怎样修改Pods工程名？

一、查看官方文档，Podfile是否支持设置工程名？

答案：没有相关选项

二、分析源码

1、找到GEM_HOME

echo $GEM_HOME

2、在GEM_HOME下搜索相关代码

ag Pods

3、找到了关键代码

$GEM_HOME/gems/cocoapods-1.5.3/lib/cocoapods/sandbox.rb
$GEM_HOME/gems/cocoapods-1.5.3/lib/cocoapods/config.rb

4、找到了关键

$GEM_HOME/gems/cocoapods-1.5.3/lib/cocoapods/sandbox.rb
    def project_path
      root + 'Pods.xcodeproj'
    end

$GEM_HOME/gems/cocoapods-1.5.3/lib/cocoapods/config.rb
    def sandbox_root
      @sandbox_root ||= installation_root + 'Pods'
    end

三、利用pre_install编写代码

在Podfile里添加pre_install

pre_install do |installer|
    original_sand = installer.sandbox
    def original_sand.project_path
        return @root + 'BarPods.xcodeproj'
    end
    puts installer.sandbox.project_path
end

四、测试

执行 pod install 成功修改了工程名
