小编ale*_*rov的帖子

我试图在我的应用程序中隐藏搜索栏，就像 Apple 在他们的消息应用程序中所做的那样：

我已经在 SwiftUI 中实现了 UISearchBar：

struct SearchBar: UIViewRepresentable {
@Binding var text: String

class Coordinator: NSObject, UISearchBarDelegate {
    @Binding var text: String

    init(text: Binding<String>) {
        _text = text
    }

    func searchBar(_: UISearchBar, textDidChange searchText: String) {
        text = searchText
    }
}

func makeCoordinator() -> SearchBar.Coordinator {
    return Coordinator(text: $text)
}

func makeUIView(context: UIViewRepresentableContext<SearchBar>) -> UISearchBar {
    let searchBar = UISearchBar(frame: .zero)
    searchBar.delegate = context.coordinator
    searchBar.searchBarStyle = .minimal
    searchBar.placeholder = "????? ?? ????????, ???????? ??? ????????"
    return searchBar
} …

我将我的项目嵌入到导航链接的列表（行）中

我的物品变成蓝色点击

这是我的代码：

玩具行.swift

struct ToyRow: View {\n    var category: String\n    var toys:[Toy]\n\n    var body: some View {\n\n        Group {\n            VStack{\n\n                VStack(alignment: .leading){\n                    Text(category).padding().font(.largeTitle)\n                    ScrollView(.horizontal, showsIndicators: false){\n                        HStack(alignment: .top){\n                            ForEach(self.toys){\n                                toy1 in\n                                NavigationLink(destination: ToyDetail(toy: toy1)) {\n                                    ToyItem(toy: toy1)\n                                }.padding()\n\n                            }\n                        }\n                    }\n\n                }\n            }\n        }\n\n    }\n}\n

所以创建 NavigationView 没有帮助 \xe2\x80\x93\xe2\x80\x93 它变成灰色
