iOS Going a bit nuts with a stringWithFormat...

[ulbador]

Is there a way to auto-pad this?

int checksum = 15;
[NSString stringWithFormat:@"%X",checksum];

This comes out to be "0F" in hex. But as is, it just returns "F".

"%02X". Refer to the printf documentation:

Thanks for this. It was exactly what I needed.
