Answer 1

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;
}
