1.在github上面創建自己項目

B8DE34D6-6F9A-45DD-ADA1-85628A6F02EB.jpeg

2.將項目clone到本地

1、$ git init 

2、$ git clone https://github.com/markStudy/BDHelper.git 

2107957-fb8e738ea869368d.jpeg

3. 給倉庫創建個podspec文件

pod spec create **** 

4.編寫podspec文件

2107957-0873736c148d90fd.jpeg

s.source_files = ' ' 的多種寫法

   s.source_files = "BDHelper", "BDHelper/**/*.{h,m}"

表示BDHelper/BDHelper/目錄下的所有 .h 和 .m 文件

   s.source_files = 'BDHelper/**/*

表示BDHelper/ 目錄下所有文件，包括子目錄下所有文件。 **/*表示遞歸

當有多個文件時，應用,隔開

s.source_file = 'MMDrawerController/MMDrawerController.{h,m}', 'MMDrawerController/UIViewController+MMDrawerController*'

5.更新內容到git上面

6.檢查podspec文件

$ pod spec lint ***.podspec

pod lib lint 和 pod spec lint 命令的區別

pod lib lint是只從本地驗證你的pod能否通過驗證
pod spec lint是從本地和遠程驗證你的pod能否通過驗證
我一般都是直接使用pod spec lint去驗證pod有沒有問題

驗證可能出現的錯誤，把我遇到的一些問題, 單獨寫了出來.

• swift版本未指定

  Mark-Mac:BDHelper Mark_Mac$ pod lib lint LZTool.podspec

 -> BDHelper (0.0.3)
[!] The validator for Swift projects uses Swift 3.0 by default, if you are using a different version of swift you can use a `.swift-version` file to set the version for your Pod. For example to use Swift 2.3, run: 
    `echo "2.3" > .swift-version`.

解決方案：echo 3.0 > .swift-version

• fatal: Remote branch 0.0.1 not found in upstream origin

Mark-Mac:BDHelper Mark_Mac$ pod spec lint

這是因為在你托管代碼的庫里(這里是指github)找不到這個分支, 也就是在編輯 BDHelper.podspec時, 里面的字段s.verson, s.source 中的 tag與github創建的release版本號不一致導致, 修改為一樣即可!

• 如果私有庫添加了靜態庫或者dependency用了靜態庫

找了一些相關的，這個錯誤是因為依賴庫（s.dependency）包含了.a靜態庫造成的。雖然這并不影響Pod的使用，但是驗證是無法通過的。可以通過 --use-libraries 來讓驗證通過。使用以下的命令:

pod spec lint ****.podspec --use-libraries

• 如果還有警告，輸入--allow-warnings

$ pod spec lint ****.podspec --use-libraries --allow-warnings

7.發布自己的pods到CocoaPods trunk

使用CocoaPods trunk之前請確認CocoaPods版本是否是0.33或以上，打開Teaminal(終端)輸入pod --version即可查看，如果版本過低，請執行sudo gem install cocoapods安裝最新版本！

• 注冊trunk

pod trunk register 郵箱地址 '用戶名' --description='用戶名'  --verbose

如果所有的步驟都能成功的話，你會受到一份郵件，需要點擊驗證下。

• 查看trunk

pod trunk me

可以查看你已經注冊的信息，其中包含你的name、email、since、Pods、sessions，其中Pods為你往CocoaPods提交的所有的Pod！

• 添加其他維護者（如果你的pod是由多人維護的，你也可以添加其他維護者）

pod trunk add-owner '用戶名' 郵箱地址

• 將你的庫文件.podspec文件提交到公有的specs上面,成功后會出現Congrats信息噢~

$ pod trunk push 

• 如果還有警告，輸入--allow-warnings

$ pod trunk push --allow-warnings

8.Done

執行pod install 命令

補充

這時候輸入 pod search *** ，你會發現可能搜索不到你剛剛上傳的庫
解決方案：刪除~/Library/Caches/CocoaPods目錄下的search_index.json文件

rm ~/Library/Caches/CocoaPods/search_index.json

• 刪除成功后再執行pod search
• 輸出：Creating search index for spec repo 'master'.. Done!，稍等片刻就會出現所有帶***字段的類庫出現。
