Conform to this protocol if you want your objects to participate in state restoration. To participate in state restoration, the function registerObjectForStateRestoration must be called for the object.

Method Summary

All Methods Instance Methods Default Methods
Modifier and Type	Method	Description
`default void`	`applicationFinishedRestoringState()`	applicationFinishedRestoringState is called on all restored objects that implement the method after all other object decoding has been done (including the application delegate).
`default void`	`decodeRestorableStateWithCoder(@NotNull NSCoder coder)`
`default void`	`encodeRestorableStateWithCoder(@NotNull NSCoder coder)`	Methods to save and restore state for the object.
`default @Nullable UIObjectRestoration`	`objectRestorationClass()`	The restoration class specifies a class which is consulted during restoration to find/create the object, rather than trying to look it up implicitly
`default @Nullable UIStateRestoring`	`restorationParent()`	The parent property is used to scope the restoration identifier path for an object, to disambiguate it from other objects that might be using the same identifier.

  - applicationFinishedRestoringState
```
default void applicationFinishedRestoringState()
```
    applicationFinishedRestoringState is called on all restored objects that implement the method *after* all other object decoding has been done (including the application delegate). This allows an object to complete setup after state restoration, knowing that all objects from the restoration archive have decoded their state.
  - decodeRestorableStateWithCoder
```
default void decodeRestorableStateWithCoder(@NotNull
                                            @NotNull NSCoder coder)
```
  - encodeRestorableStateWithCoder
```
default void encodeRestorableStateWithCoder(@NotNull
                                            @NotNull NSCoder coder)
```
    Methods to save and restore state for the object. If these aren't implemented, the object can still be referenced by other objects in state restoration archives, but it won't save/restore any state of its own.
  - objectRestorationClass
```
@Nullable
default @Nullable UIObjectRestoration objectRestorationClass()
```
    The restoration class specifies a class which is consulted during restoration to find/create the object, rather than trying to look it up implicitly
  - restorationParent
```
@Nullable
default @Nullable UIStateRestoring restorationParent()
```
    The parent property is used to scope the restoration identifier path for an object, to disambiguate it from other objects that might be using the same identifier. The parent must be a restorable object or a view controller, else it will be ignored.
