为什么我的cocoapods post_install挂钩不更新我的预处理器宏？

Question

我已经四处转转了几天,现在试图找出为什么我的post_install挂钩没有产生我期待的输出.这是我的Podfile:

source 'https://github.com/CocoaPods/Specs.git'

target "SCCommon" do
  platform :ios, "6.0"
  pod 'AFNetworking', '~> 1.2.1'
  pod 'Mantle', '~> 1.3'
  pod 'PubNub', '3.5.5'
end

target "SCCommon-TestHarness" do
  platform :ios, "6.0"
# inhibit_all_warnings!
  pod 'SCCommon', :path => '../SCCommon.podspec'
end

target "SCCommon-UnitTests" do
  platform :ios, "6.0"
# inhibit_all_warnings!
  pod 'OCMock', '2.2.3'
  pod 'SCCommon', :path => '../SCCommon.podspec'
end

post_install do |installer_representation|
  installer_representation.project.targets.each do |target|
    if target.name == 'Pods-SCCommon-UnitTests'
      puts "Setting preprocessor macro for #{target.name}..."
      target.build_configurations.each do |config|
        puts "#{config} configuration..."
        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)','SC_DEBUG_SCCOMMON=1','FOOBAR']
        puts config.build_settings['GCC_PREPROCESSOR_DEFINITIONS']
        puts '---'
      end
    end
  end
end

运行pod update上面的内容后,我得到以下输出:

Update all pods

CocoaPods 0.35.0 is available.
To update use: `sudo gem install cocoapods`

我的问题是:为什么不使用新的宏定义更新Debug配置？您可以在输出中看到正确设置了Release配置,但没有调试.

有任何想法吗？

在我添加宏的方式中找到了我的特定问题的答案。我不得不将这config.build_settings ...条线分成两行，如下所示：

post_install do |installer_representation|
  installer_representation.project.targets.each do |target|
    if target.name == 'Pods-SCCommon-UnitTests-SCCommon'
      puts "Setting preprocessor macro for #{target.name}..."
      target.build_configurations.each do |config|
        puts "#{config} configuration..."
        puts "before: #{config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'].inspect}"
        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)']
        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] << 'SC_DEBUG_SCCOMMON'
        puts "after: #{config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'].inspect}"
        puts '---'
      end
    end
  end
end

作为旁注，我还在错误的目标上设置了定义。现在这两个问题都解决了，我正式解脱了！好极了！
