TextField("Test", text: $name).textFieldStyle(tapflag ? CustomTextFieldStyle1() : CustomTextStyle2())

您最好在样式中使用一些参数并将其绑定到“父”视图
import SwiftUI
struct ContentView: View {
@State private var email = ""
@State private var editing = false
var body: some View {
TextField("Email", text: self.$email, onEditingChanged: { edit in
self.editing = edit
})
.textFieldStyle(MyTextFieldStyle(focused: $editing)).font(.title).border(Color.blue)
}
}
struct MyTextFieldStyle: TextFieldStyle {
@Binding var focused: Bool
func _body(configuration: TextField<Self._Label>) -> some View {
configuration
.padding(10)
.background(
RoundedRectangle(cornerRadius: 10, style: .continuous)
.stroke(focused ? Color.red : Color.gray, lineWidth: 3)
).padding()
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
