Should I autorelease before return form -(NSString*)description?

Question

Today i was overwriting -(NSString*)description method and i wondered if need to autorelease this string before returning it.

-(NSString*)description {
    NSMutableString *response = [[NSMutableString alloc] init];
    // perform appends
    return [response autorelease];
}

Yes, as per ownership rule your function must not delegate the ownership of the returned string to the caller.
