Question

我一直在尝试将自定义后退按钮添加到正在使用Multi-Storyboard设置的Load栏上创建的导航栏，因此后退按钮不会自动出现，而且我正在尝试使用它的自定义图像。

这是我到目前为止所做的：

class AddFundsMethodTable : UITableViewController {

override func viewDidLoad() {
    super.viewDidLoad()
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

override func viewWillAppear(animated: Bool) {
    self.styleNavBar()
}

func styleNavBar() {
    var newNavBar = UINavigationBar(frame: CGRectMake(0,0, CGRectGetWidth(self.view.frame), 100.0))
    newNavBar.tintColor = UIColor.whiteColor()

    var navItem = UINavigationItem(title: "Choose a Method")
    var backImage = UIImage(named: "backBtn")
    var backItem = UIBarButtonItem(image: backImage, style: .Plain, target: self, action: "backButton:")
    navItem.leftBarButtonItem = backItem
    newNavBar.setItems([navItem], animated: false)

    self.view.addSubview(newNavBar)
}

func backButton(sender: UIBarButtonItem) {
    self.navigationController?.popToRootViewControllerAnimated(true)
}

}

在ViewDidLoad中写下这个：

override func viewDidLoad() {
  super.viewDidLoad()
  self.styleNavBar()
}
