Xojo uses all native controls for iOS, so switch control should ājust workā. I havenāt tried it, but I canāt think of anything that would cause an issue. If you created a custom control using an iOSCanvas, you would have to implement the protocol yourself, but even an iOSUserControl based item should work natively if it is using a UIKit class.
If you need to get the notification that you linked to, you might look at iOSKit or iOSLib. If itās not there, it would be fairly simple to put together (with a handful of declares)ā¦
