SwiftUI 在子视图中隐藏 TabBar

问题描述

我正在使用 SwiftUI，但 TabBar 有一些问题.我想隐藏特定子视图上的 TabBar.

I am working with SwiftUI, and I have some issues with the TabBar.I want to hide the TabBar on a specific subview.

尝试过

UITabBar.appearance().isHidden = true

它仅适用于 TabView 中的直接视图.但是当我把它放在子视图中时它不起作用.

It only works on the direct views in the TabView. But when I place it in a subview it doesn't work.

有没有人解决这个问题?

Have anyone a solution for this?

谢谢.

推荐答案

iOS 14

安装 Introspect SwiftPM:https://github.com/siteline/SwiftUI-Introspect

struct SomeView: View{

    @State var uiTabarController: UITabBarController?

    var body: some View {
        List {
            -your code here-
        }

        .navigationBarTitle("Title", displayMode: .inline)
        .introspectTabBarController { (UITabBarController) in
            UITabBarController.tabBar.isHidden = true
            uiTabarController = UITabBarController
        }.onDisappear{
            uiTabarController?.tabBar.isHidden = false
        }
    }
}

在uiTabarController中的这段代码中，我们引用了UITabarController.当我们返回时，我们再次启用了 Tabar.所以，这就是为什么需要这样做.

In this code in uiTabarController, we are taking the reference of UITabarController. When we go back then we enabled the Tabar again. So, that's why this is needed.
