Swift:使用枚举的原始值来访问常量数组中的UIButton和字符串是个好主意吗？

enum ButtonType: String {
    case login
    case signUp
    case forgotPassword
}

let loginButton = UIButton()
loginButton.tag = ButtonType.login.rawValue

let signUpButton = UIButton()
signUpButton.tag = ButtonType.signUp.rawValue

let forgotPasswordButton = UIButton()
forgotPasswordButton.tag = ButtonType.forgotPassword.rawValue

enum StringIdentifier: String {
    case welcomeMessage
    case errorMessage
    case successMessage
}

let welcomeMessage = "Welcome!"
let errorMessage = "An error occurred."
let successMessage = "Operation successful."

let message = StringIdentifier.errorMessage.rawValue
