将自己的代码添加cocoapods支持

先做记录之用
1.更新cocoapods至最新版本

$sudo gem install cocoa pods

2.注册邮箱，xxxx为git用户名

pod trunk register 123456@qq.com 'xxxx' --verbose 

3.查看注册信息

pod trunk me

4.创建 .spec文件

pod spec create ViewController  

5.编辑文件ViewController.spec

vim ViewController.podspec
//下面是文件内容
Pod::Spec.new do |s|
s.name = 'xxxxxxx'
s.version = '1.0.1'
s.license = 'MIT'
s.summary = 'A view like UIAlertViewController on iOS.'
s.homepage = 'https://github.com/xxxxx/ViewControllerController'
s.authors = { 'xxxxx' => '123456@qq.com' }
s.source = { :git => 'https://github.com/xxxxx/ViewControllerController.git', :tag => s.version.to_s }
s.requires_arc = true
s.ios.deployment_target = '7.0'
s.source_files = 'ViewControllerController/*.{h,m}'
end

6.验证xxxxx.spec文件编写是否正确

pod lib lint ViewController.podspec

7.推送到github

git tag '1.0.1'
git push --tags

8.把编写的文件告诉Cocoapods

pod trunk push viewController.podspec

[注意事项]
1.pod setup卡住问题
执行

$ git clone https://git.coding.net/CocoaPods/Specs.git ~/.cocoapods/repos/master

[!] Unable to satisfy the following requirements:
- `AFNetworking (~> 2.3.1)` required by `Podfile`
Specs satisfying the `AFNetworking (~> 2.3.1)` dependency were found, but they required a higher minimum deployment target.

解决方案：Podfile 文件 中 platform:ios, ‘8.0’ 后边的 8.0 是平台版本号 ，一定要加上
