Saves the interface-related state of the responder.
- macOS 10.7+
The coder object in which to save the responder’s interface-related state.
This method is part of the window restoration system and is called at appropriate times to save the visual state of your responder to the specified archive. The default implementation of this method does nothing but specific subclasses (such as
NSWindow) override it to save important state information. Therefore, if you override this method, you should always call
super at some point in your implementation.
Subclasses can override this method and use it to restore any information that would be needed to restore the responder to its current state. For example, the
NSTab class uses this method to save information about the currently selected tab. You must store enough data to reconfigure the responder and return it to its current state during a subsequent launch of the application.
