mouse over on image object which was drawn on view

I have dr开发者_如何转开发awn an object on NSView subclass. How can the object know that mouse over is done

on it when mouse passes over it.


If the object is neither NSView nor CALayer (that is, you draw it in your view's drawRect:), the recommended way is to use NSTrackingArea class. You will get the notifications you need sent to the NSView.
