[Solved] How could I use touchesBeganWithEvent in iOS?

[Wei]

Hi

I'm creating a module that allow user to draw in the canvas. can someone tell me how I can implement

touchesBeganWithEvent(touches: NSSet, event: UIEvent): void;
touchesMovedWithEvent(touches: NSSet, event: UIEvent): void;
touchesEndedWithEvent(touches: NSSet, event: UIEvent): void;

with Javascript in ui modules?

I have figured out by myself
