I'll appreciate someone to help me understand the problem and suggest solution.
I'm trying to send a msg. to Pawn1 thru Pawn16 classes, but it doesn't work from inside the loop.
Thanks.


- (IBAction)resetAll: (id)sender {

// 	[toPawn1 showYourself];  		//--- This works fine.
// 	.......
// 	[toPawn16 showYourself];

/ but the following generates a warning: 'NSMutableString' may not respond to '-showYourself'

for (i = 1; i <= 16; ++i) {
NSMutableString *str = [NSMutableString stringWithFormat: @"toPawn %i", i];
[ [str className] showYourself];
[str release];
}
}

i'm not a pro, but i think i understand the problem. unfortunately, i don't know how to solve it.


ok, here goes:
className returns the name of the class that your object (in this case str) was made from, which is NSMutableString. the second line in the for loop sends showYourself to NSMutableString which obviously does not know how to respond, so you get that warning. _______________________________________________
