Dismiss a viewController after using a push method

Question

I use this function to push a new viewController:

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

But, when I am on the new viewController, I want to dismiss the previous one so that I could't reach it with a swipe gesture.

Answer 1

您可以使用它禁用向后滑动手势。

self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false

Answer 2

You can try setViewControllers instead of pushViewController

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