INavigationController *a = (UINavigationController *)self.tabBarController.selectedViewController;
Second11ViewController *view11 = [[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateViewControllerWithIdentifier:@"second1"];
Second22ViewController *view22 = [[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateViewControllerWithIdentifier:@"second2"];
view11.hidesBottomBarWhenPushed = YES;
view22.hidesBottomBarWhenPushed = YES;
