条形按钮不显示-Swift

Question

I ran my app and I'm having a hard time removing the back button (My UITableViewController has a Navigation Controller with a relationship to a TabBar Controller) and adding the bar button to my app. Here's what it looks like in the storyboard:

Code:

    class FeedTableViewController: UITableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()


    }


    // MARK: - Table view data source

    override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        // #warning Potentially incomplete method implementation.
        // Return the number of sections.
        return 1
    }

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        // #warning Incomplete method implementation.
        // Return the number of rows in the section.
        return 0
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    override func viewWillAppear(animated: Bool) {
        self.navigationItem.hidesBackButton = true
    }


    @IBAction func publishPhoto(sender: AnyObject) {
        self.performSegueWithIdentifier("publishPhotoOrVideo", sender: self)
    }
}

You can programmatically create the rightBar Button using following code. you need to add following code in viewDidLoad method.

 var refreshButton = UIBarButtonItem(barButtonSystemItem: .Refresh, target: self, action: "buttonMethod") //Use a selector
    self.navigationItem.rightBarButtonItem = refreshButton

Or if you have reference then you can directly assign as followed.

self.navigationItem.rightBarButtonItem = publicPhotoButton

Hope this help you.
