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，这些依赖项在podspec文件中定义，因此我使用Podfile来管理开发Pod和运行测试所用项目的依赖关系。我正在使用CocoaPods 0.33.1。
我有4个目标：
MFDynamic.iOS（iOS静态库）MFDynamic.iOS.Tests（iOS测试束）MFDynamic.Mac（Mac框架）MFDynamic.Mac.Tests（Mac测试束）
我想要的行为是：
- 针对每个目标指定平台（因为有iOS和OS X目标）。
- 将podspec依赖项作为非测试目标的Pod包含在内。
- 仅在测试目标中指定
Kiwi/XCTest作为依赖项。
然而，无论我尝试了什么，都没有能够编写一个可行的Podfile。 运行pod install从未向我的目标添加CocoaPods的构建阶段，也没有将适当的xcconfig文件添加到项目中。 CocoaPods没有输出任何关于Podfile出现问题的警告。
以下是我最近的一次失败尝试：
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
简化一下就能得到相同的结果（即在项目中没有集成）：
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作为链接到所有目标，因为当项目通过CocoaPods包含在其他人的工作中时，它只获取适当的源文件。因此，即使Kiwi被链接到iOS静态库目标，当与CocoaPods集成时，它也不会被拖入用户的项目中。我真的很想避免这种方法，但如果这是唯一的方法......
无论如何，以这种心态，我已经尝试了以下方法，但运气并不太好：
link_with 'MFDynamic.iOS', 'MFDynamic.Mac', 'MFDynamic.iOS.Tests', 'MFDynamic.Mac.Tests'
podspec :path => '../MFDynamic.podspec'
pod 'Kiwi', '~> 2.2'
在这种情况下，我会遇到一个 pod install 错误：

我的问题：
我想知道正确的方法是什么（见上文）？如何使CocoaPods成功集成到我的项目和iOS/Mac目标中？我已经浏览了Podfile文档，但在这方面发现它不足。
