I have a similar task but the opposite format.

   TOTAL:      2
SUBTOTAL:   6.00
     TAX:     0%
    CASH:  12.00

my code is this

NSString* item [NSString stringWithFormat:@"%-10s %@", @"TOTAL",@"2"];

Yet outcome is this

TOTAL:   2
SUBTOTAL:  6.00

UPDATE

I got it to work with this code.

NSString* item [NSString stringWithFormat:@"%12s %7s", [total UTF8String],[amount UTF8String]];

UPDATE QUESTION

What if the text is too long?

THIS TEXT IS TOO LONG

I want it to be

THIS TEXT
IS TOO LONG

unfortunately, the `NSString` does not support the sign `-` (minus) for the strings. there is no warning or error when you try to use, it is just simply not working. – holex Jul 27 '12 at 07:11
There is no way to break a long string using format specifiers. – Vadim Jul 27 '12 at 07:33
But would it be possible if i won't use format specifiers? even though format specifiers is not on my mind when thinking for a solution. – n0minal Jul 27 '12 at 07:44
The answer in the link states that you need to convert your NSString's to C-Strings using `UTF8String`. – TheAmateurProgrammer Jul 27 '12 at 06:37
yes. i did. but what i want is the opposite format stated on the link. – n0minal Jul 27 '12 at 06:47
Try put an empty string in front, something like `@"%-10s%@ %@", @"", @"TOTAL", @"2"` – TheAmateurProgrammer Jul 27 '12 at 06:50
