest {
public func test() {
print("Test!")
}
}
六、提交代码
通过Source Tree管理代码，commit代码变动：
![AaronSwift_Git_]( "AaronSwift_Git_")
七、添加Tag
每一个版本我们需要添加一个Tag，如下图
![AaronSwift_Git_2]( "AaronSwift_Git_2")
八、检测配置文件是否填写正确
pod spec lint --allow-warnings
其中--allow-warnings参数代表忽略警告，如果你的代码在编译时有警告，如果不加这个参数就会报错。结果如下：
-> AaronSwift (0.1.0)
- WARN | [iOS] swift: The validator used Swift `4.0` by default because no Swift version was specified. To specify a Swift version during validation, add the `swift_versions` attribute in your podspec. Note that usage of a `.swift-version` file is now deprecated.
- NOTE | xcodebuild: note: Using new build system
- NOTE | [iOS] xcodebuild: note: Planning build
- NOTE | [iOS] xcodebuild: note: Constructing build description
- NOTE | [iOS] xcodebuild: warning: Skipping code signing because the target does not have an Info.plist file and one is not being generated automatically. (in target 'App' from project 'App')
- NOTE | [iOS] xcodebuild: note: Execution policy exception registration failed and was skipped: Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted" (in target 'AaronSwift' from project 'Pods')
- NOTE | [iOS] xcodebuild: note: Execution policy exception registration failed and was skipped: Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted" (in target 'Pods-App' from project 'Pods')
- NOTE | [iOS] xcodebuild: note: Execution policy exception registration failed and was skipped: Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted" (in target 'App' from project 'App')
Analyzed 1 podspec.
AaronSwift.podspec passed validation.
九、配置文件说明
刚才说的检测配置文件是否配置正确，是哪个文件呢？就是工程跟目录下的后缀为podspec的文件，在我的例子中就是AaronSwift.podspec文件。
打开这个文件，里面是工程的配置。我们在用pod命令安装库时，就是找到这个文件，获取地址下载库，并根据配置下载好依赖库和其它工程的配置。
Pod::Spec.new do |s|
s.name = 'AaronSwift'
s.version = '0.1.0'
s.summary = 'Aaron私有Swift公共组件库AaronSwift.'
# 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!
s.description = <<-DESC
TODO: Add long description of the pod here.
DESC
s.homepage = 'https://github.com/AaronYin0514/AaronSwift'
# s.screenshots = 'www.example.com/screenshots_1', 'www.example.com/screenshots_2'
s.license = { :type => 'MIT', :file => 'LICENSE' }
s.author = { 'AaronYin0514' => '562540603@qq.com' }
s.source = { :git => 'https://github.com/AaronYin0514/AaronSwift.git', :tag => s.version.to_s }
# s.social_media_url = 'https://twitter.com/<TWITTER_USERNAME>'
s.ios.deployment_target = '8.0'
s.source_files = 'AaronSwift/Classes/**/*'
# s.resource_bundles = {
# 'AaronSwift' => ['AaronSwift/Assets/*.png']
# }
# s.public_header_files = 'Pod/Classes/**/*.h'
# s.frameworks = 'UIKit', 'MapKit'
# s.dependency 'AFNetworking', '~> 2.3'
end
- s.name ：pod search 搜索的关键词,注意这里一定要和.podspec的名称一样
- s.version ：版本号，这个版本号必须与对应的Tag一致。上面例子中我们设置的为0.1.0
- s.summary : 简介，这个简介你需要修改一下，对项目的简短介绍，不修改的话会有警告。
- s.homepage : 项目主页地址，这个地址需要是https地址
- s.license : 许可证
- s.author : 作者
- s.social_media_url : 社交网址
- s.source : 项目的地址
- s.source_files : 需要包含的源文件，“” 表示匹配所有文件，“*” 表示匹配所有子目录。
- s.resources: 资源文件
- s.requires_arc : 是否支持ARC
- s.dependency ：依赖库
- s.ios.deployment_target = '8.0' : 支持的pod最低版本
十、发布版本
pod repo add AaronSwift https://github.com/AaronYin0514/AaronSwift.git
pod repo push AaronSwift AaronSwift.podspec --allow-warnings
执行这两步操作，操作过程如下
yinzhongzhengdeMacBook-Pro:AaronSwift yinzhongzheng$ pod repo add AaronSwift https://github.com/AaronYin0514/AaronSwift.git
Cloning spec repo `AaronSwift` from `https://github.com/AaronYin0514/AaronSwift.git`
yinzhongzhengdeMacBook-Pro:AaronSwift yinzhongzheng$ pod repo push AaronSwift AaronSwift.podspec --allow-warnings
Validating spec
-> AaronSwift (0.1.0)
- WARN | [iOS] swift: The validator used Swift `4.0` by default because no Swift version was specified. To specify a Swift version during validation, add the `swift_versions` attribute in your podspec. Note that usage of a `.swift-version` file is now deprecated.
- NOTE | xcodebuild: note: Using new build system
- NOTE | [iOS] xcodebuild: note: Planning build
- NOTE | [iOS] xcodebuild: note: Constructing build description
- NOTE | [iOS] xcodebuild: warning: Skipping code signing because the target does not have an Info.plist file and one is not being generated automatically. (in target 'App' from project 'App')
- NOTE | [iOS] xcodebuild: note: Execution policy exception registration failed and was skipped: Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted" (in target 'AaronSwift' from project 'Pods')
- NOTE | [iOS] xcodebuild: note: Execution policy exception registration failed and was skipped: Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted" (in target 'Pods-App' from project 'Pods')
- NOTE | [iOS] xcodebuild: note: Execution policy exception registration failed and was skipped: Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted" (in target 'App' from project 'App')

十一、解释pod repo add 库名称 库地址
这一个操作是将原创仓库添加到本地，执行下面命令：
cd ~/.cocoapods/repos/
open .
就能看到Cocopods的所有本地仓库列表了，例子的库是AaronSwift。我们也可以浏览一下其它的目录，就能找到很多后缀为podspec的文件。
pod install命令就是根据要安装的库的名字在这些目录中遍历，找到对应的配置文件后，解析里面的地址和配置进行下载。
Pod update命令是从远程库，把这些配置文件下载到本地的这个目录中，再install。
十二、解释pod repo push 库名 库配置文件(后缀为podspec) --allow-warnings
这个命令就是发布版本的命令，将版本push到远程，我们在~/.cocoapods/repos/AaronSwift/AaronSwift/目录中，可以找到对应版本号的目录，目录里面就是配置文件（后缀为podspec）。
pod install时指定版本或最新版本时，就是根据版本号找到对应的配置文件的。
十三、pod udpate
进入Example，这个目录中是我们测试代码的工程，pod update后，就安装了我们发布的版本，到此，整个过程就完成了。
yinzhongzhengdeMacBook-Pro:AaronSwift yinzhongzheng$ cd Example/
yinzhongzhengdeMacBook-Pro:Example yinzhongzheng$ ls
