无法在 Swift 4 中将自定义对象数组保存到 UserDefault

Question

我在 Google 和 StackOverflow 上搜索了大约 2 天，但没有运气。

我的自定义对象几乎是CNContact 对象的复制品。

struct Contact: Codable {

let fullName, phones, emails: String
let imageDataAvailable, expanded: Bool
let thumbnailImageData, imageData: Data
let contactType: Int
let identifier: String
let namePrifix, givenName, middleName, familyName, previousFamilyName, nameSuffix, nickName, organizationName, departmentName, jobTitle, phoneticGivenName, phoneticMiddleName, phoneticFamilyName, phoneticOrganizationName, note: String
let birthday, nonGregorianBirthday: DateComponents
let dates: [ContactDate]
let postalAddresses: [PostalAddress]
let urlAddresses: [UrlAddress]
let contactRelations: [ContactRelation]
let socialProfiles: [SocialProfile]
let instantMessageAddresses: [InstantMessageAddress]
let phoneNumbers: [PhoneNumber]
let emailAddresses: [Email]
}

struct PostalAddress: Codable {
    let label, street, subLocality, city, subAdministativeArea, state, postalCode, country, isoCountryCode: String
}

struct UrlAddress: Codable {
    let label, value: String
}

struct ContactRelation: Codable {
    let label, name: String
}

struct SocialProfile: Codable {
    let label, urlString, userName, userIdentifier, service: String
}

struct PhoneNumber: Codable {
    let label, stringValue: String
}

struct Email: Codable {
    let label, value: String
}

struct InstantMessageAddress: Codable {
    let label, userName, service: String
}

struct ContactDate: Codable {
    let label: String
    let value: DateComponents
}

我尝试将Contact 对象的数组保存到UserDefault，但它一直给我同样的错误。

请帮我解决这个问题。

我尝试使用下面的代码将数组转换为数据，但运气不好，我又遇到了一个错误

代码

do {
        let contactJson = try JSONSerialization.data(withJSONObject: arrContact, options: .prettyPrinted)
        CommonFunctions.setUserDefaultValue(key: WSKey.contacts.rawValue, value: contactJson)
    } catch let parsingError {
        print("Error", parsingError)
    }

错误

由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“JSON 写入中的类型无效 (_SwiftValue)”

我在日志中带有debugDescription 命令的数组如下

Answer 1

由于您的联系人是可编码的，您可以使用 JSONEncoder/JSONDecoder 并执行以下操作：

if let json = try? JSONEncoder().encode(contact) {
    userDefs?.setValue(json, forKey: "contact");
    ...

然后再次检索联系人：

 if let loaded = userDefs?.value(forKey: "contact") as? Data {
     let contact2 = try? JSONDecoder().decode(Contact.self, from: loaded)
      ...
