如何确定在 SwiftUI 中更改了哪个文本字段

Question

我的代码中显示了以下 2 个文本字段我的问题是如何区分正在更改的文本字段

TextField("", text: $phoneAuthViewModel.firstCodeField)
    .frame(width:40, height: 48, alignment: .center)
     .background(Color(red: 1, green: 1, blue: 1, opacity: 0.3))
     .foregroundColor(.black)
     .cornerRadius(5)
     .keyboardType(.phonePad)
     .accentColor(.white)
     .multilineTextAlignment(.center)
     .onChange(of: phoneAuthViewModel.firstCodeField, perform: editingChanged(_:))


TextField("", text: $phoneAuthViewModel.country)
    .frame(width:40, height: 48, alignment: .center)
     .background(Color(red: 1, green: 1, blue: 1, opacity: 0.3))
     .foregroundColor(.black)
     .cornerRadius(5)
     .keyboardType(.phonePad)
     .accentColor(.white)
     .multilineTextAlignment(.center)
     .onChange(of: phoneAuthViewModel.country, perform: editingChanged(_:))

func editingChanged(_ value: String) {
   
    
}

现在我如何确定正在编辑哪个文本字段。是否可以通过 editingChanged Function

传递一个协议

Answer 1

只需使用不同的函数作为回调，例如

TextField("", text: $phoneAuthViewModel.firstCodeField)
     .onChange(of: phoneAuthViewModel.firstCodeField, perform: codeChanged(_:))


TextField("", text: $phoneAuthViewModel.country)
     .onChange(of: phoneAuthViewModel.country, perform: countryChanged(_:))

func codeChanged(_ value: String) {
  // handle code changed here
}

func countryChanged(_ value: String) {
  // handle country changed here
}
