Ios 使用NSCoder解码时崩溃
我有两个用于保存数据的模型类,在解码数据时会崩溃 第一类:Ios 使用NSCoder解码时崩溃,ios,swift,nscoder,Ios,Swift,Nscoder,我有两个用于保存数据的模型类,在解码数据时会崩溃 第一类: class User: NSObject,NSCoding, Mappable { var authenticationToken: String? var _id: String? var email: String? var profilePhoto: String? var country: String? var contactNo: String? var occupa
class User: NSObject,NSCoding, Mappable {
var authenticationToken: String?
var _id: String?
var email: String?
var profilePhoto: String?
var country: String?
var contactNo: String?
var occupation: String?
var aboutMe: String?
var role: RollType?
var createdAt: String?
var isActive: Bool?
var avg: Double?
var review: Review?
var subscribe: subscriptionType?
var isPayment: Bool?
var payment: Float?
var invoiceURL: String?
var firstName: String?
var lastName: String?
var password: String?
var pesaPal : [pesaPalData]?
required init?(map: Map) {
super.init()
mapping(map: map)
}
override init() {
super.init()
}
required init(coder aDecoder: NSCoder) {
super.init()
authenticationToken = aDecoder.decodeObject(forKey: "token") as? String
_id = aDecoder.decodeObject(forKey: "_id") as? String
email = aDecoder.decodeObject(forKey: "email") as? String

occupation = aDecoder.decodeObject(forKey: "occupation") as? String
aboutMe = aDecoder.decodeObject(forKey: "aboutMe") as? String
role = RollType(rawValue: (aDecoder.decodeObject(forKey: "role") as! String))
createdAt = aDecoder.decodeObject(forKey: "createdAt") as? String
isActive = aDecoder.decodeObject(forKey: "isActive") as? Bool
subscribe = subscriptionType(rawValue: (aDecoder.decodeObject(forKey: "subscribe") as! String))
invoiceURL = aDecoder.decodeObject(forKey: "invoiceURL") as? String

}
func encode(with aCoder: NSCoder) {
aCoder.encode(authenticationToken, forKey: "token")
aCoder.encode(_id, forKey: "_id")
aCoder.encode(email, forKey: "email")
aCoder.encode(profilePhoto, forKey: "profilePhoto")
aCoder.encode(country, forKey: "country")
aCoder.encode(contactNo, forKey: "contactNo")
aCoder.encode(occupation, forKey: "occupation")
aCoder.encode(aboutMe, forKey: "aboutMe")
aCoder.encode(role?.rawValue, forKey: "role")
aCoder.encode(createdAt, forKey: "createdAt")
aCoder.encode(isActive, forKey: "isActive")
aCoder.encode(subscribe?.rawValue, forKey: "subscribe")
aCoder.encode(isPayment, forKey: "isPayment")
aCoder.encode(payment, forKey: "payment")
aCoder.encode(invoiceURL, forKey: "invoiceURL")
aCoder.encode(firstName, forKey: "firstName")
aCoder.encode(lastName, forKey: "lastName")
aCoder.encode(pesaPal, forKey: "pesaPal")
}
func mapping(map: Map) {
_id <- map["_id"]
email <- map["email"]
profilePhoto <- map["profilePhoto"]
country <- map["country"]
contactNo <- map["contactNo"]
occupation <- map["occupation"]
aboutMe <- map["aboutMe"]
role <- (map["role"],EnumTransform<RollType>())
createdAt <- map["createdAt"]
isActive <- map["isActive"]
review <- map["review"]
avg <- map["avg"]
subscribe <- map["subscribe"]
isPayment <- map["isPayment"]
payment <- map["payment"]
invoiceURL <- map["invoiceURL"]
firstName <- map["firstName"]
lastName <- map["lastName"]
password <- map["password"]
pesaPal <- map["pesapalDetails"]
}
}
第二类:
class pesaPalData: NSObject, Mappable , NSCoding{
var payment1 : String?
var pesapalStatus : String?
var reference : String?
required init?(coder aDecoder: NSCoder) {
payment1 = aDecoder.value(forKey: "paymentPesa") as? String
pesapalStatus = aDecoder.value(forKey: "pesapalStatus") as? String
reference = aDecoder.value(forKey: "reference") as? String
}
required init?(map: Map) {
super.init()
self.mapping(map: map)
}
func encode(with aCoder: NSCoder) {
aCoder.encode(payment1, forKey: "paymentPesa")
aCoder.encode(pesapalStatus, forKey: "pesapalStatus")
aCoder.encode(reference, forKey: "reference")
}
func mapping(map: Map) {
payment1 <- map["payment"]
pesapalStatus <- map["pesapalStatus"]
reference <- map["reference"]
}
}
我在从pespalData类解码时遇到崩溃:
***由于未捕获的异常“NSUnknownKeyException”而终止应用程序,原因:“[valueForUndefinedKey:]:
此类不符合key paymentPesa的键值编码
如果你能帮忙解释是什么导致了这次事故
谢谢你不是在解码器上调用了错误的方法吗?您应该调用decodeObjectforKey:,而不是valueforKey:。在编码和解码过程中,您使用的是密钥paymentPesa 但在映射中,您使用的是支付 可能会这样更改映射:
func mapping(map: Map) {
payment1 <- map["paymentPesa"]
pesapalStatus <- map["pesapalStatus"]
reference <- map["reference"]
}
除此之外,您的代码将无法正常工作,因为您使用了错误的解码API。对于非对象类型,有decodeFloatforKey、DecodeBoolWorkey等。感谢您的建议,我们将对其进行更改
