Exceptions vs. pointers to error objects

Subject: Exceptions vs. pointers to error objects

I'm writing an API to communicate with a web service, and I was just wondering what the thinking is on exceptions vs. functions returning an NSError in some way. Basically I'm wondering what people's opinions are on a function throwing an exception on failure, vs returning an NSError object.

Perhaps there is already a policy on when each is to be used. If so, please enlighten me. :)

Thanks,
Colin
