打开 终端
1. 移除系统自带的 因为该rub已经被和谐了 使用ruby.taobao.org
MCJ:~ MCJ$ sudo gem sources -l
*** CURRENT SOURCES ***
https://rubygems.org/
MCJ:~ MCJ$ sudo gem sources --remove https://rubygems.org/
https://rubygems.org/ removed from sources
MCJ:~ MCJ$ sudo gem sources -a https://ruby.taobao.org/
https://ruby.taobao.org/ added to sources
2. 安装 cocoapods（接着刚才的写 sudo gem install cocoapods 系统会自动帮你下载cocoapods）
MCJ:~ MCJ$ sudo gem install cocoapods

3. 在我们项目文件的主文件路径创建一个Podfile文件
MCJ:~ MCJ$ cd /Users/qianfeng/Desktop/Test/CocoaPodsDemo
MCJ:CocoaPodsDemo MCJ$ touch Podfile
4. 打开我们创建的Podfile 文件写入我们想下载的第三库的名称和版本
5. 执行下载第三方库（这个需要一定时间 需要看网速）
MCJ:CocoaPodsDemo MCJ$ pod install --verbose --no-repo-update
Updating local specs repositories
Analyzing dependencies
Downloading dependencies
Using AFNetworking (2.6.3)
Using Reachability (3.0.0)
Using SBJson (4.0.2)
Generating Pods project
Integrating client project
Sending stats
Pod installation complete! There are 3 dependencies from the Podfile and 3 total
pods installed.
这样就是下载成功 如果你想看看你Podfile文件的内容可以使用
MCJ:CocoaPodsDemo MCJ$ cat Podfile
pod 'Reachability', '~> 3.0.0'
pod 'SBJson', '~> 4.0.0'
pod 'AFNetworking', '~> 2.0'
6. 下载成功之后来到项目的文件 以后直接双击CocoaPodsDemo.xcworkspace 打开项目就可以编写的代码
打开项目的效果
7. 在项目里想使用哪个第三方直接导入头文件就行了
8. 如果想在cocoapods 添加新的第三方库
如果知道名字和版本只需要把 名称和版本添加到Podfile文件更新一下pod 就行了
MCJ:CocoaPodsDemo MCJ$ pod install
如果不知道 可以搜索 把搜索到得添加到Podfile文件 更新一下pod 就行了
MCJ:CocoaPodsDemo MCJ$ pod search SDWebimage
