Master Detail Application not loading UIViewControllers

I am creating an iPad version of Master Detail Application using XCode 4.5 with ARC. I have my iPadMaster.h/.m(as my master) and iPadDetailViewController.h/m(as my detail) set up.

I am trying to load different view controllers from iPadDetailViewController when users click/select the rows on iPadMaster.

On iPadDetailController.h, i set this:

@property int itemNumber;

On iPadMaster.h, i called it as:

@class iPadDetailViewController;

and proceeded with this:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    DetailViewController * DVC = [[DetailViewController alloc]init];
    DVC.itemNumber = indexPath.row;
}

On iPadDetailViewController, i set this:

- (void)configureView
{
    switch (_itemNumber) {
        case 1:
        {
            iPadLogin *next = [[iPadLogin alloc] init];
            NSMutableArray *mut = [[NSMutableArray alloc]init];
            mut = [self.splitViewController.viewControllers mutableCopy];
            [mut replaceObjectAtIndex:1 withObject:next];
            self.splitViewController.viewControllers = mut;
            break;
        }

        default:{
            self.view.backgroundColor = [UIColor whiteColor];
        }
            break;
    }
}

//then i called it on:
- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    [self configureView];

}

When i clicked the second row in the master table, item_number should be 1 and load the 'iPadLogin' but nothing happens... Any pointers is much appreciated...

Thanx in advance...

As I said in my comment, I think you should change the detail controller from the master controller. It is in the master that you're making the decision on what detail controller to go to (by picking a row in the table), so it should be the responsibility of the master controller to make the change. The code below should do that (note, however, if you're using a storyboard for your controllers, then you should be using [self.storyboard instantiateViewControllerWithIdentifier:@"whatever"] to get your next controller rather than alloc init). 

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
    {
        switch (indexPath.row) {
            case 1:
            {
                iPadLogin *next = [[iPadLogin alloc] init];
                NSMutableArray *mut = [[NSMutableArray alloc]init];
                mut = [self.splitViewController.viewControllers mutableCopy];
                [mut replaceObjectAtIndex:1 withObject:next];
                self.splitViewController.viewControllers = mut;
                break;
            }
            case 2:
            {
                AnotherVC *another = [[AnotherVC alloc] init];
                NSMutableArray *mut = [[NSMutableArray alloc]init];
                mut = [self.splitViewController.viewControllers mutableCopy];
                [mut replaceObjectAtIndex:1 withObject:another];
                self.splitViewController.viewControllers = mut;
                break;
            }

            default:{
                UIViewController *detail = self.splitViewController.viewControllers[1];
                detail.view.backgroundColor = [UIColor whiteColor];
            }
                break;
        }
    }
