无法将自定义对象数组保存到 Swift 4 中的 UserDefault
Not able to save a custom object array save to UserDefault in Swift 4
我在 Google 和 Whosebug 上搜索了大约 2 天，但没有成功。
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，但它总是给我同样的错误。
请帮我解决这个问题。

我尝试使用以下代码将数组转换为数据，但没有成功，我又遇到了另一个错误
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

由于您的联系人是可编码的，您可以利用 JSONEncoder/JSONDecoder 并执行以下操作：
if let json = try? JSONEncoder().encode(contact) {
userDefs?.setValue(json, forKey: "contact");
...
并再次检索联系人：
if let loaded = userDefs?.value(forKey: "contact") as? Data {
let contact2 = try? JSONDecoder().decode(Contact.self, from: loaded)

由于您的联系人是可编码的，您可以利用 JSONEncoder/JSONDecoder 并执行以下操作：
if let json = try? JSONEncoder().encode(contact) {
userDefs?.setValue(json, forKey: "contact");
...
并再次检索联系人：
if let loaded = userDefs?.value(forKey: "contact") as? Data {
let contact2 = try? JSONDecoder().decode(Contact.self, from: loaded)
