UIView should catch tap event but pass on moving events

I have two views, one above another as a child. View1--->View2 (View1 has View2 as a child)

How can I code this functionality? 1) if user TAPed on View2 - so the proper message tapped: sent to View2; 2) if user just moving finger over the View1(including View2) - events passed to View1 so it can handle touchesBegan: and so on.

So what I am trying to code is make one function "[View2 tapped:...]" if touch was short, and another function([View1 touchesBegan:..] and so on) if touch is moving.

In my case if I move finger over View2 - it never passes events to View1.

P.s. I did not rewrite hitTest or anything.

Gesture recognizers handle this sort of logic quite elegantly. Have a UITapGestureRecognizer on view2, and do whatever you want on view1 (e.g. a UIPanGestureRecognizer). That takes care of all of the "what gestures are recognized by what views" logic you need.

You should look at UIGestureRecognizers. One of them is UITapGestureRecognizer - catches taps on targeted UIView. It's very simple to use. Look Apple documentation.
