i have back button and menu button in every view controller, I want to use the default action of back button in each view controller baut i didn't know how, is there any way that solve this problem

Answer 1

    class SuperViewController: UIViewController {
func goBackNavigationBarItem(){
        //Left Button - Navigation bar
        let leftButton = UIBarButtonItem(image: UIImage(named: imgName)?.withRenderingMode(.alwaysOriginal), style: .plain, target: self, action: #selector(SuperViewController.btnBackClicked(_:)))

        self.navigationItem.leftBarButtonItem = leftButton;
    }

func btnBackClicked(_ sender:UIButton!){
    // whatever action You want on back button 
}
}

make your viewController child of SuperViewController and Call this function goBackNavigationBarItem() in viewDidLoad() of every view controller Like this..

class AnyVC: SuperViewController{

override func viewDidLoad() {
        super.viewDidLoad()
        goBackNavigationBarItem()
    }
}

Hope this help.
