# 如何在已建立的iOS專案忽略git已經紀錄的Pods？
###### tags: `iOS`
## 情況
接到一個舊案子，可能因為這案子的人對git的操作不熟悉，因此可能有使用git，但是沒有加入gitignore，那我們要如何幫舊案加入呢？因為Pods可以直接透過Pod install來安裝，因此希望不要上傳。

## 建立 .gitignore

#### 目標：
在專案資料夾內建立一個.gitignore檔案，並在.gitignore內加入哪些要忽略的檔案，讓git時可以自動忽略

#### 作法：
進入[gitignore.io](https://www.toptal.com/developers/gitignore)
輸入swift然後搜尋，如下圖所示(也可以輸入其他語言)

找到

# Pods/

並把#註解拿掉 (其他也有想忽略的也一併把#拿掉)
可以得到下面的程式碼
然後複製起來，等等會貼到.gitignore檔內

## Obj-C/Swift specific

## App packaging

# Swift Package Manager
# Add this line if you want to avoid checking in source code from Swift Package Manager dependencies.

# Package.pins
# Package.resolved
# *.xcodeproj
# Xcode automatically generates this directory with a .xcworkspacedata file and xcuserdata
# hence it is not needed unless you have added a package configuration file to your project

# 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.

開啟終端機

 cd YourProjectFolder //進入你的資料夾
 vi .gitignore //建立.gitignore檔案

這時候會進入vi編輯器
點擊字母a進入編輯模式
將剛剛的程式碼貼上
完成後輸入:wq <-這是vi的指令，詳情自己查

先進行一次commit

git add .
git commit -m "add gitignore"

這樣就完成加入gitignore

## 移除原本的pod cache

git rm -r --cached . //移除原本的cache
git add .
git commit -m ".gitignore is now working"

這樣子就不會再將Pods資料夾內的檔案上傳了
