Answer 1

尝试一下：

override func viewDidLoad() {
    super.viewDidLoad()

    var button = UIBarButtonItem(title: "YourNewButton", style: UIBarButtonItemStyle.Bordered, target: self, action: "doSomething")
    self.navigationItem.leftBarButtonItem = button

}

func doSomething()
{
    //do something
    var vc = YourDestinationViewController()

    self.presentViewController(vc, animated: true, completion: nil)
}
