This results in strings like " 8" instead of "08".
It should really be:
NSString *foo = [NSString stringWithFormat:@"d", aSignedInt];
Otherwise it pads with spaces. For more on the format, look at:
http://developer.apple.com/documentation/Cocoa/Conceptual/Strings/Articles/formatSpecifiers.html#//apple_ref/doc/uid/TP40004265-SW1
and "man 3 printf" from a terminal window.
