Aplication run different after a delete from background on Device
===

     I'm working on an application and when you load the device and run it behaves normally.
     How long remains open in the background works fine (I mean when you close it and reopen - without a background removed).
     When you delete an application in background and open, it "loses" the functionality.
     For example I have a scroll containing a screen populated with more "cells" and when you touchupdown behave exactly as if the icons on the devices from Apple (shaking and you can move / delete) .
      After I deleted the application of background only a single "cell shaking" and perhaps moved.
       Can someone help me with some advice? Is there any method to be implemented like "applicationWillEnterForeground" in case the application is reopened in a situation similar to reopen in the background.
      Thanks in advance!
