How to add splitViewController

Question

In my app(a sample app, upon success, gonna implement in my app) i am moving to viewController from my Appdelegate. In my ViewController.m, i am initialising a SplitViewController. But my code is not working.. I have given my appDelegate and ViewController codes..

Appdelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.

self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil]; 
self.navigationController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
self.window.rootViewController = self.navigationController;
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}

ViewController.m

- (void)viewDidLoad
{


[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
}

-(IBAction)btnClick:(id)sender
{
PopMenuViewController *menuVC = [[PopMenuViewController alloc] initWithStyle:UITableViewStylePlain];
UINavigationController *menuNavController = [[UINavigationController alloc] initWithRootViewController:menuVC];

PopMenuDetailViewController *detailVC = [[PopMenuDetailViewController alloc] initWithNibName:@"PopMenuDetailViewController" bundle:nil];
UINavigationController *detailNavController = [[UINavigationController alloc] initWithRootViewController:detailVC];

menuVC.detailViewController = detailVC;

splitViewController = [[UISplitViewController alloc] init];
splitViewController.viewControllers = @[menuNavController, detailNavController];

 //appdelegate.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
 //appdelegate.window.rootViewController = self.splitViewController;

[appdelegate.window addSubview:self.splitViewController.view];
}

Am not giving this code in AppDelegate because, in my real app, i need to implement splitviewcontroller concept only in my contacts page.. so i need to get splitViewController working when i click CONTACT button from my HOMEPAGE.. So can anyone help me with this?

Answer 1

SplitViewController should be at the root of the application. Instead of making NavigationController root view controller of the application , you should make SplitViewController its root.

My suggestion :
1. Learn more about SplitViewController. Check here.
2. Learn more about ViewControllers. Check this Programming Guide.
