讓你的項(xiàng)目支持Cocoa Pods，作為第三方庫(kù)方便的被別人使用：

本案前提
  你已經(jīng)有一個(gè)項(xiàng)目，并且上傳到了gitbug上
  項(xiàng)目含有l(wèi)iecnce文件（沒(méi)有的話，后面校驗(yàn)不會(huì)通過(guò)）

準(zhǔn)備工作一：注冊(cè)trunk

pod trunk register EMAIL [NAME]

Examples:
$ pod trunk register eloy@example.com `Eloy Durán` --description=`Personal Laptop`
$ pod trunk register eloy@example.com --description=`Work Laptop`
$ pod trunk register eloy@example.com

然后會(huì)收到郵件，點(diǎn)擊郵件鏈接確認(rèn)

準(zhǔn)備工作二：為你的項(xiàng)目添加PodSpec
  在當(dāng)前工作目錄中創(chuàng)建一個(gè)名為NAME.podspec的PodSpec
  pod spec create [NAME|https://github.com/USER/REPO]

編輯本地生成的NAME.podspec文件 

一個(gè)簡(jiǎn)單的例子：
Pod::Spec.new do |spec|
  spec.name             = 'Reachability'
  spec.version          = '3.1.0'
  spec.license          = { :type => 'BSD' }
  spec.homepage         = 'https://github.com/tonymillion/Reachability'
  spec.authors          = { 'Tony Million' => 'tonymillion@gmail.com' }
  spec.summary          = 'ARC and GCD Compatible Reachability Class for iOS and macOS.'
  spec.source           = { :git => 'https://github.com/tonymillion/Reachability.git', :tag => 'v3.1.0' }
  spec.source_files     = 'Reachability.h,m'
  spec.framework        = 'SystemConfiguration'
  spec.requires_arc     = true
end

校驗(yàn)：
pod spec lint [NAME.podspec|DIRECTORY|http://PATH/NAME.podspec ...]
或 pod lib lint 
或 pod spec lint --allow-warnings --verbose NAME.podspec 顯示錯(cuò)誤信息和警告
如果有錯(cuò)誤就根據(jù)提示修改NAME.podspec


確認(rèn)無(wú)誤，提交code到git倉(cāng)庫(kù)中，并打上tag版本號(hào)

創(chuàng)建Spec Repo
pod repo add NAME URL [BRANCH]
如：
pod repo add NAME http://PATH/NAME.podspec

遠(yuǎn)程代碼被拷貝在本地，在 ~/.cocoapods/repos/. 中可以查看
這樣我們?cè)谝惶靏ithub上的項(xiàng)目就被指定為Cocoa pods中名為NAME的項(xiàng)目

向Spec Repo提交podspec

#前面是本地Repo名字 后面是podspec名字
pod repo push REPO_NAME SPEC_NAME.podspec
如：
pod repo push myPods somePods.podspec

在項(xiàng)目中使用CocoaPods

touch Podfile

source 'https://github.com/CocoaPods/Specs.git'
source 'https://github.com/Artsy/Specs.git'

platform :ios, '9.0'
inhibit_all_warnings!

target 'MyApp' do
  pod 'GoogleAnalytics', '~> 3.1'

  # Has its own copy of OCMock
  # and has access to GoogleAnalytics via the app
  # that hosts the test target

  target 'MyAppTests' do
    inherit! :search_paths
    pod 'OCMock', '~> 2.0.1'
  end
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    puts target.name
  end
end
