iOS 创建pod公有库（初级一）

第一次搞这个，我太难了。

[!] Please verify the session by clicking the link in the verification email that has been sent to YOURMAIL

去邮箱点击验证链接

此时您的邮箱中应该有一封来自 [CocoaPods] Confirm your session. 的邮件，点击邮件中的链接进行验证。

验证是否注册成功

下面内容，表示您已经注册成功。

$ pod trunk me
  - Name:     YOURNAME
  - Email:    YOURMAIL
  - Since:    May 23rd, 2018 03:02
  - Pods:
    - PodName

0x2 创建公有 Pod 库

创建一个Git仓库

创建过程请自行百度，谢谢！！！如果是在搜不到，那就私信我吧！?

假设我们已经成功创建了一个仓库, 关键信息如下：

仓库主页: https://github.com/YOURGITHUBNAME/YOURPODNAME

进入您创建的仓库后，地址栏中的地址

git 地址: https://github.com/YOURGITHUBNAME/YOURPODNAME.git

git地址，点击 Clone or download 按钮，选择 HTTPS 地址，别问为什么，因为 CocoaPods 要求

创建 Pod 库

执行: pod lib create YOURPODNAME，接下来按照提示，根据自己的情况进行就可以了。

$ pod lib create YOURPODNAME
Cloning `https://github.com/CocoaPods/pod-template.git` into `YOURPODNAME`.
Configuring YOURPODNAME 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:

Running pod install on your new library.

Analyzing dependencies
Fetching podspec for `YOURPODNAME` from `../`
Downloading dependencies
Installing YOURPODNAME (0.1.0)
Generating Pods project
Integrating client project

[!] Please close any current Xcode sessions and use `YOURPODNAME.xcworkspace` for this project from now on.
Sending stats
Pod installation complete! There is 1 dependency from the Podfile and 1 total pod installed.

 Ace! you're ready to go!
 We will start you off by opening your project in Xcode
  open 'YOURPODNAME/Example/YOURPODNAME.xcworkspace'

To learn more about the template see `https://github.com/CocoaPods/pod-template.git`.
To learn more about creating a new pod, see `https://guides.cocoapods.org/making/making-a-cocoapod`.

编辑 YOURPODNAME.podspec

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

# 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/YOURGITHUBNAME/YOURPODNAME'
  # s.screenshots     = 'www.example.com/screenshots_1', 'www.example.com/screenshots_2'
  s.license          = { :type => 'MIT', :file => 'LICENSE' }
  s.author           = { 'YOURNAME' => 'YOURMAIL' }
  s.source           = { :git => 'https://github.com/YOURGITHUBNAME/YOURPODNAME.git', :tag => s.version.to_s }
  # s.social_media_url = 'https://twitter.com/'

  s.ios.deployment_target = '8.0'

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

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

必须要修改的:

s.summary: pod 摘要
s.description: pod 描述
s.homepage: pod 在 github 中的地址
s.author: 作者姓名及邮箱
s.source: pod 的 git 地址

其余的根据您的实际情况进行修改，每个字段的描述，下篇文章中会详细介绍！

验证 YOURPODNAME.podspec

$ pod lib lint

 -> YOURPODNAME (0.1.0)
    - WARN  | summary: The summary is not meaningful.
    - WARN  | url: The URL (https://github.com/YOURGITHUBNAME/YOURPODNAME) is not reachable.

[!] YOURPODNAME did not pass validation, due to 2 warnings (but you can use `--allow-warnings` to ignore them).
You can use the `--no-clean` option to inspect any issue.

虽然上面还有两个 WARN，但是已经符合官方的标准了，可以进行提交操作了。但是！如果您是完美主义者，可以彻底处理干净后在进行提交！（我解决了，您随意！）

提交代码

$ git add .
$ git commit -m "创建 pod 库"
$ git push

创建并提交 tag

$ git tag -a 0.1.0 -m '创建 pod 库'
$ git push origin --tags

注意： 此处的 tag 应与 .podspec 文件中的 s.version 保持一致。每次修改 pod 中的代码，添加 tag 后，都应同时修改 .podspec 文件中的 s.version

0x3 提交 pod

$ pod trunk push

恭喜您，您已经成功的将您创建的 pod 库推送到了官方 pod 库！

0x4 坑点 & 解决方案

1. Failed to open TCP connection to trunk.cocoapods.org:443 (getaddrinfo: nodename nor servname provided, or not known)

解： 此问题常见于 pod trunk 相关的命令。网络大环境不行，要么呢啥（技术都懂的），要么连接手机开热点进行操作。

2. Unable to accept duplicate entry for: YOURPODNAME (0.1.0)

解： pod trunk push 时发生此错误，说明该 pod 库在远端已经有了 0.1.0 版本。解决方案有两个：

1. 使用一个远端还没有的版本号
2. 使用 pod trunk delete YOURPODNAME 0.1.0 删除远端的 0.1.0 版本，然后重新进行推送

3. unable to find a pod with name, author, summary, or description matching 'YOURPODNAME'

解： 信息更新不及时导致。

首先删除本地缓存

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

然后执行:

pod update

4.在执行提交代码 pod push的时候可能会出现一些错误：
