How can I force focus to change to a specific view in tvOS?

Question

I am implementing custom code to handle a click on the Menu button on the Siri Remote. How can I force focus to change to my custom menu when pressing the menu button?

Answer 1

Here's a nice little Swift 2 copy / paste snippet:

var myPreferredFocusedView: UIView?
override var preferredFocusedView: UIView? {
    return myPreferredFocusedView
}
func updateFocus(to view: UIView) {
    myPreferredFocusedView = napDoneView
    setNeedsFocusUpdate()
    updateFocusIfNeeded()
}

Use it like this:

updateFocus(to: someAwesomeView)
