IOS - using Twitter reverse auth in an application that does not use ARC

I have an application that does not use ARC. Now I want to integrate twitter infrastructure in order to get authentication access token in my application. I just got the application with reverse connection enabled. I tried this example - https://github.com/seancook/TWiOS5ReverseAuthExample which works fine, but when I try to integrate it with my project, it gives me a bunch of memory problems and BAD_ACCESSes, obviously, because the ARC code is included. Can I use it in my application?

Thanks, and any feedback would be much appreciated. Yours faithfully
