使用push方法后關閉viewController

Question

我使用此功能來推送新的viewController：

func goToPasscodeSetupVC() {
    let storyboard = UIStoryboard(name: "PassCode", bundle: nil)
    let viewController = storyboard.instantiateViewController(withIdentifier: "passcodeSetupVC") as! PasscodeSetupVC
    self.navigationController?.pushViewController(viewController, animated: true)
}

但是，當我使用新的viewController時，我想關閉前一個，以便無法通過滑動手勢到達它。

Answer 1

您可以使用它禁用向后滑動手勢。

self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false

Answer 2

您可以嘗試使用setViewControllers而不是pushViewController

    let storyboard = UIStoryboard(name: "PassCode", bundle: nil)
    let viewController = storyboard.instantiateViewController(withIdentifier: "passcodeSetupVC") as! PasscodeSetupVC
    self.navigationController?.setViewControllers([viewController], animated: true)
