what else text editors can be used to editor Objective-C code except xcode

I am new to mac, my question is what else text editors can be used to edit Objective-C code except xcode. And which one is the best for prod开发者_开发技巧uctively editing source code?

Have you tried TextMate?

What text editors can't edit c code?

I'd recommend vim, emacs or textmate.

Emacs, obviously, tho' heretics will advise Vi(m).
