Instance Method


Decodes and restores state-related information for the object.


optional func decodeRestorableState(with coder: NSCoder)



The coder object to use to decode the state of the view.


If your app supports state restoration, you can implement this method on any object for which you also overrode the encodeRestorableState(with:) method. Your implementation of this method should read any saved state information from the archive and use it to restore the object to its previous configuration. If your encodeRestorableState(with:) method called super, this method should similarly call super at some point in its implementation.
