第一次使用cocoapods,这篇博客写得比较详细:http://www.cocoachina.com/newbie/basic/2014/0107/7663.html,想要了解更多,https://github.com/CocoaPods/CocoaPods/wiki,发现添加jsonkit后导致编译不通过,
post_install do |installer_representation|
installer_representation.project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings[‘CLANG_WARN_DIRECT_OBJC_ISA_USAGE‘] = ‘YES‘ end end
end 可以解决,
