为什么我的 cocoapods post_install 钩子没有更新我的预处理器宏? [英] Why isn't my cocoapods post_install hook updating my preprocessor macros?

问题描述

我已经转了几天，想弄清楚为什么我的 post_install 钩子没有产生我期望的输出.这是我的 Podfile:

I've been going round and round for a couple days now trying to figure out why my post_install hook isn't producing the output I'm expecting. Here's my 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 后，我得到以下输出:

After running pod update on the above, I get the following output:

Update all pods

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

我的问题是:为什么 Debug 配置没有使用新的宏定义更新?您可以在输出中看到 Release 配置设置正确，但不是 Debug.

The question I have is: Why isn't the Debug configuration updating with the new macro definitions? You can see in the output that the Release configuration is setup correctly, but not Debug.

有什么想法吗?

推荐答案

在我添加宏的方式中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:

Found the answer to my specific issue in the way I was adding macros. I had to break the config.build_settings ... line into two lines like so:

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

顺便说一句，我也在错误的目标上设置了定义.既然这两个问题都解决了，我正式解脱了！耶！

As a side note, I was also setting the definition on the wrong target. Now that both of those issues are resolved, I am officially unstuck! Yay!
