为具有多个目标和不同平台的项目编写Podfile

我正在准备一个支持OS X和iOS的pod . 我的pod有自己的一些依赖项，它们在podspec文件中定义，所以我使用Podfile来管理我用来开发pod并运行测试的项目的依赖项 . 我正在使用CocoaPods 0.33.1 .

我有四个目标：

• MFDynamic.iOS （iOS静态库）

• MFDynamic.iOS.Tests （iOS测试包）

• MFDynamic.Mac （Mac框架）

• MFDynamic.Mac.Tests （Mac测试包）

我想要的行为是这样的：

• 指定每个目标的平台（因为有iOS和OS X目标） .

• 将podspec依赖项作为pod包含在非测试目标中 .

• 能够仅将 Kiwi/XCTest 指定为我的测试目标的依赖项 .

However, I haven't been able to write a Podfile that works, whatever I have tried. 正在运行 pod install 永远不会将CocoaPods的构建阶段添加到我的目标，也不会将相应的 xcconfig 文件添加到项目中 . CocoaPods不会输出有关Podfile中任何错误的警告 .

这是我最近的失败尝试：

target 'MFDynamic.iOS' do
  platform :ios, '6.1'
  podspec :path => '../MFDynamic.podspec'
end

target 'MFDynamic.Mac' do
  platform :osx, '10.7'
  podspec :path => '../MFDynamic.podspec'
end

target 'MFDynamic.iOS.Tests' do
  platform :ios, '6.1'
  pod 'Kiwi/XCTest', '~> 2.2.4'
end

target 'MFDynamic.Mac.Tests' do
  platform :osx, '10.7'
  pod 'Kiwi/XCTest', '~> 2.2.4'
end

简化一点会产生相同的结果（即项目中没有集成）：

target 'MFDynamic.iOS' do
  platform :ios, '6.1'
  pod 'AFNetworking', '~> 2.2'
end

target 'MFDynamic.Mac' do
  platform :osx, '10.7'
  pod 'AFNetworking', '~> 2.2'
end

我甚至考虑将所有pod连接到所有目标，因为当项目通过CocoaPods包含在别人的工作中时，它只会抓取相应的源文件 . 因此，即使说，Kiwi与iOS静态库目标相关联，在与CocoaPods集成时也不会将其拖入用户的项目中 . 我真的想避免这种做法，但如果这是唯一的方法......

无论如何，凭借这种心态，我尝试了以下内容，运气不多：

link_with 'MFDynamic.iOS', 'MFDynamic.Mac', 'MFDynamic.iOS.Tests', 'MFDynamic.Mac.Tests'

podspec :path => '../MFDynamic.podspec'
pod 'Kiwi', '~> 2.2'

在那种情况下，我得到一个 pod install 错误：

我的问题：

做我想做的正确方法是什么（见上文）？如何让CocoaPods成功集成到我的项目和iOS / Mac目标中？我已经仔细阅读了Podfile文档，但发现它缺乏这方面的内容 .
