Left Bar Button Item - show name of previous View Controller

Question

Solution

Add this in viewController where you want to have default back button and custom bar button item. You can customise the bar button item.

override func viewDidLoad() {
    super.viewDidLoad()
    let newBtn = UIBarButtonItem(title: "new", style: .plain, target: self, action: #selector(anotherMethod))
    self.navigationItem.leftItemsSupplementBackButton = true
    self.navigationItem.leftBarButtonItem = newBtn//self.navigationItem.leftBarButtonItems = [newBtn,anotherBtn]
}
