How can you return an array value (witch is a number) as a string?
Current code:
return [numbers objectAtIndex:row];
Have also tried:
return @"%@", [numbers objectAtIndex:row];
With no luck..
Thanks :) PS: Yes, I am stupid. (:

You again?! :) Definitely keep asking questions here, but If you're new to Objective-C, I cannot recommend highly enough this book: amazon.com/Cocoa-Programming-Mac-OS-3rd/dp/0321503619. Spend a couple hours and plow through the tutorials. It got me up to speed a few years ago on Obj-C/Cocoa in a small number of hours and was hugely beneficial.Ben Zotto– Ben Zotto2010-02-09 17:57:48 +00:00Commented Feb 9, 2010 at 17:57

I will get a book, the only thing is that I live in Norway, and we don't have many book stores with programming books ;)Emil– Emil2010-02-09 18:00:33 +00:00Commented Feb 9, 2010 at 18:00

If you can find an old copy on eBay.no or wherever, it's really worth every penny.Ben Zotto– Ben Zotto2010-02-09 18:03:28 +00:00Commented Feb 9, 2010 at 18:03

return [[numbers objectAtIndex:row] description];
In C / ObjC / C++ / Javascript / D / many other C-based languages, the comma operator does not create an array / tuple.
(a,b,c,d,e)
is similar to
e
(while evaluating a and b and c and d as a side-effect).

+1 for talking about the unloved comma operator. But beware newbies that we don't write
(a, b, c, d, e) almost ever in C languages.

Btw, objectsAtIndex is not valid :)

You really don't want to use
-description. Use -stringValue instead.bbum
Because -description is a method that is intended to describe an object in a debugging or logging role. -stringValue is intended for purposes of display and the like.
