How to disable the scrolling and dragging/zooming of UIScrollView when using SwiftyDraw inside it?

Hi, thank you for providing this excellent library. I encountered a problem while using it: how can I disable the drag and zoom events of UIScrollView when adding a subview SwitfyDraw to it and drawing while scrolling?
I am new to UIKit, so the problem I described is a bit vague. Thank you for your help.
