Hide/show status bar on sidebar opening (SWRevealViewController)

Hide status bar on sidebar opening

- (void)revealController:(SWRevealViewController *)revealController willMoveToPosition:(FrontViewPosition)position 
{
    if (position == FrontViewPositionRight) {
        UIApplication *sharedApplication = [UIApplication sharedApplication];
        CGFloat statusBarHeight = CGRectGetHeight([sharedApplication statusBarFrame]);

        [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
        UINavigationController *frontViewController = (id)revealController.frontViewController;

        CGPoint center = frontViewController.navigationBar.center;
        center.y += statusBarHeight;
        frontViewController.navigationBar.center = center;

        UIViewController *topViewController = frontViewController.topViewController;
        topViewController.view.frame = CGRectOffset(topViewController.view.frame, 0, statusBarHeight);
    }
    else {
        [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade];
    }
}

Pardon my ignorance, but which file would you add this in? Specifically, which view controller? Thanks

The class that implements the SWRevealViewControllerDelegate protocol.
