While there isn’t a standard way to do this with the Apple frameworks, you should certainly check out CocoaDev’s entry and discussion on the topic: BaseSixtyFour. They have plenty of ways to work this out, and the last comment there doesn’t require libcrypto, or any external frameworks (which, on iOS, is a good start). It’s definitely worth a look.
Update: Or even better, check out Base64 encoding options on Mac and iPhone on CocoaWithLove, as it includes excellent source code.
