swift - 如何在 `User_Mention`中按 `SearchBar`进行过滤

Question

我使用搜索栏来允许用户根据他输入的内容过滤列表。

但是如何允许“@”User_Mention也搜索此列表呢？

这是我的尝试，但不起作用:

      var searchText = ""
var body : some View{
    List(observedData.datas.filter{
        $0.msg.lowercased().contains(searchText.lowercased()) || searchText.lowercased() == "" ||
        $0.name.lowercased().contains("@"+searchText.lowercased()) || "@"+searchText.lowercased() == ""

    }

         ))

    {
        i in
        VStack(alignment: .leading){
            CellCard(userId:i.userId,user: i.name)
        }
    }

    .listStyle(GroupedListStyle())
    .environment(\.horizontalSizeClass, .regular)
}

Answer 1

这样解决:

$0.msg.lowercased().contains(searchText.lowercased()) || "@\($0.name)".lowercased().contains(searchText.lowercased()) || searchText.lowercased() == ""
