I'm working on Apple TV project. The project contains tab bar view controller, normally the tab bar will be appeared when swiping up on remote and hidden when swiping down. But now I reverse that behavior and I want to force focus another view when swiping up(normally focus on tab bar). Any way to do that? Thank you.
I got the same issue with focus of UITabbarController before and I found the solution in Apple Support
Because UIViewController conforms to UIFocusEnvironment, custom view controllers in your app can override UIFocusEnvironment delegate methods to achieve custom focus behaviors. Custom view controllers can:
Override the preferredFocusedView to specify where focus should start by default. Override shouldUpdateFocusInContext: to define where focus is allowed to move. Override didUpdateFocusInContext:withAnimationCoordinator: to respond to focus updates when they occur and update your app’s internal state. Your view controllers can also request that the focus engine reset focus to the current preferredFocusedView by callingsetNeedsFocusUpdate. Note that calling setNeedsFocusUpdate only has an effect if the view controller contains the currently focused view.
