Question

I am using Objective-C and trying to create int values that are between 1-99 and if less than 10 I would like them to show as 01, 02, 03, 04, 05, etc. Can anyone tell me how to do that?

Thanks!

Besides PengOne’s answer, you could also use a format string.

NSLog(@"%02d", 3);

says ‘print the following int with at least 2 digits’ and will add the leading 0 if it only has one. It will print

03

Or if you want an NSString,

NSString *tst = [NSString stringWithFormat:@"%02d", 5];
