安裝方式異常簡單 , Mac 下都自帶 ruby，使用 ruby 的 gem 命令即可下載安裝：

$ sudo gem install cocoapods $ pod setup 

如果你的 gem 太老，可能也會有問題，可以嘗試用如下命令升級 gem:

sudo gem update --system 

另外，ruby 的軟件源 https://rubygems.org 因為使用的是亞馬遜的云服務，所以被墻了，需要更新一下 ruby 的源，使用如下代碼將官方的 ruby 源替換成國內淘寶的源：

gem sources --remove https://rubygems.org/ gem sources -a https://ruby.taobao.org/ gem sources -l 

還有一點需要注意，pod setup在執行時，會輸出Setting up CocoaPods master repo，但是會等待比較久的時間。這步其實是 Cocoapods 在將它的信息下載到 ~/.cocoapods目錄下，如果你等太久，可以試著 cd 到那個目錄，用du -sh *來查看下載進度。你也可以參考本文接下來的使用 cocoapods 的鏡像索引一節的內容來提高下載速度。

//////新建工程 CocoaPods

suchao:Desktop dllo$ cd CocoaPods
suchao:CocoaPods dllo$ ls
suchao:CocoaPods dllo$ pod init //創建podfile文件
suchao:CocoaPods dllo$ pod install

編輯文件

platform :ios
pod 'RegexKitLite-NoWarning', '~> 1.1.0'

platform :ios, '7.0'
pod "AFNetworking", "~> 2.0”

suchao:CocoaPods dllo$ pod install

//////////////////////////

生敲也可以 設置這個了 就可以直接索引出了
cocoapods 無法引入頭文件的問題
選擇工程的 Target -> Build Settings 菜單，找到\”User Header Search Paths\”設置項
新增一個值"$(PODS_ROOT)"，并且選擇\”recursive\”，這樣xcode就會在項目目錄中遞歸搜索文件

使用 CocoaPods 的鏡像索引

所有的項目的 Podspec 文件都托管在https://github.com/CocoaPods/Specs。第一次執行pod setup時，CocoaPods 會將這些podspec索引文件更新到本地的 ~/.cocoapods/目錄下，這個索引文件比較大，有 80M 左右。所以第一次更新時非常慢，筆者就更新了將近 1 個小時才完成。

一個叫 akinliu 的朋友在 gitcafe 和 oschina 上建立了 CocoaPods 索引庫的鏡像，因為 gitcafe 和 oschina 都是國內的服務器，所以在執行索引更新操作時，會快很多。如下操作可以將 CocoaPods 設置成使用 gitcafe 鏡像：

pod repo remove master pod repo add master https://gitcafe.com/akuandev/Specs.git pod repo update 

將以上代碼中的 https://gitcafe.com/akuandev/Specs.git 替換成 http://git.oschina.net/akuandev/Specs.git 即可使用 oschina 上的鏡像。
