# PKResponderState

An object that controls PencilKit behavior associated with a responder.

## Declaration

```swift
class PKResponderState
```

## Overview

Overview 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
