터지하면 status bar (상태바), navigation bar (네비게이션바) 숨겼다 보였다 하기

탭(터치)하면 보였다가 다시한번하면 안보이게 하는 소스~

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event

{

    NSLog(@"OK");

    if ([UIApplication sharedApplication].isStatusBarHidden)

    {

        [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation: UIStatusBarAnimationFade];

        self.navigationController.navigationBarHidden = NO;

    }

    else

    {

        [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation: UIStatusBarAnimationFade];

        self.navigationController.navigationBarHidden = YES ;

    }

}
