how to find a object in rect or at point

On a NSView there are many other NSViews and some of them are moving with keyboard scroll keys. when moving object come on top of any static one i want to get which object sits under moving one. with mouse this is easy however without mouse i couldn't find a way to achieve this.


You'll need to loop through all of the views you want to test, get each view's frame, convert that rectangle to the relevant view's coordinate system (search for “convertRect:” in the NSView docs), and then use the geometry functions to test whether the moving view's converted frame intersects the static view's frame.
