iPhone hide Navigation Bar only on first page

📱🚀 Ultimate Guide: How to Hide iPhone Navigation Bar on the First Page 🚀📱

Are you tired of seeing the boring old navigation bar on every page of your iPhone app? Want to make it disappear like magic? Well, you've come to the right place! In this guide, I'll show you how to hide the navigation bar only on the first page of your app, making it more immersive and giving your users a seamless experience. Let's dive in! 💦

⚠️ The Problem ⚠️

You've probably stumbled upon the code snippet mentioned above, which hides and shows the navigation bar in different situations. The initial problem is that once you hide the bar on the first page, you can't seem to find the right event or action to trigger it to hide again when users navigate back to the root view. Furthermore, the manual "test" button does the job but adds unnecessary clutter to your app's user interface.

🗝️ The Solution 🗝️

Fortunately, there's a simple and elegant solution to this problem. We'll leverage the power of the UIViewControllerAnimatedTransitioning protocol to automatically hide the navigation bar when users navigate back to the root view. Here's how you can do it:

Step 1: Create a Custom Animator Class Create a new class, let's call it CustomAnimator, and make it conform to the UIViewControllerAnimatedTransitioning protocol.

import UIKit

class CustomAnimator: NSObject, UIViewControllerAnimatedTransitioning {
    
    func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
        let fromViewController = transitionContext.viewController(forKey: .from)
        let toViewController = transitionContext.viewController(forKey: .to)
        
        if let fromViewController = fromViewController, fromViewController.isKind(of: YourRootViewController.self) {
            // Hide the navigation bar when transitioning back to the root view
            fromViewController.navigationController?.setNavigationBarHidden(true, animated: false)
        }
        
        // Implement your desired transition animation
        
        transitionContext.completeTransition(true)
    }
    
    func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
        return 0.3 // Set your desired duration
    }
    
}

Step 2: Set Up the Navigation Controller Inside your app delegate's application(_:didFinishLaunchingWithOptions:) method, set the navigation controller's delegate to an instance of the custom animator class we just created.

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    let navigationController = UINavigationController(rootViewController: YourRootViewController())
    navigationController.delegate = CustomAnimator()
    
    // Set up your app's window and root view controller
    
    return true
}

🎉 That's it! 🎉

Now, whenever users navigate back to the root view, the navigation bar will automatically hide without any additional buttons or manual actions. Isn't that cool? 😎

💥 Bonus Tip 💥

If you want to hide the navigation bar only on the first page and show it on all other pages, make the following modification in the CustomAnimator class:

if let fromViewController = fromViewController, fromViewController.isKind(of: YourRootViewController.self) {
    // Hide the navigation bar when transitioning back to the root view
    fromViewController.navigationController?.setNavigationBarHidden(true, animated: false)
} else {
    // Show the navigation bar for all other views
    fromViewController?.navigationController?.setNavigationBarHidden(false, animated: false)
}
