问题描述

这是我根据

Here is what I have based on this answer. The code currently allows the user to select a cell but I cannot distinguish which cell is selected or execute any code in response to the selection. In summary, how can I execute code based on the selected cell's name and execute on click. The cell currently highlights in blue where clicked, but I want to identify it and act accordingly based on that selection. Note: I am not looking to select the cell in editing mode. Also, how can I programmatically select a cell without click?

struct OtherView: View {
    @State var list: [String]
    @State var selectKeeper = Set<String>()

    var body: some View {
        NavigationView {
            List(list, id: \.self, selection: $selectKeeper) { item in
                Text(item)
            }
        }
    }
}

推荐答案

我找到了一种解决方法,但必须单击文本本身-单击单元格无济于事:

I found a workaround, but the text itself has to be clicked- clicking the cell does nothing:

struct OtherView: View {
    @State var list: [String]
    @State var selectKeeper = Set<String>()

    var body: some View {
        NavigationView {
            List(list, id: \.self, selection: $selectKeeper) { item in
                Text(item)
                  .onTapGesture {
                     print(item)
                  }
            }
        }
    }
}
