如何将可映射对象保存到nsuserdefault？

Question

我想将自定义整个对象保存到 NSUserDefault 吗？

这是我的自定义对象..

import UIKit
import ObjectMapper

class SAuthModel: Mappable {

    var status: Int?
    var message: String?
    var result: SResultModel?
    var authToken: String?

    required init?(map: Map) {

    }

    func mapping(map: Map) {
        status       <- map["code"]
        message      <- map["message"]
        authToken    <- map["authToken"]
        result       <- map["data"]
    }
}

class SResultModel: Mappable {

    var name, email, countryCode, mobile, isNotification, promoCode, imageURL, _id, isMobileVerify,otp,faceBookId,googleId,stripeCustId,isProfileSet,created:String?

    required init?(map: Map) {

    }

    func mapping(map: Map) {
        name             <- map["name"]
        email            <- map["email"]
        countryCode      <- map["countryCode"]
        mobile           <- map["mobile"]
        isNotification   <- map["isNotification"]
        promoCode        <- map["promoCode"]
        imageURL         <- map["imageURL"]
        _id              <- map["_id"]
        isMobileVerify   <- map["isMobileVerify"]
        otp              <- map["otp"]
        faceBookId       <- map["faceBookId"]
        googleId         <- map["googleId"]
        stripeCustId     <- map["stripeCustId"]
        isProfileSet     <- map["isProfileSet"]


    }
}

 SAuthService().logInService(parameters:userModel.toJSON()).done{(response) -> Void  in
            SVProgressHUD.dismiss()

            if response.status == 210 {
                guard let responseMessage = response.message else {
                    return
                }
                HHelper.showAlert(responseMessage)
            } else if response.status == 200 {
                USER_DEFAULTS.set(response.result, forKey:ConstantTexts.resultData.localizedString)

                kAppDelegate.pushToHomeViewContoller()
            }
}

我试图将自定义模型对象保存在 USER_DEFAULTS 中，但它不断崩溃。

本文描述了存储到 UserDefaults 的正确方法

var userDefaults = UserDefaults.standard
let encodedData: Data = NSKeyedArchiver.archivedData(withRootObject: teams)
userDefaults.set(encodedData, forKey: "teams")

基本上你必须为其提供一个数据对象...

NSKeyedArchiver 在读取时要求 NSObject 类型。因此上述方法行不通
