title: Prevent iOS app from keeping screen snapshot using Cordova
body: <p>I'm working on cordova/ng4 ios application which contains personal data of users and I don't want old snapshot to be displayed when going back to application from multitasking or re-opening the application. Is it possible to set some kind of property in <code>.plist</code> file that will block keeping the snapshot?
  P.S. I also use <code>UIApplicationExitsOnSuspend</code> property which prevents application from running in the background.</p>
