How can I create a button with a background color for tvOS while still showing focus?

Question

All I want to do is add a background color to a button for all states. But I want to maintain the automatic focus shadow that you get \"for free\" when using a system button

Answer 1

You can add a shadow for your custom button like this:

- (void)didUpdateFocusInContext:(UIFocusUpdateContext *)context withAnimationCoordinator:(UIFocusAnimationCoordinator *)coordinator
{
    context.nextFocusedView.layer.shadowOffset = CGSizeMake(0, 10);
    context.nextFocusedView.layer.shadowOpacity = 0.6;
    context.nextFocusedView.layer.shadowRadius = 15;
    context.nextFocusedView.layer.shadowColor = [UIColor blackColor].CGColor;
    context.previouslyFocusedView.layer.shadowOpacity = 0;
}
