Ios 如何在导航栏右侧添加多个 UIBarButtonItem

发布于05月20日

我希望UINavigationBar号的右边有UIBarButtonItem张以上的单张.我怎样才能做到这一点呢？

我正在try 的一个示例如下所示-您可以注意到右上角有多个按钮.

在此处输入图像描述

推荐答案

在swift中使用:

override func viewDidLoad() {
  super.viewDidLoad()

  let editImage    = UIImage(named: "plus")!
  let searchImage  = UIImage(named: "search")!

  let editButton   = UIBarButtonItem(image: editImage,  style: .Plain, target: self, action: "didTapEditButton:")
  let searchButton = UIBarButtonItem(image: searchImage,  style: .Plain, target: self, action: "didTapSearchButton:")

  navigationItem.rightBarButtonItems = [editButton, searchButton]
}

按如下方式编写操作函数:

func didTapEditButton(sender: AnyObject){
    ...
}

func didTapSearchButton(sender: AnyObject){
    ...
}

Swift 4 & 5个

    override func viewDidLoad() {
        super.viewDidLoad()
        let editImage    = UIImage(named: "edit")!
        let searchImage  = UIImage(named: "search")!

        let editButton   = UIBarButtonItem(image: editImage,  style: .plain, target: self, action: #selector(didTapEditButton(sender:)))
        let searchButton = UIBarButtonItem(image: searchImage,  style: .plain, target: self, action: #selector(didTapSearchButton(sender:)))

        navigationItem.rightBarButtonItems = [editButton, searchButton]
    }

    @objc func didTapEditButton(sender: AnyObject){

    }

    @objc func didTapSearchButton(sender: AnyObject){

    }
