这对我很管用。斯威夫特5

navigationItem.backButtonTitle = ""

Swift 4 -在按任何视图控制器之前配置后退按钮

// if you want to remove the text
navigationItem.backBarButtonItem = UIBarButtonItem()

// if you want to modify the text to "back"
navigationItem.backBarButtonItem = UIBarButtonItem(title: "back", style: .plain, target: nil, action: nil)

你可以从接口生成器这样做:

单击上一个视图控制器的导航项

在属性检查器中，将后退按钮文本设置为您想要的任何文本。这就是它! !

back按钮属于前一个视图控制器，而不是当前显示在屏幕上的那个。 要修改返回按钮，你应该在按之前更新它，在启动segue的视图控制器上:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    let backItem = UIBarButtonItem()
    backItem.title = "Something Else"
    navigationItem.backBarButtonItem = backItem // This will show in the next view controller being pushed
}

Swift 3,4和5:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    let backItem = UIBarButtonItem()
    backItem.title = "Something Else"
    navigationItem.backBarButtonItem = backItem // This will show in the next view controller being pushed
}

OR

// in your viewDidLoad or viewWillAppear
navigationItem.backBarButtonItem = UIBarButtonItem(
    title: "Something Else", style: .plain, target: nil, action: nil)

有两种不同的方法来植入那部分，  

1.

navigationItem.backButtonTitle = "Title Goes Here"

(5)迅速

  2.

 let backButton = UIBarButtonItem()

backButton。title = "标题在这里" self.navigationController .navigationBar.topItem ?。backBarButtonItem = backButton

override func viewWillAppear(_ animated: Bool) {

    self.tabBarController?.navigationItem.title = "Notes"

    let sendButton = UIBarButtonItem(title: "New", style: .plain, target: self, action: #selector(goToNoteEditorViewController))

    self.tabBarController?.navigationItem.rightBarButtonItem = sendButton
}

func goToNoteEditorViewController(){
   // action what you want
}

希望能有所帮助!!3 #迅速
