        [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
    }
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
}

- (BOOL)prefersStatusBarHidden {
    return YES;
}

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    [self hideStatusBar];
    double delayInSeconds = 0.2;
    dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
    dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
        [self hideStatusBar];
    });
}
