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 is the objective C

- (UIView *)preferredFocusedView
{
    if (someCondition) {
      // this is if your menu is a tableview
        NSIndexPath *ip = [NSIndexPath indexPathForRow:2 inSection:0];
        UITableViewCell * cell = [self.categoryTableView cellForRowAtIndexPath:ip];

        return cell;
    }

    return self.view.preferredFocusedView;

}

in your viewDidLoad or view did appear do something like this:

    UIFocusGuide *focusGuide = [[UIFocusGuide alloc]init];
    focusGuide.preferredFocusedView = [self preferredFocusedView];
    [self.view addLayoutGuide:focusGuide];

if you want to do it when it first launches
