How to disable back button in navigation bar

Question

Is there any official way how to set UIBarButtonItem.enabled property? I tried to set a backButtonItem in previous controller. But enabled property

Answer 1

Don't try to disable your custom back button (won't work), just set a new one which is disabled. You can reach the previous navigation item through the UINavigationBar.backItem property.

// set disabled back button
let backButton = UIBarButtonItem(title: "Back", style: UIBarButtonItem.Style.plain, target: nil, action: nil)
backButton.isEnabled = false
navigationController?.navigationBar.backItem?.backBarButtonItem = backButton

// disable pop gesture
navigationController?.interactivePopGestureRecognizer?.isEnabled = false
