@techinpark of course it works, I have used for months in my apps, if you use Cocoapods you can set the AFNetworking pod to the last commit of this pull request or to my fork

pod 'AFOAuth2Manager', :git => 'https://github.com/appfluence/AFOAuth2Manager.git', :branch => 'feature/update_to_afnetworking_4'
