Thanks for this! I just started on my 2nd app.. (first is in review and probably will be for another week at least, but I'll post an image if/when it gets approved) ...and I wanted to use regex but when I added the regexkitlite.h and .m files I got 13 errors, figured I did something wrong and almost gave up. Then I remembered you had a snippet posted and your walkthrough at the end saved me, thanks!
