Multiple Views in iPad

Trying to open a second detail view from a detail view controller in a split view controller.

Not even having any luck amending Apple's MultipleDetailViews sample project.

-(IBAction)subViewButtonClicked
{
    UIViewController <Sub开发者_开发百科stitutableDetailViewController> *detailViewController = nil;

    SubDetailViewController *subDetailViewContoller = [[SubDetailViewController alloc] initWithNibName:@"SubDetailViewController" bundle:nil];
    detailViewController = subDetailViewContoller;

    // Update the split view controller's view controllers array.
    NSArray *viewControllers = [[NSArray alloc] initWithObjects:self.navigationController, detailViewController, nil];
    splitViewController.viewControllers = viewControllers;

    [viewControllers release];   
}

Any help appreciated.

The example project allowed the reuse of xibs and views to fix my issue perfectly.
