注意

1、https://github.com/ZipArchive/ZipArchive  GitHub上是这个名字，但是导入时pod install SSZipArchive

2、可以配合网络框架Alamofire等一起用，加ATS

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'ziptest' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for ziptest
pod 'Alamofire'
pod 'SSZipArchive'
end
