# CocoaPods
#
# We recommend against adding the Pods directory to your .gitignore. However
# you should judge for yourself, the pros and cons are mentioned at:

# It is recommended to not store the screenshots in the git repo. Instead, use fastlane to re-generate the 
# screenshots whenever they are needed.

关于 .DS_Store 文件

DS_Store 是用来存储这个文件夹的显示属性的，比如文件图标的摆放位置。删除以后的副作用就是这些信息的失去。如果对这些文件进行版本控制追踪的话，每一个人的操作系统都不同，这个文件的信息都是变化的，所以每次都会发生修改，而且这些文件本身也没有追踪的必要。

删除所有的 .DS_Store 文件

sudo find / -name ".DS_Store" -depth -exec rm {} \;

禁止 .DS_store 生成，重启系统生效

defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool TRUE

恢复 .DS_store 生成

defaults delete com.apple.desktopservices DSDontWriteNetworkStores

可以通过配置，全局忽略 .DS_Store 文件

1.创建 ~/.gitignore_global 文件

# .gitignore_global
.DS_Store

2.git config --global core.excludesfile '~/.gitignore_global'
