Podfile仓库版本控制

1. 使用最新版本

pod 'SSZipArchive'

2. 使用固定版本

pod 'Objection', '0.9'

3. 比较符号

 '> 0.1' Any version higher than 0.1
 '>= 0.1' Version 0.1 and any higher version
 '< 0.1' Any version lower than 0.1
 '<= 0.1' Version 0.1 and any lower version

4. ~>符号

 '~> 0.1.2' Version 0.1.2 and the versions up to 0.2, not including 0.2 and higher
 '~> 0.1' Version 0.1 and the versions up to 1.0, not including 1.0 and higher
 '~> 0' Version 0 and higher, this is basically the same as not having it.

5. 开发模式，可源码调试

pod 'Alamofire', :path => '~/Documents/Alamofire'

6. 指定某个git仓库

pod 'Alamofire', :git => 'https://github.com/Alamofire/Alamofire.git'

7. 指定仓库的某个分支

pod 'Alamofire', :git => 'https://github.com/Alamofire/Alamofire.git', :branch => 'dev'

8. 指定仓库的某个tag

pod 'Alamofire', :git => 'https://github.com/Alamofire/Alamofire.git', :tag => '3.1.1'

9. 指定仓库的某个提交

pod 'Alamofire', :git => 'https://github.com/Alamofire/Alamofire.git', :commit => '0f506b1c45'
