SwiftUI-细节弹出后，表单中的NavigationLink单元格保持突出显示 [英] SwiftUI - NavigationLink cell in a Form stays highlighted after detail pop

问题描述

在iOS 14中，在 Form 上下文中返回后，似乎未取消选择 NavigationLink s.对于 Form Picker s以及导致列表中另一个 View 呈现的其他任何条件(将突出显示上下文呈现给呈现)也是如此单元格).

In iOS 14, it appears that NavigationLinks do not become deselected after returning in a Form context. This is also true for Form Pickers and anything else that causes the presentation of another View from a list (giving a highlight context to the presenting cell).

我在iOS 13中没有注意到这种行为.

I didn't notice this behaviour in iOS 13.

一旦其他视图关闭，是否有办法取消选择"突出显示的行?

Is there a way to 'deselect' the highlighted row once the other view is dismissed?

示例代码:

struct ContentView: View {

    var body: some View {
        Form {
            NavigationLink(destination: Text("Detail")) {
                Text("Link")
            } 
        }
    }

}

推荐答案

在我的情况下，当在我的 NavigationView 之间使用任何Viewcontent(例如Text()，Image()，...)时，就会出现此行为>和 List/Form .

In my case this behaviour appeared when using any Viewcontent (e.g. Text(), Image(), ...) between my NavigationView and List/Form.

var body: some View {
    
    NavigationView {
        VStack {
            Text("This text DOES make problems.")
            List {
                NavigationLink(destination: Text("Doesn't work correct")) {
                    Text("Doesn't work correct")
                }
            }
        }
    }
}

将Text()放在下面下不会出现任何问题:

Putting the Text() beneath the List does not make any problems:

var body: some View {
    
    NavigationView {
        VStack {
            List {
                NavigationLink(destination: Text("Does work correct")) {
                    Text("Does work correct")
                }
            }
            Text("This text doesn't make problems.")
        }
    }
}

这绝对是XCode 12错误.随着越来越多的人报告此问题，早日得到解决.

This is definitely a XCode 12 bug. As more people report this, as earlier it gets resolved.
