override description or stringValue in cocoa?

Question

I want to have an descriptive string for an object in Cocoa. I'm thinking about overriding either the description method or the stringValue method. Which is preferable and why? The only guideline I could find was in here stating

You are discouraged from overriding description.

Is this indeed what you would suggest? Any other preferred overrride point?

Answer 1

I personally override description in virtually all subclasses I create. I guess, like Tom Duckering writes in his comment, that your quote only applies to Managed Objects.

- (NSString *)description
{
    return [NSString stringWithFormat:@"%@ <%p>", NSStringFromClass([self class]), self];
}

Answer 2

description is the way to go, that's what it's called to supply string representation of an object.

- (NSString*)description
{
    return [NSString stringWithFormat:@"%@, %@; %@", a, b, c];
}

I believe suggested by Hillegass' book as well.
