Provided Methods

fn contextMenuInteraction_configurationForMenuAtLocation( &self, interaction: &UIContextMenuInteraction, location: CGPoint, ) -> Option<Retained<UIContextMenuConfiguration>>

where Self: Sized + Message,

Available on crate features UIContextMenuConfiguration and objc2-core-foundation only.

Called when the interaction begins.

Parameter interaction: The UIContextMenuInteraction.

Parameter location: The location of the interaction in its view.

Returns: A UIContextMenuConfiguration describing the menu to be presented. Return nil to prevent the interaction from beginning. Returning an empty configuration causes the interaction to begin then fail with a cancellation effect. You might use this to indicate to users that it’s possible for a menu to be presented from this view, but that there are no actions to present at this particular time.

unsafe fn contextMenuInteraction_configuration_highlightPreviewForItemWithIdentifier( &self, interaction: &UIContextMenuInteraction, configuration: &UIContextMenuConfiguration, identifier: &ProtocolObject<dyn NSCopying>, ) -> Option<Retained<UITargetedPreview>>

where Self: Sized + Message,

Available on crate features UIContextMenuConfiguration and UITargetedPreview only.

Called when a context menu interaction begins. Return a UITargetedPreview corresponding to the item with the given identifier.

Parameter interaction: The UIContextMenuInteraction.

Parameter configuration: Configuration of the menu that will be presented if the interaction proceeds.

Parameter identifier: Identifier for the item whose preview is being requested.

Safety

identifier should be of the correct type.

unsafe fn contextMenuInteraction_configuration_dismissalPreviewForItemWithIdentifier( &self, interaction: &UIContextMenuInteraction, configuration: &UIContextMenuConfiguration, identifier: &ProtocolObject<dyn NSCopying>, ) -> Option<Retained<UITargetedPreview>>

where Self: Sized + Message,

Available on crate features UIContextMenuConfiguration and UITargetedPreview only.

Called when a context menu is dismissed. Return a UITargetedPreview corresponding to the item with the given identifier.

Parameter interaction: The UIContextMenuInteraction.

Parameter configuration: Configuration of the menu being dismissed.

Parameter identifier: Identifier for the item whose preview is being requested.

Safety

identifier should be of the correct type.

fn contextMenuInteraction_willPerformPreviewActionForMenuWithConfiguration_animator( &self, interaction: &UIContextMenuInteraction, configuration: &UIContextMenuConfiguration, animator: &ProtocolObject<dyn UIContextMenuInteractionCommitAnimating>, )

where Self: Sized + Message,

Available on crate feature UIContextMenuConfiguration only.

Called when the interaction is about to “commit” in response to the user tapping the preview.

Parameter interaction: The UIContextMenuInteraction.

Parameter configuration: Configuration of the currently displayed menu.

Parameter animator: Commit animator. Add animations to this object to run them alongside the commit transition.

fn contextMenuInteraction_willDisplayMenuForConfiguration_animator( &self, interaction: &UIContextMenuInteraction, configuration: &UIContextMenuConfiguration, animator: Option<&ProtocolObject<dyn UIContextMenuInteractionAnimating>>, )

where Self: Sized + Message,

Available on crate feature UIContextMenuConfiguration only.

Called when the interaction is about to display a menu.

Parameter interaction: The UIContextMenuInteraction.

Parameter configuration: The configuration of the menu about to be displayed by this interaction.

Parameter animator: Appearance animator. Add animations to run them alongside the appearance transition.

fn contextMenuInteraction_willEndForConfiguration_animator( &self, interaction: &UIContextMenuInteraction, configuration: &UIContextMenuConfiguration, animator: Option<&ProtocolObject<dyn UIContextMenuInteractionAnimating>>, )

where Self: Sized + Message,

Available on crate feature UIContextMenuConfiguration only.

Called when the interaction is about to end.

Parameter interaction: The UIContextMenuInteraction.

Parameter configuration: Ending configuration.

Parameter animator: Disappearance animator. Add animations to run them alongside the disappearance transition.

fn contextMenuInteraction_previewForHighlightingMenuWithConfiguration( &self, interaction: &UIContextMenuInteraction, configuration: &UIContextMenuConfiguration, ) -> Option<Retained<UITargetedPreview>>

where Self: Sized + Message,

👎Deprecated

Available on crate features UIContextMenuConfiguration and UITargetedPreview only.

Called when the interaction begins. Return a UITargetedPreview describing the desired highlight preview.

Parameter interaction: The UIContextMenuInteraction requesting a highlighting preview.

Parameter configuration: The configuration of the menu about to be displayed by this interaction.

fn contextMenuInteraction_previewForDismissingMenuWithConfiguration( &self, interaction: &UIContextMenuInteraction, configuration: &UIContextMenuConfiguration, ) -> Option<Retained<UITargetedPreview>>

where Self: Sized + Message,

👎Deprecated

Available on crate features UIContextMenuConfiguration and UITargetedPreview only.

Called when the interaction is about to dismiss. Return a UITargetedPreview describing the desired dismissal target. The interaction will animate the presented menu to the target. Use this to customize the dismissal animation.

Parameter interaction: The UIContextMenuInteraction requesting a dismissal preview.

Parameter configuration: The configuration of the menu displayed by this interaction.

Returns: Return a UITargetedPreview describing the desired dismissal target. Return nil to cause the menu to animate away without morphing into a specific view.
