8.修改源

	git -C "$(brew --repo)" remote set-url origin 'https://github.com/Homebrew/brew.git'
git -C "$(brew --repo homebrew/core)" remote set-url origin 'https://github.com/Homebrew/homebrew-core.git'
git -C "$(brew --repo homebrew/cask)" remote set-url origin 'https://github.com/Homebrew/homebrew-cask.git'

brew update


安装软件：brew install xxx

卸载软件: brew uninstall xxx

搜索软件:brew search xxx

查看列表:brew list

更新brew:brew update

清理所有包的旧版本:brew cleanup

清理指定包的旧版本：brew cleanup $formula

查看可清理的旧版本包 brew cleanup -n

$ echo 'export PATH="/usr/local/opt/openssl@3.0/bin:$PATH"' >> ~/.zshrc
$ source ~/.zshrc

If you need to have openssl@3 first in your PATH, run:
  echo 'export PATH="/usr/local/opt/openssl@3/bin:$PATH"' >> ~/.zshrc

For compilers to find openssl@3 you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl@3/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl@3/include"

brew link --overwrite openssl@1.1

> #### 四、使用cocoaPods

* 进入工程目录 ``` cd ~/DeskTop/TestProject  ``` 
* 建立Podfile:  ``` touch Podfile ``` (必须Podfile)
* 搜索三方库：``` pod search AFNetworking ``` (复制内容 ‘AFNetworking’， ‘~>2.5.3’)
* 打开Podfile:  ``` open -e Podfile ``` 并粘贴复制的内容
* Podfile格式如下
	
	```
	# 私有
	source 'http://git.idengyun.com/iOSTeam/KNSpec.git'
	# 三方	
	source 'https://github.com/CocoaPods/Specs.git'
	
	platform :ios, '8.0'
	
	inhibit_all_warnings!
	
	# 如果@import Charts; 方式导入可以不用use_frameworks!生成库文件
	# use_frameworks!
	
	# 每个工程使用自己的cocopods版本
	# gem 'cocoapods', '1.7.5'
	
	xcodeproj 'TestProject.xcodeproj'
	
	target 'Target1' do
	    
	    pod 'DDYQRCode', '~> 1.1.1'
	end
	
	target 'Target2' do
	    
	    pod 'DDYCamera', '~> 1.1.1'
	end
	
	=begin
	这里写多行注释
	=end
	
	```
	
* 执行 ``` pod install --verbose --no-repo-update ```     
* 需要更新才用此步骤，更新 ``` pod update --verbose --no-repo-update ``` 
* 若新tag没拉取下来就删除缓存 ``` ~/Library/Caches/CocoaPods/Pods/Release ```

> #### 五、让自己的库支持cocoapods管理

* 进入工程目录
* 建立 .podspec 文件 ``` pod spec create DDYQRCode ```
* 填写内容 
	
	```
	Pod::Spec.new do |ddyspec|
	    ddyspec.name         = 'DDYQRCode'
	    ddyspec.version      = '1.1.1'
	    ddyspec.summary      = '二维码/条形码生成'
	    ddyspec.homepage     = 'https://github.com/RainOpen/DDYQRCode'
	    ddyspec.license      = 'MIT'
	    ddyspec.authors      = {'Rain' => '634778311@qq.com'}
	    ddyspec.platform     = :ios, '8.0'
	    ddyspec.source       = {:git => 'https://github.com/RainOpen/DDYQRCode.git', :tag => ddyspec.version}
	    ddyspec.source_files = 'DDYQRCode/DDYQRCode/*.{h,m}'
	    ddyspec.resource     = 'DDYQRCode/DDYQRCode/DDYQRCode.bundle'
	    ddyspec.requires_arc = false
	    # s.framework  = "AVFoundation"
	    # s.frameworks = "UIKit", "AVFoundation"
	    # s.dependency "JSONKit", "~> 1.4"
	end
	```
* 校验格式是否正确 ``` pod spec lint DDYQRCode.podspec --verbose ```
* 注册Trunk ``` pod trunk register 634778311@qq.com 'Rain' --description='iOS' --verbose ```
* 邮箱点击链接验证
* Trunk信息 ``` pod trunk me ```
* 多人维护添加成员 ``` pod trunk add-owner ARAnalytics kyle@cocoapods.org ```
* 发布到pod Trunck ``` pod trunk push DDYQRCode.podspec ```
* 如果必要的话更新pod ``` pod setup ```
* 删除单个版本 ``` pod trunk delete PODNAME VERSION ```
* 删除所有版本 ``` pod trunk deprecate PODNAME ``` (有提示回复y)

> #### 六、卸载指定版本

* 查看cocoapods相关安装 ``` gem list --local | grep cocoapods ```
* 删除相关 ``` sudo gem uninstall cocoapods-deintegrate ```
* 移除指定 ``` sudo gem uninstall cocoapods -v 1.7.5 ```

> #### setup加速

1. ##### gitee镜像
	
	```
	pod repo remove master   
	pod repo add master https://gitee.com/mirrors/CocoaPods-Specs   
	pod repo update   
	```
2. ##### 清华镜像


	```
	pod repo remove master   
	pod repo add master https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git   
	pod repo update   
	```

3. ##### iOS工程如果有Podfile要更改

	```
	source 'https://gitee.com/mirrors/CocoaPods-Specs.git'
	source 'https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git'
	```
