我需要一些帮助来尝试在Swift UI中使用.searchable。
我试图展示一些与搜索字符串相关联的数据。
例如，用户搜索某个描述，代码/价格也显示在行中。我不想在新视图中显示数据，只是在用户键入时动态显示。
具有值的行
我所面临的问题是，我找不到一种方法来操纵计算出的值"；搜索结果"；以及通用的"；named:在ForEach循环中。
我理解"；搜索结果"；是一个数组，但我无法访问它。
之所以添加removalAll，是因为每次我回到这个视图时，每次在搜索栏中键入字符时，它都会复制列表。
我把数据作为一个枚举，并存储在一个数组中，因为当时它在我需要迭代数据的情况下是有意义的。
有什么建议吗？
提前谢谢！
以下是主要视图：
struct ContentView: View {
@State private var searchText = ""
var body: some View {
storedOtherWoundsNames.removeAll()
self.createOtherWound()
return
NavigationView {
List {
ForEach(searchResults, id: .self) { named in
VStack {
VStack {
Text(named) //search result
.frame(maxWidth: .infinity, alignment: .leading)
.font(.caption)
}
HStack {
Text("(named) Code") //want to display from the array "storedOtherWoundsCodes"
.frame(maxWidth: .infinity, alignment: .leading)
.font(.caption)
Text("(named) Value") //want to display from the array "storedOtherWoundsValues"
.frame(maxWidth: .infinity, alignment: .trailing)
}
}
.padding(.all)
.border(Color.gray)
}
}
}
.searchable(text: $searchText)
}
var searchResults: [String] {
if searchText.isEmpty {
storedOtherWoundsNames.removeAll()
return storedOtherWoundsNames
} else {
return storedOtherWoundsNames.filter{$0.contains(searchText)
}
}
}
func createOtherWound() { //takes enum and places it in array
for otherWoundName in allOtherWoundsNames {
storedOtherWoundsNames.append(otherWoundName.rawValue)
}
for otherWoundCode in allOtherWoundsCodes {
storedOtherWoundsCodes.append(otherWoundCode.rawValue)
}
for otherWoundValue in allOtherWoundsValues {
storedOtherWoundsValues.append(otherWoundValue.rawValue)
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
如果有帮助的话，以下是数据：

let allOtherWoundsNames = OtherWoundsName.allCases

尝试示例代码中所示的方法，其中数据位于结构数组([DataModel](中，并且搜索返回一个过滤后的数组；访问"；name、code和value每个项目的。
struct ContentView: View {
@State private var searchText = ""
@State var items = [DataModel]()
var searchResults: [DataModel] {
searchText.isEmpty ? [] : items.filter{$0.name.contains(searchText)}
// or alternatively
// searchText.isEmpty ? items : items.filter{$0.name.contains(searchText)}
}
var body: some View {
NavigationView {
List {
ForEach(searchResults) { item in
VStack {
Text(item.name).font(.caption)
HStack {
Text(item.code).font(.caption).foregroundColor(.red)
Text("(item.value)").foregroundColor(.blue)
}
}
.frame(maxWidth: .infinity, alignment: .leading)
.padding(.all)
.border(Color.gray)
}
}
}
.searchable(text: $searchText)
.onAppear {
items = [DataModel(name: "Secondary Closure", code: "Z738", value: 97.35),
DataModel(name: "Muscle Repair (including skin)", code: "R525", value: 88.60),
DataModel(name: "Debride Wound/Ulcer - One", code: "Z080", value: 20)]
// etc...
}
}
}
struct DataModel: Identifiable {
let id = UUID()
var name: String
var code: String
var value: Double
}
