Hide back button in navigation bar with hidesBackButton in Swift
提问by Amer Hukic
I want to hide the back button when transitioning from one view to another. I read the questions regarding this problem and every answer was "use hidesBackButton". The problem with this is:
从一个视图转换到另一个视图时，我想隐藏后退按钮。我阅读了有关此问题的问题，每个答案都是“使用hidesBackButton”。问题在于：
when I put it in viewDidLoad/viewWillAppear the back button arrow hides but the string "Back" doesn't.
when I put it in viewDidAppear the back button disappears but it visible to the user
当我把它放在 viewDidLoad/viewWillAppear 中时，后退按钮箭头会隐藏，但字符串“后退”没有。
当我把它放在 viewDidAppear 中时，后退按钮消失了，但它对用户可见
How can I fix this?
我怎样才能解决这个问题？

Here is how you can replicate this problem(or bug?)
Make a new Tabbed application with Swift in Xcode. In the FirstViewController.swift use performSegueWithIdentifier to navigate to the second view controller. In the SecondViewController.swift hide the navigation bar back button using hidesBackButton and you will see what the problem is.
以下是如何复制此问题（或错误？）
在 Xcode 中使用 Swift 创建一个新的选项卡式应用程序。在 FirstViewController.swift 中使用 performSegueWithIdentifier 导航到第二个视图控制器。在 SecondViewController.swift 中使用 hidesBackButton 隐藏导航栏后退按钮，您将看到问题所在。

Worked for me when I set it in init(), instead of viewDidLoad. Strange though
当我在 init() 中设置它而不是 viewDidLoad 时对我有用。虽然奇怪

In XCode 11(maybe sooner, not sure), you can also untick the box under the attribute inspector tab in the storyboard editor if you're not looking to do it programatically.
在 XCode 11（也许更快，不确定）中，如果您不想以编程方式进行，也可以取消选中故事板编辑器中属性检查器选项卡下的框。
