Hide back button in navigation bar with hidesBackB

问题:

I want to hide the back button when transitioning from one view to another. I read the questions regarding this problem and every answer was "use hidesBackButton". The problem with this is:

• when I put it in viewDidLoad/viewWillAppear the back button arrow hides but the string "Back" doesn't.

• when I put it in viewDidAppear the back button disappears but it visible to the user

How can I fix this?

Edit:

Here is how you can replicate this problem(or bug?)
Make a new Tabbed application with Swift in Xcode. In the FirstViewController.swift use performSegueWithIdentifier to navigate to the second view controller. In the SecondViewController.swift hide the navigation bar back button using hidesBackButton and you will see what the problem is.

Try adding this:

let backButton = UIBarButtonItem(title: "", style: .Plain, target: navigationController, action: nil)
navigationItem.leftBarButtonItem = backButton

To hide the back button with the latest Swift:

self.navigationItem.setHidesBackButton(true, animated: false)

this worked for me

navigationController?.navigationBar.topItem?.hidesBackButton = true

回答5:

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.

    self.navigationController?.navigationBarHidden = false
    var button: UIButton = UIButton()
    button.setImage(UIImage(named: "person-icon.jpg"), forState: .Normal)
    button.frame = CGRectMake(0, 0, 25, 25)
    button.targetForAction("actioncall", withSender: nil)
    var rightItem:UIBarButtonItem = UIBarButtonItem()
    rightItem.customView = button
    self.navigationItem.rightBarButtonItem = rightItem

    let backButton = UIBarButtonItem(title: "", style: UIBarButtonItemStyle.Plain, target: navigationController, action: nil)
    navigationItem.leftBarButtonItem = backButton
}

override func viewWillAppear(animated: Bool) {
    let backButton = UIBarButtonItem(title: "", style: UIBarButtonItemStyle.Plain, target: navigationController, action: nil)
    navigationItem.leftBarButtonItem = backButton
}

Worked for me when I set it in init(), instead of viewDidLoad. Strange though
