如何在UIViewController中禁用拖动关闭

Question

I have UIViewController add to my view by present. Now user can remove this view by drag to bottom of screen. How can I disable it?

I try by

view.isUserInteractionEnabled = false

and

override func viewDidLoad() {
        self.transitioningDelegate = self
    }

extension MyViewController: UIViewControllerTransitioningDelegate {
    func interactionControllerForDismissal(using animator: UIViewControllerAnimatedTransitioning) -> UIViewControllerInteractiveTransitioning? {
        return nil
    }

    func animationController(forDismissed dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        return nil
    }
}

But user still can dismiss it.

Answer 1

您需要禁用平移手势才能禁用拖动关闭。

Answer 2

You can use this line in the viewController's viewDidLoad method:

self.navigationController.interactivePopGestureRecognizer.enabled = NO;

You can refer this .

.isModalInPresentation = true worked for me
