Question

i have this code:

NSString * firstdDigitTest = [numberString substringToIndex:1];

        if (! [firstdDigitTest isEqualToString:@"0"])
        {
            numberString = [numberString substringFromIndex:1];
            self.firstImageName = [namefile stringByAppendingString:firstdDigitTest];

        }

        self.number = [numberString integerValue];

i check if the first number is not 0 and if it’s not 0 i need to insert it to the firstImageName. But when i do it (using the substringFromIndex) and i try to use integerValue it’s dosent work!
without the substringFromIndex it’s works! 🙁

Answer 1

NSString *str0 = @"XXX10098";
NSString *str1 = [str0 substringWithRange:NSMakeRange(4, str0.length-4)];
NSLog(@"%@", str1);

NSLog(@"%d", [str1 intValue]);
