Mark down editor for objective-c

I need to implement a markdown editor in objective-c, that various buttons can be pressed after selecting text and then the markdown is applied to the selection. So far I have easily gotten bold and italics, and more complicatedly, numbered lists, quote segments, code segments. I am guessing this will involve using regular expressions, so far I've avoided this but the code is quite ugly.

I’m not aware of an Objective-C library for Markdown. That said, since Objective-C is a superset of C, you could try a plain C Markdown library:

• peg-markdown
• libupskirt

There's an Objective-C library named markdownlive, built around Discount.
