Hide UINavigationItem in IOS

Question

The code I wrote was working fine until I brought about a BannerView to show ads in the app. To bring the BannerView in all views I used the following code in AppDelegate's didFinishLaunchingWithOptions:

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

        UIStoryboard*  sb = [UIStoryboard storyboardWithName:@"Main_iPhone" bundle:nil];
        self.viewController = [sb instantiateViewControllerWithIdentifier:@"ViewController"];

    } else {

        UIStoryboard*  sb = [UIStoryboard storyboardWithName:@"Main_iPad" bundle:nil];
        self.viewController = [sb instantiateViewControllerWithIdentifier:@"IpadViewController"];

    }
    self.navigationController=[[UINavigationController alloc]initWithRootViewController:self.viewController];
    self.bannerViewController = [[BannerViewController alloc] initWithContentViewController:self.navigationController];
    self.window.rootViewController = self.bannerViewController;
    [self.window makeKeyAndVisible];

    return YES;
}

But when I used this code a UINavigationItem appears on the top, hiding my actual controls. I want to hide UINavigationItem, not just the buttons. I got the following links on googling.

• Stack Overflow Question 1
• Stack Overflow Question 2

The first question doesn't have an answer and the answer to the second question doesn't solve my problem, because it is the UINavigationItem itself which I want to hide, not just the buttons. I tried setting the topBar to none in interface builder and tried using the following code:

self.navigationController.toolbarHidden = YES;

In the viewDidLoad but nothing helped a bit. When I comment off the following line from the AppDelegate's didFinishLaunchingWithOptions: method, the view is fine, but then the ad won't show up.

self.window.rootViewController = self.bannerViewController;

What can be done to rectify this?

Answer 1

To hide navigationbar use navigationBarHidden property. Like,

self.navigationController.navigationBarHidden = YES;

for you reference check, UINavigationController Class Reference

if you want to animate your navigationBar while hiding, use

[self.navigationController setNavigationBarHidden:YES animated:YES]
