Cocoapods: turning MagicalRecord logging off

Question

Turning MagicalRecord logging off requires a #define to be made before it is first included in the project, but in the case of a project managed by Cocoapods I have no access to add a #define in the Pods project. How do I turn logging off completely in this scenario?

Took me a few hours to figure out a way to do it, posting here in the hope it will help others.

EDIT: this is not a duplicate as it discusses turning logging off under Cocoapods

You can use a post_install hook to modify pretty much any build setting. Just add this code to your Podfile:

post_install do |installer|   target = installer.project.targets.find{|t| t.to_s == "Pods-MagicalRecord"}     target.build_configurations.each do |config|         s = config.build_settings['GCC_PREPROCESSOR_DEFINITIONS']         s = [ '$(inherited)' ] if s == nil;         s.push('MR_ENABLE_ACTIVE_RECORD_LOGGING=0') if config.to_s == "Debug";         config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] = s     end end 

Note that this will only disable logging in the debug configuration - logging is disabled by default in the release configuration.
