In particular scenarios, when the user hits the back button to navigate back to the previous page, I want to update that page before it is displayed. On Windows, WinPhone and Android this works fine, but on iOS a cached image of the page is displayed briefly before being overwritten with my updated page. Is there any way to prevent that cached image from appearing?
At the moment, I am doing the update of the page in OnAppearing().
Does the cached image appear briefly even if the Navigation stack is manipulated (inserting a new, updated, instance of the page and removing the old one)? Or is there an easier way of avoiding the cached image appearing?
Many thanks,
John H.
