Creating manual segue correctly through storyboard and xcode

Question

I\'m quite new to xcode, and I am trying to develop a sample app that is basically an embedded tableview which has many levels. I have a plist which stores the cells of each

THE MAIN ISSUE IS HERE, you were creating a blank DrillDownViewController, not reusing the one from storyboards, see comments in code below

    -(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
    {
        if([[segue identifier] isEqualToString:@"segue1"])
        {
             [segue.destinationViewController setItemName:(NSString*)sender];
        }
    }

    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
    {
        //Check the dictionary to see what cell was clicked
       NSDictionary *dict = [self.tableDataSource objectAtIndex:indexPath.row];
NSString *titleName = [dict objectForKey:@"Title"];
NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row];

NSArray *children = [dictionary objectForKey:@"Children"];

if([children count] == 0)
{
    [self performSegueWithIdentifier:@"segue1" sender:titleName];

}
        else{
    //Prepare to tableview.

    //THE MAIN ISSUE IS HERE, you were creating a blank DrillDownViewController, not reusing the one from storyboards so it did not have a segue at all defined. instead do this:
    UIStoryboard*  sb = [UIStoryboard storyboardWithName:@"MainStoryboard"
                                                  bundle:nil];
    DrillDownViewController *rvController = [sb instantiateViewControllerWithIdentifier:@"DDVC"];       
    //Increment the Current View
    rvController.CurrentLevel += 1;

    //Set the title;
    rvController.CurrentTitle = [dictionary objectForKey:@"Title"];

    //Push the new table view on the stack
    [self.navigationController pushViewController:rvController animated:YES];

    rvController.tableDataSource = children;

}
