I really enjoyed this week’s NSHipster. It discusses the uses, and misuses, of NSCharacterSet as well as a few other obscure-ish string-related classes.

If you don’t already follow NSHipster, you really should. In the worst case, you already knew about the topic being discussed (but you would already have heard of that, wouldn’t you?) and best case, you learn something super useful.

And if not being wrong isn’t the most important thing about being an NSHipster, then I don’t want to be right!
