SwiftUI在子视图中隐藏TabBar [英] SwiftUI hide TabBar in subview

问题描述

我正在使用SwiftUI，并且TabBar出现了一些问题.我想在特定的子视图上隐藏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，当我将其放置在子视图中时，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.

有人对此有解决方案吗?

Have anyone a solution for this?

谢谢.

iOS 14简单解决方案

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

var body: some View {
    List {
        -your code here-
    }
    
    .navigationBarTitle("Title", displayMode: .inline)
    .introspectTabBarController { (UITabBarController) in
        UITabBarController.tabBar.isHidden = true
    }
}

注意:您必须在父视图中重新启用它的TabBar，否则它仍将被隐藏.

NOTE: You have to re-enable the TabBar it in the parent view or it will still be hidden.

.introspectTabBarController { (UITabBarController) in
            UITabBarController.tabBar.isHidden = false
}
