Create a stopwatch with zeros before numbers

I've made a sort of "stopwatch" in my app. Basically, I have an int (let's call it number) that increments every 0.1 seconds, and a label (let's call it label) that updates when number does. label's text is the String form of number.

This is working fine, but I'd like to get my label to have the "old-school video game" format, with zeros before the numbers themselves. For example, when number is actually 4, I want label to say "00004." When number is 2,341, I want label to say "02341." Etc.

How do I do this? I can take answers in either Swift or Objective-C.

String formatting references the IEEE standard. See here for more details: http://pubs.opengroup.org/onlinepubs/009695399/functions/printf.html – Phillip Mills May 25 '16 at 17:51
See `NSNumberFormatter`. – rmaddy May 25 '16 at 17:54
@JeremyAnantharaj That worked, thanks. I'll take it as the solution. – Christian Kreiter May 25 '16 at 17:56
