Hi. I am trying to iterate through the ASCII codes (just as an experiment) and not sure how I can express the code in the string literal. For example, within the for loop, with i going from 1 to 255, I want to print: Code: NSLog(@"Character is \x..." and that is where I am stuck. For instance, if i = 65 (which is ASCII character "A") then the hex value is 41. Literally, the string would be Code: @"\x41" but since I am using the variable i to iterate, how do I 1) convert the decimal to hex and 2) express that inside the NSLog string literal? I Googled around and found two class methods for the dec/hex conversion but the above is still unclear. I suspect I need to cast the string to a value and then also somehow "escape" that value into the string literal. Code: NSString * decimalString = [NSString stringWithFormat:@"%d", number]; NSString * hexString = [NSString stringWithFormat:@"%x", number]; Thanks.
