编辑:您只能在List中使用onDelete,onMove和onInsert.如果要让用户删除ScrollView中的行,则必须自己实现某些功能.看看下面的代码,看一个简单(非常难看)的例子:struct ContentView: View { @State var valueData: [String] = ["Apple", "Pear", "Orange", "Cake"] var body: some View { NavigationView { ScrollView(.vertical) { VStack(spacing: 10) { DietListView(valueData: self.$valueData) DietListView(valueData: self.$valueData) .padding() } } .frame(width: 352) } }}struct DietListView: View { @Binding var valueData: [String] var body: some View { VStack { ScrollView { ForEach(self.valueData.indices, id: \.self) { idx in NavigationLink(destination: Text("ciao")) { HStack { Text(self.valueData[idx]) Spacer() Text("100") .padding(.trailing, 20) Button(action: { self.valueData.remove(at: idx) }) { Image(systemName: "xmark.circle") .resizable() .frame(width: 25, height: 25) .foregroundColor(Color.red) } } .foregroundColor(.primary) .padding([.leading, .trailing], 20) .padding([.top, .bottom], 10) } } } .frame(height: 300) } .frame(width: 352, height: 350) .background(Color.white) .cornerRadius(16) .shadow(radius: 10) }}#if DEBUGstruct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() }}#endifI code a List in a ScrollView, when I selected a List cell to translate to another view and return back, the cell selected indicator did not disappear after selecting.I hope after selected the list cell, the selected indicator should be disappear.I debugged, I found that the ScrollView has some problems when it worked with List.If no ScrollView, the list selection behavior is all right, if plus the ScrollView outside the list, the problem become.The other problem is How to remove the List Separator.Thank you for your help!!!@State var valueData: [String] = ["Apple", "Pear", "Orange", "Cake"]var body: some View { NavigationView { ScrollView(.vertical) { VStack(spacing: 10) { DietListView(valueData: self.$valueData) DietListView(valueData: self.$valueData) .padding() } } .frame(width: 352) }}struct DietListView: View { @Binding var valueData: [String] var body: some View { VStack { List { ForEach(self.valueData, id: \.self) { item in NavigationLink(destination: DietItemDetailView()) { HStack { Text(item) Spacer() Text("100") } } } .onDelete { index in self.valueData.remove(at: index.first!) } } .frame(height: 300) } .frame(width: 352, height: 350) .background(Color.white) .cornerRadius(16) .shadow(radius: 10) }}the problem just like this: 解决方案 At the moment (SwiftUI Beta 5) you can't customise List very much changing, for example, the divider style. What you can do, depending on your needs, is to use a ScrollView with ForEach and give the cell the style you want. For example:struct ContentView: View { @State var valueData: [String] = ["Apple", "Pear", "Orange", "Cake"] var body: some View { NavigationView { ScrollView(.vertical) { VStack(spacing: 10) { DietListView(valueData: self.$valueData) DietListView(valueData: self.$valueData) .padding() } } .frame(width: 352) } }}struct DietListView: View { @Binding var valueData: [String] var body: some View { VStack { ScrollView { ForEach(self.valueData, id: \.self) { item in NavigationLink(destination: Text("ciao")) { HStack { Text(item) Spacer() Text("100") } .foregroundColor(.primary) .padding(10) } } } .frame(height: 300) } .frame(width: 352, height: 350) .background(Color.white) .cornerRadius(16) .shadow(radius: 10) }}#if DEBUGstruct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() }}#endifAlso, take a look at this: https://stackoverflow.com/a/56498261/1291872EDIT: you can use onDelete, onMove and onInsert only within a List. If you want to let users delete a row in a ScrollView you must implement something yourself. Take a look at the code below for a simple (pretty ugly) example:struct ContentView: View { @State var valueData: [String] = ["Apple", "Pear", "Orange", "Cake"] var body: some View { NavigationView { ScrollView(.vertical) { VStack(spacing: 10) { DietListView(valueData: self.$valueData) DietListView(valueData: self.$valueData) .padding() } } .frame(width: 352) } }}struct DietListView: View { @Binding var valueData: [String] var body: some View { VStack { ScrollView { ForEach(self.valueData.indices, id: \.self) { idx in NavigationLink(destination: Text("ciao")) { HStack { Text(self.valueData[idx]) Spacer() Text("100") .padding(.trailing, 20) Button(action: { self.valueData.remove(at: idx) }) { Image(systemName: "xmark.circle") .resizable() .frame(width: 25, height: 25) .foregroundColor(Color.red) } } .foregroundColor(.primary) .padding([.leading, .trailing], 20) .padding([.top, .bottom], 10) } } } .frame(height: 300) } .frame(width: 352, height: 350) .background(Color.white) .cornerRadius(16) .shadow(radius: 10) }}#if DEBUGstruct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() }}#endif 这篇关于如何在SwiftUI中删除列表选择指示器和分隔符?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 09-17 20:22
