The collection view object requesting this information.
The index path of an item in the collection view.
true if the item can receive be focused or
false if it can not.
You can use this method, or a cell’s
can method, to control which items in the collection view can receive focus. The focus engine calls the cell’s
can method first, the default implementation of which defers to the collection view and this delegate method.
If you do not implement this method, the ability to focus on items depends on whether the collection view’s items are selectable. When the items are selectable, they can also be focused as if this method had returned
true; otherwise, they do not receive focus.
