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

我已经四处转转了几天，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 

在上面运行pod update之后，我得到以下输出：

 Update all pods Analyzing dependencies CocoaPods 0.35.0 is available. To update use: `sudo gem install cocoapods` For more information see http://blog.cocoapods.org and the CHANGELOG for this version http://git.io/BaH8pQ. Fetching podspec for `SCCommon` from `../SCCommon.podspec` Downloading dependencies Using AFNetworking (1.2.1) Using Mantle (1.5.1) Using OCMock (2.2.3) Using PubNub (3.5.5) Using SCCommon (0.3) Generating Pods project Setting preprocessor macro for Pods-SCCommon-UnitTests... Release configuration... $(inherited) SC_DEBUG_SCCOMMON=1 FOOBAR --- Debug configuration... DEBUG=1 $(inherited) --- Integrating client project 

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？

Answer 1

以我添加宏的方式找到了我的具体问题的答案。 我不得不将config.build_settings ...行分成两行，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，我也在错误的目标上设置定义。 既然这两个问题都解决了，我正式解散了！ 好极了！
