Answer 1

Here is the answer from Pfitz, but I made it a little easier to understand for folks who are new to Objective-C using an example:

1. In your destinationViewController.h file add property setting for variable to 'receive' value from your source controller.m file

   @property (nonatomic) int billIdReceivingVote;
   

2. Import your destinationViewController.h to your sourceViewController.m file:

   // VOLViewController.m
   #import "VOLVoteViewController.h
   

3. Add prepareForSegue method to your sourceViewController.m file and pass the variables

   - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
   {
       VOLVoteViewController *myDestinationViewController = [segue destinationViewController];
   
       // myDestinationViewController.variable = sourceViewController variabe
       myDestinationViewController.billIdReceivingVote = [self.idOfBillSelected intValue];
   }
