安装方式异常简单 , Mac 下都自带 ruby，使用 ruby 的 gem 命令即可下载安装：

$ sudo gem install cocoapods $ pod setup 

如果你的 gem 太老，可能也会有问题，可以尝试用如下命令升级 gem:

sudo gem update --system 

另外，ruby 的软件源 https://rubygems.org 因为使用的是亚马逊的云服务，所以被墙了，需要更新一下 ruby 的源，使用如下代码将官方的 ruby 源替换成国内淘宝的源：

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

还有一点需要注意，pod setup在执行时，会输出Setting up CocoaPods master repo，但是会等待比较久的时间。这步其实是 Cocoapods 在将它的信息下载到 ~/.cocoapods目录下，如果你等太久，可以试着 cd 到那个目录，用du -sh *来查看下载进度。你也可以参考本文接下来的使用 cocoapods 的镜像索引一节的内容来提高下载速度。

//////新建工程 CocoaPods

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

编辑文件

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 设置这个了 就可以直接索引出了
cocoapods 无法引入头文件的问题
选择工程的 Target -> Build Settings 菜单，找到\”User Header Search Paths\”设置项
新增一个值"$(PODS_ROOT)"，并且选择\”recursive\”，这样xcode就会在项目目录中递归搜索文件

使用 CocoaPods 的镜像索引

所有的项目的 Podspec 文件都托管在https://github.com/CocoaPods/Specs。第一次执行pod setup时，CocoaPods 会将这些podspec索引文件更新到本地的 ~/.cocoapods/目录下，这个索引文件比较大，有 80M 左右。所以第一次更新时非常慢，笔者就更新了将近 1 个小时才完成。

一个叫 akinliu 的朋友在 gitcafe 和 oschina 上建立了 CocoaPods 索引库的镜像，因为 gitcafe 和 oschina 都是国内的服务器，所以在执行索引更新操作时，会快很多。如下操作可以将 CocoaPods 设置成使用 gitcafe 镜像：

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

将以上代码中的 https://gitcafe.com/akuandev/Specs.git 替换成 http://git.oschina.net/akuandev/Specs.git 即可使用 oschina 上的镜像。
