How do you detect words that start with “@” or “#” within an NSString?

I'm building a Twitter iPhone app, and it needs to detect when you enter a hashtag or @-mention within a string in a UITextView.

How do I find all words preceded by the "@" or "#" characters within an NSString?

Thanks for your help!
