Disable Rotation of UIViewController Embedded Into UINavigationController

In this short Swift code example we will learn how to disable rotation of the UIViewController which is embedded into UINavigationController.

  • We will need to override shouldAutorotate function and return a value of false
  • Add to current UIViewController a UINavigationController extension

Disable Rotation of UIViewController Complete Code Example in Swift

  

import UIKit

class ViewController: UIViewController  {
    
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        
    }
    
    override open var shouldAutorotate: Bool {
        return false
    }
    
}

extension UINavigationController {
    
    override open var shouldAutorotate: Bool {
        get {
            if let visibleVC = visibleViewController {
                return visibleVC.shouldAutorotate
            }
            return super.shouldAutorotate
        }
    }
    
    override open var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
        get {
            if let visibleVC = visibleViewController {
                return visibleVC.preferredInterfaceOrientationForPresentation
            }
            return super.preferredInterfaceOrientationForPresentation
        }
    }
    
    override open var supportedInterfaceOrientations: UIInterfaceOrientationMask{
        get {
            if let visibleVC = visibleViewController {
                return visibleVC.supportedInterfaceOrientations
            }
            return super.supportedInterfaceOrientations
        }
    }}

  • Thanks for writing this, but how does it work when you’re pushng a new controller? Presumably it’s not visible yet, so the previous controller will be consulted to see which orientation to use. Does that happen? Or does it work reliably?
