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. (:

Basically, I have an array of buttons I want to iterate and highlight (among other things) one after another, with a delay in-between. Seems like an easy task, but I can't seem to manage to get it to work cleanly while still being responsive.

Using Objective-C on my iPhone, is there a built-in method for NSString that finds a string appearing BETWEEN 2 other stings?
Search "my dog is my cat's best friend"... and return everything between "dog" and "best".
Or will I have to write my own? Any good ideas on where to start?
Thanks.
