Requirements

zIndex

Tool's interaction view z-Index in superview. The higher the value, the top the view.

var zIndex: Int 

strategy

Tool's interaction view response strategy.

var strategy: ADInteractStrategy 

interactClipBounds

Whether interaction view clip to clip rect bounds when interacting.

var interactClipBounds: Bool 

clipingScreenInfo

Interaction view clip info use to congfig .

var clipingScreenInfo: ADClipingInfo? 

shouldInteract(_:​point:​)

Check if view can interact with gesture.

func shouldInteract(_ gesture: UIGestureRecognizer, point: CGPoint) -> Bool

Parameters

• gesture: User interaction gesture.
• point: Gesture location in view.

Returns

Return true if view can response user's interaction. Otherwise, return false.

interact(with:​scale:​state:​)

Do some action with user interaction.

func interact(with type: ADInteractType, scale: CGFloat, state: UIGestureRecognizer.State) -> TimeInterval?

Parameters

• type: Interaction gesture type.
• scale: Interaction view's scale to orgin image size.
• state: Interaction gesture state.

Returns

Return delay time of interaction view become clip when interactClipBounds is false. Return nil or 0 means no delay.

willBeginRenderImage()

Called before render view to image.

func willBeginRenderImage()

didEndRenderImage()

Called after render view to image.

func didEndRenderImage()
