防止 ViewController 移回上一个

Question

我有一个带有两个视图控制器 (UIViewController) 的简单示例 iOS 应用程序，如下所示。

//HomeViewController
import UIKit

class HomeViewController: UIViewController {
    // MARK: - IBAction
    @IBAction func goSecondTapped(_ sender: UIButton) {
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        if let controller = storyboard.instantiateViewController(withIdentifier: "SecondNavigator") as? UINavigationController {
            if let viewController = controller.topViewController as? SecondViewController {
                self.navigationController?.pushViewController(viewController, animated: true)
            }
        }
    }
    
    
    // MARK: - Life cycle
    override func viewDidLoad() {
       super.viewDidLoad()
    }
}

//SecondViewController
import UIKit

class SecondViewController: UIViewController {
    // MARK: - Life cycle
    override func viewDidLoad() {
       super.viewDidLoad()
    }
}

所以我只想在点击按钮（转到第二个）时切换到 SecondViewController。问题是，如果我只是用手指从左向右滑动第二个视图，我就可以在不点击左上角的“后退”按钮的情况下返回到 HomeViewController。有什么办法可以防止这种情况发生吗？我只想在点击返回时返回 HomeViewController。谢谢

您是否尝试过禁用 interactivePopGestureRecognizer？

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    navigationController?.interactivePopGestureRecognizer?.isEnabled = false
}
