In appDelegate.h

@property (strong, nonatomic) UINavigationController *navController;

and set the delegate UINavigationControllerDelegate and synthesise object in appDelegate.m now,

appDelegate.m

you can set navigation controller in didFinishLaunchingWithOptions method

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    frstVwCntlr = [[firstViewController alloc] initWithNibName:@"firstViewController" bundle:nil];
    self.navController = [[UINavigationController alloc] initWithRootViewController:self.frstVwCntlr];
    self.window.rootViewController = self.navController;
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];
    return YES;
}

In the above code , your firstViewController is set to UINavigationController and UINavigationController added to UIWindow like

self.window.rootViewController = self.navController

Hope this may help you

If you want to create everything programmatically you have to do it in AppDelegate.

But if you don't want to do it programmatically, then just select the ViewController in Storyboard then select menu options:

You can creat UINavigationController in Appdelegate and set your first viewcontroller on it.

So for creating a UINavigationController programatically without using storyboards, go to your app delegate and do the following. Create two properties, window and viewController

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.backgroundColor=[UIColor clearColor];

    self.viewController = [[YourFirstViewController alloc] initWithNibName:@"YourFirstViewController" bundle:nil];
    UINavigationController *navController=[[UINavigationController alloc]initWithRootViewController:self.viewController];
    self.window.rootViewController = navController;
    [self.window makeKeyAndVisible];

    // Override point for customization after application launch.
    return YES;
}

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
ImageViewController2 *dealVC = (ImageViewController2 *)[storyboard instantiateViewControllerWithIdentifier:@"ImageViewController2"];
[self.navigationController pushViewController:dealVC animated:YES];

where ImageViewController2 is a class name

Here is the code that you should write in app delegate.

UIViewController *vc=[[UIViewController alloc]initWithNibName:@"vc1" bundle:nil];
UIView *view=[[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 568)];
view.backgroundColor=[UIColor redColor];
[vc setView:view];

self.navme=[[UINavigationController alloc]initWithRootViewController:vc];
self.window.rootViewController = self.navme;

For Swift 3.0, using filter:

let desiredController = self.navigationController!.viewControllers.filter { $0 is YourController }.first!
self.navigationController!.popToViewController(desiredController, animated: true)
