XCode 报错：library not found for -lstdc++.6.0.9

ld: library not found for -lstdc++.6.0.9

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Xcode10中已去除这个stdc++.6.0.9这个库。报这个错一般是项目中有用到stdc++.6.0.9

在Podfile中增加post_install的hook，将stdc++.6.0.9替换成c++。

post_install do |installer_representation|
  installer_representation.pods_project.targets.each do |target|
    #TargetName为自己项目的Target名
    if target.name == 'Pods-TargetName'
      target.build_configurations.each do |config|
        xcconfig_path = config.base_configuration_reference.real_path
        xcconfig = File.read(xcconfig_path)
        new_xcconfig = xcconfig.sub('stdc++.6.0.9', 'c++')
        File.open(xcconfig_path, "w") { |file| file << new_xcconfig }
      end
    end
  end
end
