iOS框架如何发布到CocoaPods

前言

经常使用别人的封装库或者项目，在项目开发中自己也有封装，即使不能给别人广泛使用，也可以自己在多项目中pod方式使用自己封装的代码
前提：mac上已经装好了pod,git

一、创建自己库添加Cocoapods支持

1、基于pod自动创建项目

在终端输入

pod lib create JGCache

提示对应的询问命令

Cloning `https://github.com/CocoaPods/pod-template.git` into `JGCache`.
Configuring JGCache template.

------------------------------

To get you started we need to ask a few questions, this should only take a minute.

If this is your first time we recommend running through with the guide: 
 - http://guides.cocoapods.org/making/using-pod-lib-create.html
 ( hold cmd and double click links to open in a browser. )


What language do you want to use?? [ Swift / ObjC ]
 > Swift

Would you like to include a demo application with your library? [ Yes / No ]
 > Yes

Which testing frameworks will you use? [ Quick / None ]
 > None

Would you like to do view based testing? [ Yes / No ]
 > No

项目创建成功，并编译成功

2、接下来在https://github.com/官网自己的账号下创建一个仓库JGCache（这里不是重点，不用介绍了）

3、将pod命令自动创建的项目上传到github JGCache项目中，（这里不是重点，不用介绍了）

4、给仓库JGCache 主分支master 创建一个tag 0.1.0 （这里不是重点，不用介绍了）

5、打开项目中的JGCache.podspec文件可以看到默认设置

#
# Be sure to run `pod lib lint JGCache.podspec' to ensure this is a
# valid spec before submitting.
#
# Any lines starting with a # are optional, but their use is encouraged
# To learn more about a Podspec see http://guides.cocoapods.org/syntax/podspec.html
#

Pod::Spec.new do |s|
  s.name             = 'JGCache'
  s.version          = '0.1.0'
  s.summary          = 'A short description of JGCache.'

# 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
TODO: Add long description of the pod here.
                       DESC

  s.homepage         = 'https://github.com/[email protected]/JGCache'
  # s.screenshots     = 'www.example.com/screenshots_1', 'www.example.com/screenshots_2'
  s.license          = { :type => 'MIT', :file => 'LICENSE' }
  s.author           = { '[email protected]' => '[email protected]' }
  s.source           = { :git => 'https://github.com/[email protected]/JGCache.git', :tag => s.version.to_s }
  # s.social_media_url = 'https://twitter.com/'

  s.ios.deployment_target = '8.0'

  s.source_files = 'JGCache/Classes/**/*'
  
  # s.resource_bundles = {
  #   'JGCache' => ['JGCache/Assets/*.png']
  # }

  # s.public_header_files = 'Pod/Classes/**/*.h'
  # s.frameworks = 'UIKit', 'MapKit'
  # s.dependency 'AFNetworking', '~> 2.3'
end

6、修改项目中的JGCache.podspec文件的设置为（这里就不介绍每一项的意思了）

Pod::Spec.new do |s|
  s.name             = 'JGCache'
  s.version          = '0.1.0'
  s.summary          = 'this is description'

# 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
TODO: this is description
                       DESC

  s.homepage         = 'https://github.com/Ucself/JGCache'
  # s.screenshots     = 'www.example.com/screenshots_1', 'www.example.com/screenshots_2'
  s.license          = { :type => 'MIT', :file => 'LICENSE' }
  s.author           = { '李保君' => '[email protected]' }
  s.source           = { :git => 'https://github.com/Ucself/JGCache.git', :tag => s.version.to_s }
  # s.social_media_url = 'https://twitter.com/'

  s.ios.deployment_target = '8.0'

  s.source_files = 'JGCache/Classes/**/*'
  
  # s.resource_bundles = {
  #   'JGCache' => ['JGCache/Assets/*.png']
  # }

  # s.public_header_files = 'Pod/Classes/**/*.h'
  # s.frameworks = 'UIKit', 'MapKit'
  s.dependency 'ObjectMapper', '~> 3.0.0'
end

7、检测填写的podspec是否有错误，cd进入JGCache文件目录

pod spec lint

8、测试本地导入的文件是否报错。cd 进入项目Example文件路径,导入依赖的第三方库

pod install 

9、上传的cocopods管理

pod trunk push JGCache.podspec --allow-warnings

二、更新自己库添加Cocoapods支持

1、JGCache.podspec 文件中你需要更改的项目更改（主要更改版本如：1.0.0）

2、在啊gitbug对你的工程添加标签如1.0.0

3、上传工程工程代码

4、再次执行

pod trunk push JGCache.podspec --allow-warnings
