- (IBAction)searchOptions:(id)sender {
    FilterViewController *ctrl = [[FilterViewController alloc] init];
    [UIView transitionFromView:self.view toView:ctrl.view duration:1 
          options:UIViewAnimationOptionTransitionCurlUp completion:nil];

    self.filterViewController = ctrl;

    [self.navigationController pushViewController:self.filterViewController 
          animated:NO];
}

- (IBAction)backToMap:(id)sender {

    // i used the below when trying to push another view controller
    /*UIStoryboard *storyboard = [UIStoryboard storyboardWithName
        :@"MainStoryboard" bundle:nil];

    FirstViewController *fvc = [storyboard 
        instantiateViewControllerWithIdentifier:@"FirstViewController"];

    fvc.modalTransitionStyle = UIModalTransitionStyleCoverVertical;*/
