Disable InteractivePopGestureRecognizer for specific page

[Divyesh-Bhatt]

Description

In iOS 15 and above we can perform back navigation using swipe (from left edge of the device). I've noticed that on initial page which is not of type of navigation page if we perform this swipe the app is getting crash in iOS.

To fix this I've found this work around https://learn.microsoft.com/en-us/answers/questions/306452/disable-xamarin-shell-flyout-swipe-gesture

But this disables the swipe for entire app, which is not intended. So how to make it page specific?

Intended Use-Case

Disable Swipe back gesture for iOS when needed for specific page.

To disable the swipe back gesture for iOS on a specific page, you can try the following approach. Hope it helps !

public TestPage( )
{
    InitializeComponent();
    this.Loaded += TestPage_Loaded;
}

private void TestPage_Loaded(object? sender, EventArgs e)
{
#if IOS
    if (Handler is IPlatformViewHandler platformViewHandler)
    {
        var controller = platformViewHandler.ViewController?.NavigationController;
        if (platformViewHandler.ViewController?.NavigationController != null)
        {
            platformViewHandler.ViewController.NavigationController.InteractivePopGestureRecognizer.Enabled = false;
        }
    }
#endif
}

protected override void OnDisappearing()
{
    base.OnDisappearing();
    this.Loaded -= TestPage_Loaded;
}

        }
    }
#endif
}

protected override void OnDisappearing()
{
    base.OnDisappearing();
    this.Loaded -= TestPage_Loaded;
}

Works like a charm,thanks!

I thought have to go through https://learn.microsoft.com/en-us/answers/questions/1143556/how-to-disable-the-swipe-back-in-ios-using-net-mau with Shell , saving much efforts !

Plus might have to mark as ... InteractivePopGestureRecognizer.Enabled = True; in OnDisappearing() as well, if anyone keen on making rest navigation pages swipeable?

Yes, I just tested it and you do need to enable it in the OnDisappearing() method.

Here is a method that allows you to keep all your iOS code in your iOS project:

Microsoft.Maui.Handlers.PageHandler.Mapper.PrependToMapping("MyApp.MyPageHandler", (handler, view) =>
{
    if (view is MyPage page)
    {
        var navigationController = handler?.PlatformView.GetNavigationController();
        if (navigationController != null)
          navigationController.InteractivePopGestureRecognizer.Enabled = false;
    }
});

Trying this with a basic test app of a main page and a second page, inside a navigationpage. The navigationController is never not null. Do you know if something changed since then?

For anyone running into this on iOS 26, Apple added a property named InteractiveContentPopGestureRecognizer which is what you need to disable when running on iOS 26.
You still need to disable InteractivePopGestureRecognizer for earlier versions of iOS and make sure you do not attempt to set InteractiveContentPopGestureRecognizer on iOS < iOS 26 or you will crash.

if (DeviceInfo.Current.Version.Major >= 26)
{
    uiNavigationController.InteractiveContentPopGestureRecognizer.Enabled = false;
}
else
{
    uiNavigationController.InteractivePopGestureRecognizer.Enabled = false;
}
