Passing data between two controllers using storyboards

Question

I am trying to pass data from one UITableViewController to another. This is my code in the initial view controller:

- (void)tableView:(UITableVi         


        

Answer 1

You need to understand that performSegueWithIdentifier:sender: creates a new instance of view controller. So the ListsViewController that you have created is not the being displayed on the screen.

You need to override `prepareForSegue:sender:

- (void)showList:(Subject *)subject animated:(BOOL)animated 
{
  [self performSegueWithIdentifier:@"showDetail" sender:self];
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"showDetail"]) {
        ListsViewController *controller = (ListsViewController *)segue.destinationViewController;
    controller.subject = self.subject;
}
