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

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)

这应该可以工作:
override func viewDidLoad() {
super.viewDidLoad()
var button = UIBarButtonItem(title: "YourTitle", style: UIBarButtonItemStyle.Bordered, target: self, action: "goBack")
self.navigationItem.backBarButtonItem = button
}
func goBack()
{
self.navigationController?.popViewControllerAnimated(true)
}
虽然不建议这样做，因为这实际上取代了backButton，它也删除了后退箭头和滑动手势。
后退按钮文本和彩色文本:
navigationController?.navigationBar.tintColor = .red
navigationController?.navigationBar.topItem?.backButtonTitle = "Hi"

如果你对任何多星建议有问题，确保你在viewDidLoad()中注册你的UITableViewCells，而不是从init()
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
}
