Provided Methods

fn restorationParent( &self, ) -> Option<Retained<ProtocolObject<dyn UIStateRestoring>>>

where Self: Sized + Message,

fn objectRestorationClass(&self) -> Option<&'static AnyClass>

where Self: Sized + Message,

unsafe fn encodeRestorableStateWithCoder(&self, coder: &NSCoder)

where Self: Sized + Message,

Safety

coder possibly has further requirements.

impl ProtocolType for dyn UIStateRestoring

const NAME: &'static str = "UIStateRestoring"

The name of the Objective-C protocol that this type represents.

fn protocol() -> Option<&'static AnyProtocol>

Get a reference to the Objective-C protocol object that this type represents.

Dyn Compatibility
