Warning Issue: Incomplete Implementation

[mesaBoogie]

Hi,  new to O-C, weekend code warrior as3/C/VB......... so far this is a great book!!!!!!
OK using xCode 4.3
Program 3.2 working fine, makes total sense to me.  but I'm also getting this annoying warning message of Incomplete Implementation?  which if I look a bit deeper, I'm getting Method definition for setNumerator and setDenominator not found? under the @interface.....

But it Works fine

THe compiler is checking to make sure you implemented all the methods specified in your interface section.  Check the spelling and make sure the name match between the two sections.

Cheers,

Steve

How stupid of me, I forgot to call out .........: (int) n and ...........(int) d  in the @interface methods

All better now.... Thanks..

Caught me too. Careless errors... tisk tisk.

Thank you for this. At first I was getting grumpy clearly blaming the book and not myself 

Sure enough I had declared SetNumerator and then called setNumerator. Darn case sensitive programming!! 
Made me chuckle, I am starting to remember why I had given up programming  in the past!


All kidding aside the book is GREAT.
xCode is pretty nice compiler, really helps you find your mistakes. Like it!

Great book so far!  I'm trying to learn O-C as my first language and this book has great explanations of all of the concepts...I am having this same issue (I apologize for the double post but I first posted my code in the "error in program 3.2" section and then I saw this topic) but I'm not finding any error in my spelling...although I'm sure I've done something wrong, I just need a little help finding it.

Thanks,
Michael

I have answered this in your main question thread.

Probably best not to duplicate questions throughout the forum
