However I dont want to see the navigation bar on the top for the first view. Is there a way for adding the navigation controller to appdelagete and make the navigation bar not visible for my first screen.

Answer 1

To add navigation bar in your app

Use following code in didFinishedLaunching:withOptions: of AppDelegate class:

ViewController *homeController = [[HomeController alloc] init];
self.controller = [[UINavigationController alloc] initWithRootViewController:viewController];
[self.window addSubview:self.controller.view];
[self.window makeKeyAndVisible];

In the ViewController's viewWillAppear method, Add the following line of code:

[[self navigationController] setNavigationBarHidden:YES animated:NO];

In the ViewController's viewWillDisappear method, Add the following line of code:

[[self navigationController] setNavigationBarHidden:NO animated:NO];

Answer 2

Put this below code in your viewWillAppear method to get it called everytime when you return on the first view

[self.navigationController setNavigationBarHidden:YES animated:NO];

and put

[self.navigationController setNavigationBarHidden:NO animated:NO];

in viewDidLoad of next controller you want to push or, you can also place the above code in viewWillDisappear of FirstViewController.
