Thanks a lot!
Anyway, this can still be more compact. I just posted a one-line solution at

"there is a dot followed by an asterisk (which means “one or more characters”)"

Actually, * is "zero or more", + is "one or more".

For anybody reading this after iPhone OS 3.0 was released, NSPredicate and NSComparisonPredicate are available on the iPhone.

iPhone OS Note: The predicate classes—NSPredicate, NSCompoundPredicate, and NSComparisonPredicate—are present only in the Mac OS X version of Foundation.

Hi,

Thanks for the example, it was very useful, I tried it on the simulator and worked perfectly. However, I'm running into this error when I try it on the phone:

compiling XXXXXXXXXX.m NSPredicate undeclared (first use in this function) regextest undeclared (first use in this function) warning: control reaches end of non-void function

Any ideas?

I am really glad I bumped into this page while looking to support regex in my app. Now I don’t have to link and manage yet another 3rd party framework.

The backspace in the metacharacters (like in “\d” for a number) has to be escaped in the @”…” string. Confusing if you aren’t used to that.

It appears that my problem is with multi line matching, rather than text encoding.
