How to catch multi-touch event in NSView

Question

Dear all,

Is there any way to handle multi-touch in a class which extend NSView? currently 1 touch with drag event is working now.

Answer 1

Actually, I am developing a feature which draw a chart and I used Core-Plot charting library, but the CPLayerHosting is extended from NSView so I don't know how to catch more than one touch points.

Very lucky for me that there are 2 CPLayerHosting class in Core-Plot project, another one is just used for IPhone and it is extended from UIView, so the problem is resolved! :)
