I have a list with textField and a button.
my goal is that I want to provide default value to textField when I toggle the button.
I can do it with text, but I don't know how to do with textField
struct ContentView: View {
@State var isEnableBatch: Bool = false
var body: some View {
VStack {
Button {
isEnableBatch.toggle()
} label: {
Image(isEnableBatch == true ? "EAIcon-Check_rectangle" : "EAIcon-Check_Box")
}
List {
ForEach(0 ..< 10, id: \.self) { index in
let value = isEnableBatch ? "batch Enable" : "\(index)"
Text(value) // <-- I don't know how to do here if i change to textField
}
}
.listStyle(.plain)
}
.padding()
}
}
If I change to use textField as below
it will show compile error No exact matches in reference to static method 'buildExpression'
struct ContentView: View {
@State var isEnableBatch: Bool = false
@State var attValue: String = ""
var body: some View {
VStack {
Button {
isEnableBatch.toggle()
} label: {
Image(isEnableBatch == true ? "EAIcon-Check_rectangle" : "EAIcon-Check_Box")
}
List {
ForEach(0 ..< 10, id: \.self) { index in
attValue = isEnableBatch ? "batch Enable" : "\(index)" // <-- how to update TextField's default value ??
TextField("", text: $attValue)
}
}
.listStyle(.plain)
}
.padding()
}
}
