How to retain my nsstring when popping to another view controller

Question

I am trying make an NSString retain its value in another view controller, and it works when I push to the viewcontroller controller. However when I use the apple's navigation back button (automatically generated) it doesn't retain the value. How do I overcome this? I believe the automatic back button is poptoviewcontroller. I will post some code to help give you an idea.

NSString *ee = @"energy";
optViewController.energy = ee;

Controller I am trying to goto.

 @property (strong,nonatomic) NSString *energy

The view controller will get released if you don't keep a reference to it. — msgambel, Aug 31 '13 at 20:42
