Swipe back function in IOS App

Question

I am working on an application in Xamarin. The iOS feature of swipe back is not working and I don't know how to figure it out and fix it. Any kind of help will be appreciated. Where can I find this feature in my app code files and. how to enable or disable it?

Answer 1

self.navigationController.interactivePopGestureRecognizer.delegate = nil;

Answer 2

You can create a UIGestureRecognizerDelegate , in this Delegate we can use an event called ShouldBegin() to enable or disable the system back feature:

public class MyGestureDelegate : UIGestureRecognizerDelegate
{
    public override bool ShouldBegin(UIGestureRecognizer recognizer)
    {
        return true;
    }
}

Then assign the Delegate to it:

NavigationController.InteractivePopGestureRecognizer.Delegate = new MyGestureDelegate();
