Question

在我的代码中，当用户进入应用程序时，我给他/她一个令牌，并用UserDefaults保存它，然后在该应用程序中的其他地方，用户可以将地址设置为主地址，然后由UserDefaults保存。当我首先这样做时，它将删除使用用户默认值保存在constantKey.token中的令牌，然后在地址constant.address中放入“ 65”！尽管地址不是“ 65”

UserDefaults.standard.set(self.Main[indexPath.row].AddressLine, forKey: constantAddress.addressLine)

////

UserDefaults.standard.set(self.Main[indexPath.row].ProvinceName, forKey: ConstantsKey.stateName)
UserDefaults.standard.set(self.Main[indexPath.row].ProvinceId, forKey: constantAddress.stateId)
UserDefaults.standard.set(self.Main[indexPath.row].CityName, forKey: constantAddress.cityName)
UserDefaults.standard.set(self.Main[indexPath.row].CityId, forKey: constantAddress.cityId)
UserDefaults.standard.set(self.Main[indexPath.row].AddressLine, forKey: constantAddress.addressLine)
UserDefaults.standard.set(self.Main[indexPath.row].PostalCode, forKey: constantAddress.postalCode)
UserDefaults.standard.set(self.Main[indexPath.row].Tel, forKey: constantAddress.telephone)
UserDefaults.standard.set(self.Main[indexPath.row].Mobile, forKey: constantAddress.mobile)
UserDefaults.standard.set(self.Main[indexPath.row].Id, forKey: constantAddress.Id)



class constantAddress {
    static var Id = ""
    static var stateName = ""
    static var stateId = "0"
    static var cityName = ""
    static var cityId = "0"
    static var addressLine = ""
    static var postalCode = ""
    static var telephone = ""
    static var mobile = ""
}

它不会将项目的值保存到constantAddress

从用户定义中获取数据

StateLbl.text = UserDefaults.standard.string(forKey: constantAddress.stateName)
CityLbl.text = UserDefaults.standard.string(forKey: constantAddress.cityName)
AddressLbl.text = UserDefaults.standard.string(forKey: constantAddress.addressLine)
PostalCodeLbl.text = UserDefaults.standard.string(forKey: constantAddress.postalCode)
TelLbl.text = UserDefaults.standard.string(forKey: constantAddress.telephone)
MobileLbl.text = UserDefaults.standard.string(forKey: constantAddress.mobile)

您使用不同的键来设置UserDefaults并从中获取

UserDefaults.standard.set(self.Main[indexPath.row].ProvinceName, forKey: ConstantsKey.stateName)

使用ConstantsKey.stateName

StateLbl.text = UserDefaults.standard.string(forKey: constantAddress.stateName)

使用constantAddress.stateName

假设ConstantsKey.stateName具有字符串值，那么您需要说的是...

StateLbl.text = UserDefaults.standard.string(forKey: ConstantsKey.stateName)

请仔细阅读UserDefaults的文档…https://developer.apple.com/documentation/foundation/userdefaults

UserDefaults混淆了数据
