Can I cancel touch programmatically?

UIScrollView has a canceling mechanism, where it cancels the touch of subviews when it detects 'scrolling'.

I wonder if I can cancel a touch event (which already has begun) programmatically.

I have a draggable view inside a scroll view.
I can let the draggable view receive touches, but I'm wondering how to stop receiving touch events when I want and give touch events to the scroll view.

Have a look at cancelTrackingWithEvent:

Well I have had a similar problem.

I have solved it by disabling the scroll view when you receive touch event on its subview.

And when you think your event is complete you re-enable the scroll view.

If you do not do enable-disable the scroll view cancels your drag events automatically!
