如何更改導航欄默認的后退按鈕

Question

嗨，我無法更改導航欄默認后退按鈕的標題

我已經嘗試過了：

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

Answer 1

設置為leftBarButtonItem

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

self.navigationItem.leftBarButtonItem = backBtn
