          self.navigationController.view.layer.shadowColor = [UIColor blackColor].CGColor;
          self.navigationController.view.layer.shadowOffset = CGSizeMake(3, 0);  /*Change value of X n Y as per your need of shadow to appear to like right bottom or left bottom or so on*/
          self.navigationController.view.layer.shadowOpacity = 0.5f;
