How to make a "0000001" NSString

Another noob question from me. I'm trying to create an application that counts, and I'd like to display the number value as som开发者_Go百科ething like "000001". So when it counts up it'll display as "000002".

I'm using something like this right now, but it's not working:

counter.text = [NSString stringWithFormat:@"%000f", count];

The counter.text is a UILabel.

Thanks for the answer.

If you're storing the number as an integer, use the %0xd format (where x is the number of digits) like so:

counter.text = [NSString stringWithFormat:@"%06d", count];

try this

NSLog(@"%.6d",3);
