What are the options available of parsing and/or tokenizing Objective-C on iPhone?
Essentially I'm thinking of parsing/tokenizing enough to power syntax highlighting and autocompletion at somewhat the same level as Xcode does.

I know the topic is old, but this might help someone else.
Apple already provides the (very nice) CFStringTokenizer, with support for multiple languages. Here's a good presentation on that, including sample code. In case tokenization is enough, that should do it.
If parsing is required however (it shouldn't for syntax highlight) there's ParseKit or C-based solutions, such as YACC.
Best.
