I was wondering how would I be able to pass down a @FocusState
to another view. Here is some example code:
struct View1: View {
enum Field {
case username, password
}
@State var passwordText: String = ""
@FocusState var focusedField: Field?
var body: some View {
// How would I be able to pass the focusedField here?
View2(text: $passwordText, placeholder: "Password")
//TextField("Password", text: $passwordText)
//.frame(minHeight: 44)
//.padding(.leading, 8)
//.focused($focusedField, equals: .password)
// How would I be able to add the commented code above to View2?
}
}
struct View2: View {
@Binding var text: String
let placeholder: String
var body: some View {
HStack {
TextField(placeholder, text: $text)
.frame(minHeight: 44)
.padding(.leading, 8)
// How would I be able to add this
//.focused(binding: , equals: )
if text.count > 0 {
Image(systemName: "xmark.circle.fill")
.font(.headline)
.foregroundColor(.secondary)
.padding(.trailing, 8)
}
}
}
}
How would I be able to pass it down to View2
?
Or is there a better way to reuse a custom text field?
You can pass its binding as argument, like
struct View1: View {
enum Field {
case username, password
}
@State var passwordText: String = ""
@FocusState var focusedField: Field?
var body: some View {
View2(text: $passwordText, placeholder: "Password", focused: $focusedField)
}
}
struct View2: View {
@Binding var text: String
let placeholder: String
var focused: FocusState<View1.Field?>.Binding // << here !!
var body: some View {
HStack {
TextField(placeholder, text: $text)
.frame(minHeight: 44)
.padding(.leading, 8)
.focused(focused, equals: .password) // << here !!
if text.count > 0 {
Image(systemName: "xmark.circle.fill")
.font(.headline)
.foregroundColor(.secondary)
.padding(.trailing, 8)
}
}
}
}
