Provided Methods

fn findInteraction_sessionForView( &self, interaction: &UIFindInteraction, view: &UIView, ) -> Option<Retained<UIFindSession>>

where Self: Sized + Message,

Available on crate features UIFindSession and UIResponder and UIView only.

Called when a find session is requested to begin by the user. Return an instance of a UIFindSession implementation to allow the find session to begin, otherwise return nil to prevent the system find panel from appearing.

fn findInteraction_didBeginFindSession( &self, interaction: &UIFindInteraction, session: &UIFindSession, )

where Self: Sized + Message,

Available on crate feature UIFindSession only.

Called when the search operation begins (and the system search UI appears). This would be a good time to decorate your view to indicate that a search operation is about to occur. System text elements will apply a dimming view around all non-highlighted search results, for instance.

fn findInteraction_didEndFindSession( &self, interaction: &UIFindInteraction, session: &UIFindSession, )

where Self: Sized + Message,

Available on crate feature UIFindSession only.

Called when the current search session has changed or ended. This would be a good time to remove all decorations applied to found search results, and any decorations added when the search operation began (such as a dimming view).
