How to handle array in model class? - ios

Question

How can make model class for this json data
{
total: 41,
totalPages: 4,
valueData: [
{
id: "23",
lastLogin: "0-Jul-2011 11:27:36 AM",
name: "varii"
},
{
id: "24",
lastLogin: "0-Jul-2015 11:27:36 AM",
name: "sarii"
},
{
id: "25",
lastLogin: "0-Jul-2018 11:27:36 AM",
name: "narii"
} ]
}
class OnResponse {
var total: Int?
var totalPages: Int?
init(response: [String: Any]) {
self.total = response["total"]
self.totalPages = response["totalPages"]
}
}
It's not working how can make it ready for work
and how to pass values to controller to model and how to get value from model

Answer 1

Follow the below class structure
class Response {
var total: Int?
var totalPages: Int?
var valueData: [LoginData]?
init(response: [String: Any]) {
self.total = response["total"]
self.totalPages = response["totalPages"]
var items:[LoginData] = ()
for (data in response["valueData"]) {
let login = LoginData(name: data["name"], lastLogin: data["lastLogin"])
items.append(login)
}
self.valueData = items
}
}
class LoginData {
var name: String?
var lastLogin: String?
init(name: String, lastLogin: String) {
self.name = name
self.lastLogin = lastLogin
}
}

Answer 2

you should use "reverseMatches" to retrieve the array, not the "data". May be you can use a third library to convert your json data to a model, such as Unbox, https://github.com/JohnSundell/Unbox.

Answer 3

Model for Your response :
struct ModelName {
var total: Int?
var totalPage: Int?
var reverseMatches: [LoginDetails]?
}
struct LoginDetails {
var id: String?
var lastLogin: String?
var name: String?
}
Parse the api response and assign the values on the appropriate fields. I have made, all the variables are optional.
Assign values like below.
var obj = Model()
obj.total = response["total"] as? Int
obj should be var, because you are going to mutate the struct values. because struct is value based, not reference based

Answer 4

class DataModel{
var total : Int?
var totalPages : Int?
var valueData : [UserModel]?
init(JSON: [String:Any?]){
self = parser.doParse(JSON: JSON)
}
}
class UserModel{
var id : String?
var lastLogin : String?
var name : String?
}
class parser : NSObject{
class func doParse(JSON: [String:Any?])->DataModel{
let dataModel = DataModel()
dataModel.total = JSON["total"] as? Int
dataModel.totalPages = JSON["totalPages"] as? Int
var userInfo : [UserModel] = []
let valueData : [String:String?]? = JSON["valueData"] as? [String:String?]
if let valueData = valueData{
for dataDict : [String:String?] in valueData{
let itemModel = UserModel()
itemModel.id = dataDict["id"] as? String
itemModel.lastLogin = dataDict["lastLogin"] as? String
itemModel.name = dataDict["name"] as? String
userInfo.append(itemModel)
}
dataModel.valueData = userInfo
}
return dataModel
}
}

Answer 5

class LoginData: NSObject {
let total: Int = 0
let totalPages: Int = 0
let valueData: Array<ValueData> = Array<ValueData>()
override init(total: Int!, totalPages: Int, valueData: Array<ValueData>!) {
self.total = total
self.totalPages = totalPages
self.valueData = valueData
}
}
struct ValueData {
let id: int?
let lastLogin: String?
let name: String?
init(id: int!, lastLogin: string, name: string!)
self.id = id ?? 0
self.lastLogin = lastLogin ?? ""
self.name = name ?? ""
}
}

Answer 6

you should use struct instead of class for creating model object...
advantages of struct over class refer
Why Choose Struct Over Class?
class/24232845
use two struct for holding your data one is for your single total count
and other is for last login detail
struct lastLogin {
let totalCount: (total: Int, totalPages: Int)
let valueArray: [lastLoginDetail]
}
struct lastLoginDetail {
let valueData: (id: String, lastLogin: String,name: String)
}
extension lastLoginDetail {
init(json: [String : String]) throws {
let id = json["id"]
let lastLogin = json["lastLogin"]
let name = json["name"]
let value = (id,lastLogin,name)
self.valueData = value as! (id: String, lastLogin: String, name: String)
}
}
extension lastLogin {
init(json: [String : Any]) throws {
let total = (json["total"] as! NSNumber).intValue
let totalPages = (json["totalPages"] as! NSNumber).intValue
let totalCounts = (total,totalPages)
var userInfo : [lastLoginDetail] = []
// Extract and validate valueData
let valueData = json["valueData"] as? NSArray
if let valueData = valueData{
for dataDict in valueData{
let dic : [String : String] = dataDict as! [String : String]
let lastLoginDeatails = try! lastLoginDetail(json: dic)
userInfo.append(lastLoginDeatails)
}
}
self.valueArray = userInfo
self.totalCount = totalCounts
}
}
func HowToUseModelClass(){
let jsonDic = NSDictionary()
// jsonDic // your json value
let dataValue = try! lastLogin(json: (jsonDic as! [String : Any])) // parsing the data
print(dataValue.totalCount.total)
print(dataValue.totalCount.totalPages)
print(dataValue.valueArray[0].valueData.id)
}
