iOS NSInteger to NSString with spaces

[nomar383]

I humbly come before the macrumors programming gods with another inquiry

Basically, I have an NSInteger that holds the score for the app I'm working on. It starts at 0 and can go up to 6 digits in length. I have it displaying in a UILabel (via a NSString obviously) and I need to put 2 spaces between each displayed digit. So it would display something like this:

0 0 0 0 1 5

I can get it to display the number just fine, no issue there. I'm just trying to wrap my head around putting 2 spaces between each individual digit. I think NSNumberFormatter may be of help, but I'm getting lost looking at the documentation for it. Any help/advice?

EDIT: I also need to display leading zeros if possible

This should do what you want:

NSInteger num = 15;
NSMutableString *str = [NSMutableString stringWithFormat:@"%06d", num];
for (NSInteger i=1; i<[str length]; i+=2)
    [str insertString:@" " atIndex:i];

The %06d part is how you pad it with zeros.
