spec.platform = :ios
spec.platform = :osx

spec.ios.deployment_target = '6.0'
spec.osx.deployment_target = '10.8'

编译设置

• dependency 依赖的其他库
  spec.dependency 'AFNetworking', '~> 1.0'
spec.ios.dependency 'MBProgressHUD', '~> 0.5'

• frameworks 依赖的framework
  spec.ios.framework = 'CFNetwork'
spec.frameworks = 'QuartzCore', 'CoreData'

  spe.ios.library = 'xml2'
spe.libraries = 'xml2', 'z'

  spec.compiler_flags = '-Wno-format', '-DOS_OBJECT_USE_OBJC=0'

• prefix_header_contents pch预编译头文件内容
  spec.prefix_header_contents = '#import <UIKit/UIKit.h>'

• prefix_header_file pch预编译头文件路径
  spec.prefix_header_file = 'iphone/include/prefix.pch'

文件样式

Podspecs应该放在repository的根目录
*匹配所有，?匹配一个任意字符，[^a-d]匹配集合内字符 {p,q}匹配p或q \跳过下一个

"JSONKit.?" 所有的jsonkit为名的文件
"*" 所有文件
"*.{h,m}" 所有的.h.m文件

• source_files 源文件
  spec.source_files = 'Classes/**/*.{h,m}'
spec.source_files = 'Classes/**/*.{h,m}', 'More_Classes/**/*.{h,m}'

• public_header_files 公开头文件 用户可以引入查看的头文件 ，不设置则搜有的头文件都可以引入
  spec.public_header_files = 'Headers/Public/*.h'

• private_header_files 私有头文件 用户不可以引入的头文件
  spec.private_header_files = 'Headers/Private/*.h'

• resource_bundles 资源包 推荐使用

spec.resource_bundles = {
   'MapBox' => ['MapView/Map/Resources/*.png'],
   'OtherResources' => ['MapView/Map/OtherResources/*.png']
 }

• resources 资源包
  spec.resource = 'MJRefresh/MJRefresh.bundle'

• subspec 子模块依赖
