There are many ways to do something like this.

  • ViewWillDisappear implementation
  • ViewWillAppear implementation
  • Set up a delegate for your navigation and respond to changes.
  • Make your own feedback button that links to your own function.
  • Use NSNotification when moving

Any of the above is a good starting place.
