I have an app with a preference panel with a text field "FontSize" which is bound to the Shared User Defaults Controller.

If this value changes, my app has to redisplay some text with a new font size.

But how does it know that this value has changed?

Just observe the appropriate keypath (i.e. "values.FontSize") for the defaults controller. -- Jim Hamilton
