如何更改导航栏默认后退按钮

Question

您好，我无法更改导航栏默认后退按钮的标题

我试过了：

  self.navigationController?.navigationBar.backItem?.title="retour"
        self.navigationController?.navigationItem.leftBarButtonItem?.title="retour"
        self.navigationItem.backBarButtonItem?.title="retour"
        self.navigationItem.leftBarButtonItem?.title="retour"

Answer 1

设为leftBarButtonItem

var backBtn : UIBarButtonItem = UIBarButtonItem(title: "retour", style: UIBarButtonItemStyle.Plain, target: self, action: nil)

self.navigationItem.leftBarButtonItem = backBtn
