preferredFocusEnvironments → NSArray

Available on UIViewController, provided by the UIViewController$Methods extension

The preferred focus environments define where to search for the default focused item in an environment, such as when focus updates programmatically. Starting from the target environment, each preferred focus environment is recursively searched in the order of the array until an eligible, focusable item is found. Preferred focus environments can include focusable and non-focusable items, in addition to non-item environments. Returning an empty array is equivalent to returning an array containing only 'self'.
