Instance Method

decodeRestorableState(with:)

Decodes and restores state-related information for the object.

Declaration

optional func decodeRestorableState(with coder: NSCoder)

Parameters

coder

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

Discussion

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.
