1 Cocoapods简介
CocoaPods is a dependency manager for Swift and Objective-C Cocoa projects. It has over eighteen thousand libraries and can help you scale your projects elegantly.
2 安装Cocoapods
CocoaPods is built with Ruby and is installable with the default Ruby available on OS X.
2.1 替换Ruby源
ruby默认引用的Amazon S3的资源文件, 由于国内网络原因(你懂的), 所以将ruby源修改为淘宝的RubyGems 镜像.
$ gem sources --add https://ruby.taobao.org/ --remove https://rubygems.org/ $ gem sources -l
2.2 安装cocoapods
sudo gem install cocoapods
pod setup
成功后就可以用pod install安装cocoapods库.
