Cocoapods optimization level for schemes

问题

Looking at the project file for Cocoapods Pods.xcodeproj it looks like every single scheme for every library (except for Debug scheme) has an optimization level of Fastest, Smallest.

Is there a quick and easy way to change the Podfile or some other configuration of Cocoapods so that the optimization level is None for specific schemes when I use pod install?

回答1:

I use post_install hook in Podfile. Like this:

post_install do |installer|
    installer.pods_project.build_configurations.each do |config|
        if config.name.include?("Debug")
            config.build_settings['GCC_OPTIMIZATION_LEVEL'] = '0'
            config.build_settings['SWIFT_OPTIMIZATION_LEVEL'] = '-Onone'
        end
    end
end

EDIT GCC_OPTIMIZATION_LEVEL is ignored for Swift Pods. If you're using Swift Pods you also need to set SWIFT_OPTIMIZATION_LEVEL.

To anybody seeing this using cocoapods 0.38.0 or later:

Use "pods_project" instead of "project"

The previous answers use the word "project" (installer.project.build_configurations.each)

Project was deprecated and replaced with pods_project. https://github.com/CocoaPods/CocoaPods/issues/3747

post_install do |installer|
  installer.pods_project.build_configurations.each do |config|
    if config.name.include?("Debug")
      config.build_settings['GCC_OPTIMIZATION_LEVEL'] = '0'
    end
  end
end

If you also want the DEBUG macro added for debugging with assertions enabled, you can use the following script:

post_install do |installer|
  installer.project.build_configurations.each do |config|
    if config.name.include?("Debug")
      # Set optimization level for project
      config.build_settings['GCC_OPTIMIZATION_LEVEL'] = '0'

      # Add DEBUG to custom configurations containing 'Debug'
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)']
      if !config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'].include? 'DEBUG=1'
        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] << 'DEBUG=1'
      end
    end
  end

  installer.project.targets.each do |target|
    target.build_configurations.each do |config|
        if config.name.include?("Debug")
          # Set optimization level for target
          config.build_settings['GCC_OPTIMIZATION_LEVEL'] = '0'

          # Add DEBUG to custom configurations containing 'Debug'
          config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)']
          if !config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'].include? 'DEBUG=1'
            config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] << 'DEBUG=1'
          end

          # Enable assertions for target
          config.build_settings['ENABLE_NS_ASSERTIONS'] = 'YES'

          config.build_settings['OTHER_CFLAGS'] ||= ['$(inherited)']
          if config.build_settings['OTHER_CFLAGS'].include? '-DNS_BLOCK_ASSERTIONS=1'
            config.build_settings['OTHER_CFLAGS'].delete('-DNS_BLOCK_ASSERTIONS=1')
          end
        end
      end
  end
end

Instead of post_install you can add following line to Podfile:

project 'ProjectName', 'DebugConfigurationName' => :debug
