Multiple Fraction Classes
«
on:

I have a fraction class in my FractionTest folder, and another one in my FractionCalculator folder. Are they updating each other? Xcode seems to know they both exist, because when I run Fraction Test, it tells me that there is a previous declaration of the fraction methods such as -(void) add:(Fraction *)f;
How do I straighten this out, so that I am only using one Fraction class, and I'm not having problems with 'previous declarations'?

Xcode doesn't know about classes in other projects. That error message is due to some other problem. Make sure the methods are declared the same way in the interface and implementation sections (remember that one version of the
add:
method returned
void
and the other a
Fraction
object).

Thanks Steve.
You've been amazingly helpful, and I've said so in my Amazon review.
