Available on crate feature UISpringLoadedInteraction only.

UISpringLoadedContext supplies information about the springloading state and current drag.

Provided Methods

unsafe fn state(&self) -> UISpringLoadedInteractionEffectState

where Self: Sized + Message,

The state that describes the current springloading style.

unsafe fn targetView(&self) -> Option<Retained<UIView>>

where Self: Sized + Message,

Available on crate features UIResponder and UIView only.

The view to which the interaction effect is applied. Defaults to the interaction’s view.

unsafe fn setTargetView(&self, target_view: Option<&UIView>)

where Self: Sized + Message,

Available on crate features UIResponder and UIView only.

Setter for targetView.

unsafe fn targetItem(&self) -> Option<Retained<AnyObject>>

where Self: Sized + Message,

The targetItem allows to distinguish a region of the view on which the interaction is installed. It is convenient to set this property to a model object associated to targetView.

unsafe fn setTargetItem(&self, target_item: Option<&AnyObject>)

where Self: Sized + Message,

Setter for targetItem.

unsafe fn locationInView(&self, view: Option<&UIView>) -> CGPoint

where Self: Sized + Message,

Available on crate features UIResponder and UIView and objc2-core-foundation only.

Returns the point computed as the location of the current drag in a given view.

Parameter view: A view on which the drag is taking place. Specify nil to indicate the window.

Returns: A point in the local coordinate system of view.
