ViewController's private data set to nil after returning from segue

Vote count:

I have two views. The main view is ViewController and the next is AddItemViewController. ViewController has a tableview that lists items that you add when you go to AddItemViewController. There is a button on AddItemViewController that segues back to ViewController. The problem is, upon returning to ViewController expecting that an item be added, the private data of ViewController is suddenly set to nil. I have lost data and any chance to interact with my objects after returning from the segue.

Here is the data that's getting set to nil

@property (strong, nonatomic) costEstimator *myCost;
@property NSString *testString;

What am I doing wrong?

Here is my prepareforsegue code in the AddItemViewController

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
// Get the new view controller using [segue destinationViewController].
ViewController *vC = [segue destinationViewController];
[vC addSomething:_selectedItem withQuantity:[_quantBox.text doubleValue]];
}

Any help is greatly appreciated. Thanks :)
