Hey, in iOS there is a NavBar native widget. This can have a back button on it, which if pressed, pops the current screen off the stack screen and shows the old screen. My problem is that I don't get any event if this happens. If I need to update my screen again before it is shown, then I don't have an event to capture or a method call I can use to know that my screen is going to be shown.
With Android, if the user presses the back button on the handset, then a keyPressEvent is triggered, but I con't find an equivalent method on iOS.
Is it hard?
