iOS 记录pod组件化学习历程

为啥要pod组件化？

让我们的项目模块化，单个功能独立，能够拆分组合
项目结构更加清晰
多人合作责任更加明确，提高解决问题的效率
通用功能合成组件，让我们以后做其他项目时，可以快速集成

什么时候组件化？

• 从已有的项目中抽离出单独的模块，然后组件化
• 如果我们准备实现某个单独的功能，我们可以使用命令pod lib create 我的组件名称创建一个pod项目，然后在这个项目里实现这个功能，这样的好处就是组件化之后，这个项目就是我们组件化的demo，给到别人，别人从demo中能够理解和使用我们的组件

示列：本地化组件

这里我拿刚写好的一个demo项目来做示列

image.png

主要功能就是实现蓝牙与硬件的通信，功能已经完成
先抽离功能文件，以下就是这个功能的所有文件，这些文件都要放到组件的资源文件中

image.png

本地化组件比较简单，最主要的就是.podspec文件，我们最后创建的目录结构

image.png

先看看.podspec文件中的内容

#
# Be sure to run `pod lib lint TestPod.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 https://guides.cocoapods.org/syntax/podspec.html
#

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

# 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]/TestPod'
  # 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]/TestPod.git', :tag => s.version.to_s }
  # s.social_media_url = 'https://twitter.com/'

  s.ios.deployment_target = '8.0'

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

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

注意以上需要修改的地方，关于LICENSE文件内容

然后我们创建一个demo，来使用组件

image.png

在demo项目下创建podfile文件

image.png

终端pod install，在项目中使用组件

image.png

对外暴露的class需要使用public进行修饰，如果外部可以继承使用open修饰
到此本地组件化结束，很简单四不四

如果我们想使用之前的命令pod lib create 我的组件名来创建一个组件demo项目也可以，按照提示，我们将生成一个demo项目

image.png

然后将之前抽离的文件，放到这个Class文件中就可以了，也是很简单哒

让我们的组件关联远程仓库

1：创建一个远程仓库makePod，码云，GitHub上都可以，复制远程仓库连接

image.png

2：初始化本地仓库，将本地代码上传到远程仓库

git init
git add .
git commit -m '说明'
git tag '0.1.0' -m '这个标签要打上去哦，因为. podspec文件里有指定tag'
git push -u origin master
// tag也要提交上去哦
git push --tag  

3：添加组件到本地仓库，~/.cocoapods中可以看到这个组件
pod repo add makeTestPod https://github.com/xxxxxx/makePod.git

image.png

4：验证组件

// 验证本地仓库，忽略警告
pod lib lint --allow-warnings --verbose
// 验证远程仓库
pod spec lint --allow-warnings --verbose

5：上传到远程私有索引库
pod repo push makeTestPod TestPod.podspec

image.png

6：查找我们的组件
pod search makeTestPod
报错
[!] Unable to find a pod with name, author, summary, or description matching LMBlueChargeTest
这个错误是没有找到我们的库，不过没关系，我们直接在项目中用试试，修改podfile文件

image.png

pod install
