Hide Navigation Bar in Specific View - Swift 3
ios, swift3, uinavigationbar, uinavigationcontroller, xcode8.2
Solution
Move that code to `viewWillAppear()` instead of `viewDidLoad()`.
`viewDidLoad()` is only called once per instantiated view controller, whereas `viewWillAppear()` is called whenever the view controller is about to be presented on screen.

Problem
I have NavigationController that handles navigation through my app. According to my design, the very first view should have no visible NavigationBar. All the others after, will. In this FirstView, I'm using this so far to hide the NavBar, inside the ViewDidLoad: ``` self.navigationController?.isNavigationBarHidden = true ``` From this FirstView I can access other Views. In these other views I show the NavBar using: ``` self.navigationController?.isNavigationBarHidden = false ``` My problem is that: - When I navigate from a View with Visible NavBar, back to the FirstView with the Hidden NavBar, the NavBar is now visible. Basically the NavBar only hides the very first time then shows if I use the back button. How Can I Prevent this ? Thank you!
