Discussion
You can use this method instead of, or in addition to, the encode and restore methods to save and restore the state of your responder. The key paths you return must refer to attributes that are key-value coding and key-value observing compliant. To learn more about these mechanisms, see Key-Value Coding Programming Guide and Key-Value Observing Programming Guide.
When changes are detected, the specified attributes are automatically written to disk with the rest of the application’s interface-related state. At launch time, the attributes are automatically restored to their previous values.
