如何删除后退按钮的文本。

当前返回按钮:

<返回

需要的后退按钮:

< 其他任何东西

这些都没有奏效:

self.navigationItem.backBarButtonItem?.title = "Back"
self.backItem?.title = ""
self.navigationController?.navigationBar.backItem?.title = ""
self.navigationItem.backBarButtonItem?.title = ""
self.navigationController?.navigationItem.backBarButtonItem?.title="Back"
self.navigationController?.navigationBar.backItem?.title = ""
self.navigationController?.navigationItem.backBarButtonItem?.title

我不知道你在哪里使用了你的方法,你把你的问题,但我可以得到想要的结果,如果我使用,在我的ViewController类(其中我想改变后退按钮),在viewDidLoad()函数,以下一行:

self.navigationController?.navigationBar.backItem?.title = "Anything Else"

结果将是:

之前

在我的案例中,解决方案是在移动到子视图控制器之前清除主视图控制器的导航项。如果再次显示,请重新设置

MasterController

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    navigationItem.title = "Master Title"
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    navigationItem.title = ""
}

这就是我如何推送一个UIViewController并清除子控制器中的后栏按钮项:

MasterController

let childController = ChildController(collectionViewLayout: UICollectionViewFlowLayout())
childController.navigationItem.backBarButtonItem?.title = ""
navigationController?.pushViewController(childController, animated: true)

你可以把这3行代码放到ViewController中你想要改变返回按钮的标题。

在你的重载函数中viewDidLoad(){}。

let backButton = UIBarButtonItem()
backButton.title = "My Back Button Title"
self.navigationController?.navigationBar.topItem?.backBarButtonItem = backButton

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)

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

 

自我。标题= "" 之前self.navigationController ?。pushViewController(vc, animated: true)。
