1、请在命令行输入 

pod search tgrefreshswift

2、弹出下面提示说明可以使用

3、在你的podfile中导入tgrefreshswift

即这一句

pod 'TGRefreshSwift'

# Uncomment the next line to define a global platform for your project# platform :ios, '9.0'target 'TGRefreshSwiftDemo' do  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks  use_frameworks!  # Pods for TGRefreshSwiftDemopod 'TGRefreshSwift'end

过程图

4、使用控件
