Restore original back button behavior
In a UIViewController viewDidLoad method I customize icon and behavior of the navigation left button this way:
let backButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.action, target:self, action:#selector(handleBack))
self.navigationItem.leftBarButtonItem = backButton
Is there any way to restore its original appearence and behavior?
Solution
self.navigationItem.leftBarButtonItem = nil
self.navigationItem.hidesBackButton = NO
