Format string, integer with leading zeros

Question

Hi all! I Use this code:

NSString* strName = [NSString stringWithFormat:@"img_00%d.jpg", pp];

and works fine, but if pp took the value of 10 for example I wish have img_010.jpg as result, and not img_0010.jpg... how can I format the string??

thanks

Answer 1

Use the format string "img_%03d.jpg" to get decimal numbers with three digits and leading zeros.
