Recurrence Calculator For iCal - RFC 2445

I need to interpret a RFC2445 recurren开发者_运维技巧ce rule and figure out what dates it occurs on. I don't really want to get into the nitty-gritty of the standard as it seems quite complex, I was wondering if anyone knows of an Objective-C / C / C++ library that I can use to do this?

I have seen DDay.iCal which seems perfect but it's in C#...

Thanks!
