Your best bet is probably Gnu MP. It can do whatever precision you want and has a fairly large community of developers. I'm sure there are Objective-C wrappers available for it as well.

Anyone know of any? I'm trying to rewrite an algorithm I made for NSUIntegers to use ever larger values for cryptanalysis.
