nit: Change this line to

   ... = NSHeight(viewFrame) - NSMaxY(rect);

and delete the next line while you're here?

Done.

   rect.origin.y -= rect.size.height;
-  rect = [self convertRectToBase:rect];
+  rect = [self convertRect:rect toView:nil];
   rect.origin = [[self window] convertBaseToScreen:rect.origin];
   return rect;
