Question

My program works OK, but I get this warning when compiling:

format not a string literal and no format arguments

RomanosBasicos is an array of Strings:

RomanosBasicos=[[NSArray alloc] initWithObjects:@"M",@"CM",@"D",@"CD",@"C",@"XC",@"L",@"XL",@"X",@"IX",@"V",@"IV",@"I" , nil];

and I get the warning in this line:

temp = [temp stringByAppendingFormat:[RomanosBasicos objectAtIndex:i]];

Thanks for your help!.

Answer 1

instead of

temp = [temp stringByAppendingFormat:[RomanosBasicos objectAtIndex:i]];

use

temp = [temp stringByAppendingString:[RomanosBasicos objectAtIndex:i]];

But if you want to use stringByAooendingFormat: then you have to do this

temp = [temp stringByAppendingFormat:@"%@", [RomanosBasicos objectAtIndex:i]];

I think you get it now what that warning means.
