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

I've found something better:

-(void)didUpdateFocusInContext:(UIFocusUpdateContext *)context withAnimationCoordinator:(UIFocusAnimationCoordinator *)coordinator {
    [coordinator addCoordinatedAnimations:^{
        if (self.focused) {
            self.backgroundColor = [UIColor whiteColor];
        }
        else {
            self.backgroundColor = [UIColor clearColor];
        }
    } completion:nil];
}
