如何在导航栏中添加右键？ [英] How to add right button in the navigation bar?

问题描述

我有一个问题要在导航栏中添加一个右键..

I have a question to add a right button in navigation bar..

我有两个观点：查看A和查看B

I have two views: View A and View B

在我使用 self.navigationController！.pushViewController 显示视图B后，我添加了一个导航栏来查看A.

I add a navigation bar to view A, after I used self.navigationController!.pushViewController to show view B.

在自动导航栏左侧显示一个后退按钮，很不错。但现在我想在视图B的导航栏右侧添加一个按钮..
我已经尝试了一些答案，但它不起作用...

推荐答案

当您使用这种语言时，Vahan Babayan的答案的Swift版本是：

The Swift version of Vahan Babayan's answer, as you seem to use this language, is:

let rightButtonItem = UIBarButtonItem.init(
      title: "Title", 
      style: .Done, 
      target: self, 
      action: "rightButtonAction:"
)

self.navigationItem.rightBarButtonItem = rightButtonItem

将在self上调用以下方法：

The following method will be called on self:

func rightButtonAction(sender: UIBarButtonItem)

请注意，所有这些都可以使用Storyboard 以图形方式设置，方法是将条形按钮项拖动到导航项并右键单击以设置目标操作。

Note that all this can be set graphically using a Storyboard, by dragging a Bar Button Item to your Navigation Item and right-clicking to set a target-action.

自Swift 3和4以来的一个小更新：编译器现在可以检查选择器名称，以编程方式设置目标操作时防止打字错误。所以应该真正使用：

A small update since Swift 3 and 4 are out: the compiler can now check selector names, preventing typos when setting up target-action programatically. So one should really use:

let rightButtonItem = UIBarButtonItem.init(
      title: "Title", 
      style: .Done, 
      target: self, 
      action: #selector(rightButtonAction(sender:))
)
