swift 返回指定界面的几种方法

// 跳转指定控制器
    func jumpDesignatedController() {
        
        // 方法一(跳转指定控制器)
        let mineVC = MyAcountAuthViewController()
        var targetVC : UIViewController!
        for controller in self.navigationController!.viewControllers {
            if controller.isKind(of: mineVC.classForCoder) {
                targetVC = controller
            }
        }
        if targetVC != nil {
            self.navigationController?.popToViewController(targetVC, animated: true)
        }
        
        // 方法二(跳转根控制器)
        self.navigationController?.popToRootViewController(animated: true)
        
        // 方法三(返回到根界面的某个控制器)
        self.navigationController?.tabBarController?.hidesBottomBarWhenPushed = false
        self.navigationController?.tabBarController?.selectedIndex = 0 // (第一个控制器)
        self.navigationController?.popToRootViewController(animated: true)
        // 方法四(返回两级界面)
        if (self.navigationController?.viewControllers.count)! >= 2 {
            guard let vc = self.navigationController?.viewControllers[1] else { return }
            self.navigationController?.popToViewController(vc, animated: true)
        }
    }
