Present the opening view modally, or;

<ol>
<li>don't add it to your navigation controller</li>
<li>present it before the navigation controller.</li>
<li>Once everything has loaded, dismiss the opening view and show the navigation controller (both without animation).</li>

Try this method inside a view controller:

<pre><code>// swift
self.navigationController?.setNavigationBarHidden(true, animated: true)

// objective-c
[self.navigationController setNavigationBarHidden:YES animated:YES]; 
</code></pre>

More clarifications:

<code>UINavigationController</code> has a property navigationBarHidden, that allows you to hide/show the navigation bar for the whole nav controller.

Let's look at the next hierarchy:

<pre><code>--UINavigationController
------UIViewController1
------UIViewController2
------UIViewController3
</code></pre>

Each of three UIViewController has the same nav bar since they are in the UINavigationController. For example, you want to hide the bar for the UIViewController2 (actually it doesn't matter in which one), then write in your UIViewController2:

<pre><code>- (void)viewWillAppear:(BOOL)animated {
 [super viewWillAppear:animated];
 [self.navigationController setNavigationBarHidden:YES animated:YES]; //it hides the bar
}

- (void)viewWillDisappear:(BOOL)animated {
 [super viewWillDisappear:animated];
 [self.navigationController setNavigationBarHidden:NO animated:YES]; // it shows the bar back
}
</code></pre>

Use below one line code to hide Navigation bar in Swift3 and Swift4

<pre><code>navigationController?.setNavigationBarHidden(true, animated: true)
</code></pre>

To show Navigation bar

<pre><code>navigationController?.setNavigationBarHidden(false, animated: true)
</code></pre>

This is worked for me:

 super.viewWillAppear(animated)
 navigationController?.setNavigationBarHidden(true, animated: false)
}

//reappears navigation bar on next page
override func viewWillDisappear(_ animated: Bool) {

It is better to remember if it was hidden previously:

<pre><code>private var navigationBarWasHidden = false

override func viewWillAppear(_ animated: Bool) {
 super.viewWillAppear(animated)

 // Save if it was hidden initially
 self.navigationBarWasHidden = self.navigationController?.isNavigationBarHidden ?? false
 // Hide the Navigation Bar
 self.navigationController?.setNavigationBarHidden(true, animated: animated)
}

override func viewWillDisappear(_ animated: Bool) {
 super.viewWillDisappear(animated)

 // Show the Navigation Bar
 self.navigationController?.setNavigationBarHidden(self.navigationBarWasHidden, animated: animated)
}

I've created a two splash screen iPhone app. Afterwards user is taken to first view. I've added a UINavigationController. It works perfectly fine. 

How do I remove the navigation bar for the opening view alone?

MainWindow

<pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 


self.splashScreen = [[SplashScreen alloc] 
 initWithNibName:@"SplashScreen" 
 bundle:nil];
if (self.pageController == nil) {
openingpage *page=[[openingpage alloc]initWithNibName:@"openingpage" bundle:[NSBundle mainBundle]];
 self.pageController = page;
 [page release];
}
[self.navigationController pushViewController:self.pageController animated:YES];

[window addSubview:splashScreen.view];

 [splashScreen displayScreen];
[self.window makeKeyAndVisible];

return YES;
 }
</code></pre>
