The nib can instantiate the formatter and then you should change class of the
formatter in the nib from NumberFormatter to MyIntNumberFormatter. In other
words the nib or xib should already contain the formatter, if not then create
one. Connect the formatter to your control as you normally would. Then set the
class of the formatter to your custom class. When the nib awakes it will
instantiate a formatter using your custom subclass.
