For years, the "Implementing Validation" section of Apple's "User
Interface Validation" document has said the following:
"Before it is displayed, a user interface item checks to see if its
target implements validateUserInterfaceItem:. If it does, then the
enabled status of the item is determined by the return value of the
method. You can therefore conditionally enable or disable an item by
implementing validateUserInterfaceItem: in the target object."
This has never been true. Right?
It depends on the sort of user interface element.
This does work for menu items and tab bar items...
