When the user taps the Globe or a custom “next keyboard” key, the system picks the appropriate “next” keyboard from the list of user-enabled keyboards. To determine whether your custom keyboard needs to display a “next keyboard” key, check the
needs property. If the value of the property is
YES, your keyboard should include this key.
