Question

我使用此函数来推送一个新的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，当我使用新的viewController时，我想要忽略前一个，以便我无法通过轻扫手势触及它。

Answer 1

您可以使用它来禁用滑动后退手势。

self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false

Answer 2

您可以尝试使用setViewControllers代替pushViewController

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

使用push方法后关闭viewController
