1. 安装git；

2. 安装cocoapods；

3. 在电脑用户的根目录下创建仓库名：repos.local.git，实际上的路径就是：/Users/master/repos.local.git；

4. 在终端中，进入刚才创建的仓库名文件夹cd /Users/master/repos.local.git；

5. 将此文件夹进行git初始化git init；

6. 将自己创建的框架工程复制进来

7.在终端进入UIImageExtension文件夹下，cd /Users/master/repos.local.git/UIKit/UIImageExtension；

8. 提交framework：git add . && git commit -m "Add UIImage Extension Tools 2017.11.19"

9. 创建podspec文件，UIImageExtension.podspec，pod spec create UIImageExtension

10. 使用Xcode打开UIImageExtension.podspec，进行编辑

#
#  Be sure to run `pod spec lint UIImageExtension.podspec' to ensure this is a
#  valid spec and to remove all comments including this before submitting the spec.
#
#  To learn more about Podspec attributes see http://docs.cocoapods.org/specification.html
#  To see working Podspecs in the CocoaPods repo see https://github.com/CocoaPods/Specs/

  # ―――  Spec Metadata  ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  These will help people to find your library, and whilst it
  #  can feel like a chore to fill in it's definitely to your advantage. The
  #  summary should be tweet-length, and the description more in depth.
  #

  s.name         = "UIImageExtension"
  s.version      = "0.0.1"
  s.summary      = "A short description of UIImageExtension."

  # This description is used to generate tags and improve search results.
  #   * Think: What does it do? Why did you write it? What is the focus?
  #   * Try to keep it short, snappy and to the point.
  #   * Write the description between the DESC delimiters below.
  #   * Finally, don't worry about the indent, CocoaPods strips it!
  s.description  = <<-DESC
                    It is a UIImage Extension used on iOS, which implement by Objective-C.
                    DESC

  s.homepage     = "http://www.jianshu.com/u/c191b24afeae"
  # s.screenshots  = "www.example.com/screenshots_1.gif", "www.example.com/screenshots_2.gif"


  # ―――  Spec License  ――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  Licensing your code is important. See http://choosealicense.com for more info.
  #  CocoaPods will detect a license file if there is a named LICENSE*
  #  Popular ones are 'MIT', 'BSD' and 'Apache License, Version 2.0'.
  #

  s.license      = "MIT"
  # s.license      = { :type => "MIT", :file => "FILE_LICENSE" }


  # ――― Author Metadata  ――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  Specify the authors of the library, with email addresses. Email addresses
  #  of the authors are extracted from the SCM log. E.g. $ git log. CocoaPods also
  #  accepts just a name if you'd rather not provide an email address.
  #
  #  Specify a social_media_url where others can refer to, for example a twitter
  #  profile URL.
  #

  s.author             = { "UIImageExtension" => "http://www.jianshu.com/u/c191b24afeae" }
  # Or just: s.author    = ""
  # s.authors            = { "" => "" }
  # s.social_media_url   = "http://twitter.com/"

  # ――― Platform Specifics ――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  If this Pod runs only on iOS or OS X, then specify the platform and
  #  the deployment target. You can optionally include the target after the platform.
  #

  # s.platform     = :ios
  s.platform     = :ios, "7.0"

  #  When using multiple platforms
  # s.ios.deployment_target = "5.0"
  # s.osx.deployment_target = "10.7"
  # s.watchos.deployment_target = "2.0"
  # s.tvos.deployment_target = "9.0"


  # ――― Source Location ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  Specify the location from where the source should be retrieved.
  #  Supports git, hg, bzr, svn and HTTP.
  #

  s.source       = { :git => "/Users/master/repos.local.git/UIKit/UIImageExtension/UIImageExtension", :tag => "#{s.version}" }


  # ――― Source Code ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  CocoaPods is smart about how it includes source code. For source files
  #  giving a folder will include any swift, h, m, mm, c & cpp files.
  #  For header files it will include any header in the folder.
  #  Not including the public_header_files will make all headers public.
  #

  s.source_files  = "UIImageExtension", "UIImageExtension/**/*.{h,m}"
  s.exclude_files = "Classes/Exclude"

  s.public_header_files = "UIImageExtension/**/*.h"


  # ――― Resources ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  A list of resources included with the Pod. These are copied into the
  #  target bundle with a build phase script. Anything else will be cleaned.
  #  You can preserve files from being cleaned, please don't preserve
  #  non-essential files like tests, examples and documentation.
  #

  # s.resource  = "icon.png"
  # s.resources = "Resources/*.png"

  # s.preserve_paths = "UIImageExtension", "UIImageExtension/UIImageExtension"


  # ――― Project Linking ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  Link your library with frameworks, or libraries. Libraries do not include
  #  the lib prefix of their name.
  #

  # s.framework  = "UIImageExtension"
  # s.frameworks = "SomeFramework", "AnotherFramework"

  s.library   = "UIImageExtension"
  # s.libraries = "iconv", "xml2"


  # ――― Project Settings ――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
  #
  #  If your library depends on compiler flags you can set them in the xcconfig hash
  #  where they will only apply to your library. If you depend on other Podspecs
  #  you can include multiple dependencies to ensure it works.

  s.requires_arc = true

  s.xcconfig = { "HEADER_SEARCH_PATHS" => "/Users/master/repos.local.git/UIKit/UIImageExtension/UIImageExtension" }
  # s.dependency "JSONKit", "~> 1.4"

end

11. 在终端中cd到需要用到UIImageExtension的工程项目目录，创建Podfile文件，配置Podfile文件：pod 'UIImageExtension', :path => '/Users/master/repos.local.git/UIKit/UIImageExtension'

12. 在需要用到的地方引用头文件就OK了。
