You can also use the -(void)prepareForSegue:... - Method to share data between controllers.

For Example:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{

   if ([segue.identifier isEqualToString:@"Your_Identifier"]) {

     TestViewController *controller = [segue destinationViewController];

     NSArray *array = [[NSArray alloc] initWithObjects:@"",nil];

     controller.objectInTestViewController = array;

   }
}

Hope this helps someone....

-(IBAction)button3Clicked:(id)sender
{
  QuizModalViewController *mvid=[[QuizModalViewController alloc]initWithNibName:@"QuizModalViewController" bundle:nil];
mvid.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
mvid.theDataYouWantToPass = theData; // this is how you do it
[self presentModalViewController:mvid animated:YES];
}

Note that theDataYouWantToPass must be a property declared in the QuizModalViewController.h file.

Make your QuizModalViewController available at class scope instead of using a local variable. Then in the goBackToView: you can access the controller's content prior to dismissing it.

By the way: in your code you're leaking mvid. Release it after presenting it modally.
