Even when an object that conforms to
UIFocus is not currently focusable, it may still have an effect on the focus system. For example, items that are not focusable, but that completely obscure other items, may prevent those other items from being focusable, because they are not visible to the user. Also, because
UIFocus conforms to
UIFocus, items that are not focusable may still affect the focus behavior of items they contain, or react to focus updates.
