You could use the "%o" format with sprintf(), or NSString's -
stringWithFormat: to get the octal representation.

If you're using bindings your textField, or even just assigning a new 
value pretty often, a formatter is the way to go. But, you'll need to 
use the above suggestions in a subclass NSFormatter or 
NSNumberFormatter. As far as I know, neither one handles octal by 
default.
