Instance Method


Restores the interface-related state of the responder.


func restoreState(with coder: NSCoder)



The coder object to use to restore the responder’s interface-related state.


This method is part of the window restoration system and is called at launch time to restore the visual state of your responder object. The default implementation does nothing but specific subclasses (such as NSView and NSWindow) override it and 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 was saved in the encodeRestorableState(with:) method. You can also use this method to reconfigure the responder to its previous appearance.

For information about using a coder object to read data from an archive, see Archives and Serializations Programming Guide.
