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?

Finally figured it out myself. You have to override the preferredFocusedView property of your UIView or UIViewController.

In Swift it works like this:

func myClickHandler() {
    someCondition = true
    self.setNeedsFocusUpdate()
    self.updateFocusIfNeeded()
    someCondition = false
}

override weak var preferredFocusedView: UIView? {
    if someCondition {
        return theViewYouWant
    } else {
        return defaultView
    }
}

I can't quite remember how to override getters in Objective-C so if someone want to post that I'll edit the answer.
