PKResponderState
An object that controls PencilKit behavior associated with a responder.
Declaration
class PKResponderStateOverview
Access a responder’s PKResponderState through the pencilKitResponderState property on any UIResponder. Use it to attach a tool picker to a specific view and control when that picker is visible. Tool picker visibility follows the responder chain: if a responder’s visibility is set to PKToolPickerVisibilityInherited, it defers to the next responder in the chain. If no responder in the chain specifies a visibility, the tool picker defaults to visible.
view.pencilKitResponderState.activeToolPicker = PKToolPicker()
view.pencilKitResponderState.toolPickerVisibility = .visible
