Solved: hide navigation bar

While the trend of full-screen applications has its advantages, developers must be aware that a hidden navigation bar could pose navigational issues for users. An appealing, user-friendly application interface often relies heavily on well-implemented navigation structures. This article will guide you to efficiently hide the navigation bar in Swift with complete in-depth analysis and examples.

To hide the navigation bar in your ‘Swift’ application, you can simply apply the ‘isNavigationBarHidden’ property of your navigationController and set it to ‘true’ in your viewDidLoad method.

override func viewDidLoad() {
self.navigationController?.isNavigationBarHidden = true

Understanding the Navigation Controller

The navigation controller manages the navigation bar at the top of the interface and an optional toolbar at the bottom. You might wonder why we would want to hide such a crucial component. There are various scenarios in which it might be beneficial. For instance, to provide a more immersive user experience in certain sections of your application or to utilize the extra screen space.

Navigation Controllers in Swift manage the navigation hierarchy of your application. They stack view controllers, providing a visual representation of where users are in the app and how they got there. A hidden navigation bar can significantly decrease user confusion for a smoother navigational experience.

Dive Deeper into ‘isNavigationBarHidden’

Getting to the roots, ‘isNavigationBarHidden’ is a Boolean property that can either be set to ‘true’ or ‘false’. When set to ‘true’, it hides the navigation bar, and vice versa.

Here’s a simple implementation of ‘isNavigationBarHidden’:

override func viewWillAppear(_ animated: Bool) {
    self.navigationController?.setNavigationBarHidden(true, animated: true)

This method is called just before the view controller becomes visible to the user. By calling ‘setNavigationBarHidden’, the appearance of the navigation is changed and hence the navigation bar is hidden just before the view appears. This provides a seamless experience to the user as this approach prevents the brief appearance of the navigation bar before being hidden.

Working with libraries such as UIKit, employing Swift’s extensive features, and understanding the usage of properties such as ‘isNavigationBarHidden’, it’s possible to construct a more flexible, user-focused navigation system for applications. The enhancement of user experience by these marginal tweaks can have a significant impact on your application’s usability, making the learning curve for your application less steep for new users.
