Cocoapods: turning MagicalRecord logging off

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    endend

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

In my case, I was building a library that depended on MagicalRecord. I didn't want my users to have to add a post_install in their Podfile to silence the noisy logging, so I added it to my podspec instead.

  s.prefix_header_contents = '#define MR_ENABLE_ACTIVE_RECORD_LOGGING 0'

This automatically adds this #define statement to Pods-prefix.pch, which silences MagicalRecord logging in projects that use my pod.

I updated ank's answer for those using the new cocoapods version alongside MagicalRecord 2.3.0:

post_install do |installer|  target = installer.pods_project.targets.find{|t| t.to_s == "MagicalRecord"}  target.build_configurations.each do |config|    s = config.build_settings['GCC_PREPROCESSOR_DEFINITIONS']    s = [ '$(inherited)' ] if s == nil;    s.push('MR_LOGGING_DISABLED=1') if config.to_s == "Debug";    config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] = s  endend

Changes:

• project renamed to pods_project
• Target Pods-MagicalRecord renamed to MagicalRecord
• Macro MR_ENABLE_ACTIVE_RECORD_LOGGING renamed to MR_LOGGING_DISABLED and value changed from 0 to 1
