ios - 在 LeftBarButtonItems ios 中使用自定义按钮创建默认后退按钮

Question

我正在创建一个项目，我需要在导航栏左侧有一个默认后退按钮和自定义过滤器按钮。

我创建了自定义后退按钮、自定义过滤器按钮并将它们添加到 leftBarButtonItems

navigationItem.leftBarButtonItems = alignedLeftBarButtonItems()

    func alignedLeftBarButtonItems() -> [UIBarButtonItem] {

            let filterButton = createLeftCustomBarButton()

            // back button creation
            let backButton = UIBarButtonItem(image: R.image.navBackArrow(), style: .plain, target: self, action: #selector(self.backButtonPressed(_:)))
            backButton.tintColor = UIColor.white

            let barButtonsItems = [
                backButton,
                UIBarButtonItem(customView: filterButton)
            ]
            return barButtonsItems
        }

一切都很好并且工作正常。

关注:

Default, User can go to the previous VC by sliding from left to right. This functionality is lost in making this. Is there a way I can have both buttons with the sliding functionality.

Answer 1

您需要使用 UIBarButtonItem 来使用后退按钮的默认向左或向右滑动功能:

let backButton = UIBarButtonItem(image: Image.backButton, style: UIBarButtonItemStyle.plain, target: self, action: #selector(actionBackButton))
self.navigationItem.leftBarButtonItem = backButton

With Custom button, you cannot get this functionality
