RxSwift开启资源计数的方法:

1). pod文件最后添加:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == 'RxSwift'
      target.build_configurations.each do |config|
        if config.name == 'Debug'
          config.build_settings['OTHER_SWIFT_FLAGS'] ||= ['-D', 'TRACE_RESOURCES']
        end
      end
    end
  end
end

并重新install

2). 找到项目中的RxSwift target,在它的Debug配置中,添加-D TRACE_RESOURCES编译参数(貌似默认就配置上了?)

3). 打印

print("Resource tracing: \(RxSwift.Resources.total)")
