前言

經(jīng)常使用別人的封裝庫或者項(xiàng)目，在項(xiàng)目開發(fā)中自己也有封裝，即使不能給別人廣泛使用，也可以自己在多項(xiàng)目中pod方式使用自己封裝的代碼
前提：mac上已經(jīng)裝好了pod,git

一、創(chuàng)建自己庫添加Cocoapods支持

1、基于pod自動創(chuàng)建項(xiàng)目

在終端輸入

pod lib create JGCache

提示對應(yīng)的詢問命令

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

項(xiàng)目創(chuàng)建成功，并編譯成功

2、接下來在https://github.com/官網(wǎng)自己的賬號下創(chuàng)建一個倉庫JGCache（這里不是重點(diǎn)，不用介紹了）

3、將pod命令自動創(chuàng)建的項(xiàng)目上傳到github JGCache項(xiàng)目中，（這里不是重點(diǎn)，不用介紹了）

4、給倉庫JGCache 主分支master 創(chuàng)建一個tag 0.1.0 （這里不是重點(diǎn)，不用介紹了）

5、打開項(xiàng)目中的JGCache.podspec文件可以看到默認(rèn)設(shè)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/lbj147123@163.com/JGCache'
  # s.screenshots     = 'www.example.com/screenshots_1', 'www.example.com/screenshots_2'
  s.license          = { :type => 'MIT', :file => 'LICENSE' }
  s.author           = { 'lbj147123@163.com' => 'lbj147123@163.com' }
  s.source           = { :git => 'https://github.com/lbj147123@163.com/JGCache.git', :tag => s.version.to_s }
  # s.social_media_url = 'https://twitter.com/<TWITTER_USERNAME>'

  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、修改項(xiàng)目中的JGCache.podspec文件的設(shè)置為（這里就不介紹每一項(xiàng)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' => 'lbj147123@163.com' }
  s.source           = { :git => 'https://github.com/Ucself/JGCache.git', :tag => s.version.to_s }
  # s.social_media_url = 'https://twitter.com/<TWITTER_USERNAME>'

  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、檢測填寫的podspec是否有錯誤，cd進(jìn)入JGCache文件目錄

pod spec lint

8、測試本地導(dǎo)入的文件是否報(bào)錯。cd 進(jìn)入項(xiàng)目Example文件路徑,導(dǎo)入依賴的第三方庫

pod install 

9、上傳的cocopods管理

pod trunk push JGCache.podspec --allow-warnings

二、更新自己庫添加Cocoapods支持

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

2、在啊gitbug對你的工程添加標(biāo)簽如1.0.0

3、上傳工程工程代碼

4、再次執(zhí)行

pod trunk push JGCache.podspec --allow-warnings
