# platform :ios, '9.0'use_frameworks!

pod 'Alamofire', ‘3.0’

pod 'SDWebImage'

target 'httpsTest' do

  # Comment this line if you're not using Swift and don't want to use dynamic frameworks

  use_frameworks!

  # Pods for httpsTest

  target 'httpsTestTests' do

    inherit! :search_paths

    # Pods for testing

  end

end

四、下载第三方
