From the docs on NSControl...

"-(void)setCell:(NSCell *)aCell
  Sets the receiver’s cell to aCell. Use this method with great care as
it can irrevocably damage the affected control; specifically, you
should only use this method in initializers for subclasses of
NSControl."

So, I would subclass NSButton, in its -initWithCoder: I would create
the cell and then [self setCell:theCell];
