Here is the idea:

I have a NSWindow containing 2 NSView, let’s call them ViewA and ViewB.

ViewA has a list of subview objects, each object has its own tracking area set and handles a mouseDown event. ViewB is a hidden view, which appears above ViewA.

The problem is when ViewB appears, ViewA still receives mouseDown events. So when I click on ViewB, the object behind the ViewB receives the mouseDown event. I would like to know if there’s any way to block the events of ViewA while ViewB is over it.

I know I can remove the tracking area from every object, but it still responds to the mouseDown event.

    you can also disable the touch events for ViewA by [ViewA setAcceptsTouchEvents:NO];
    and can enable them again as per your requirement by setting YES again.
