Regular expressions in Cocoa using NSPredicate

I spent some time tonight figuring out how to exploit the NSPredicate class from Cocoa for my regular expression needs. I've been trying to do some test-driven development in my iPhone development endeavors and had a need for regular expressions. NSPredicate seems to be the tool for the job, so I wrote up the following wiki page so I could keep this information around.

I even cracked open my "Mastering Regular Expressions" book tonight.  Excellent tome on all things regular expression.  Highly recommended.
