Swift: Complex JSON Model data not properly showing in UITableView - ios

Question

I have a complex JSON (nested values) in it, I properly implemented and data values are in model. But for some unknown reasons its not printing complete data only showing me first 12 values and actually it has 71 data values.
I know I am doing something wrong in adjusting indexPath because of complex data. My model and json are complex(nested) and iterations one.
I need to show tableView data which has specific only like - action type actionType": 101 and title as section in picklist(check json) and textField values in tableView list.
So how can I properly set AppData?.items?[indexPath.row] this for section and for row.
Note: I only need one action type from JSON which is 101 and Title as a tableView Section and textField as list values and these both in pickList. I attached sample small JSON.
Code:
var AppData: SectionList?
let decoder = JSONDecoder()
let response = try decoder.decode(SectionList.self, from: pickResult)
self.AppData = response
TableView:
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return AppData?.items?.count ?? 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = UITableViewCell()
let dic = AppData?.items?[indexPath.row].actionType
return cell
}
Model:
struct SectionList : Codable {
let title : String?
var items : [Item]?
var modified: Bool? = false
}
struct Item : Codable {
let actionType : Int?
let actionUrl : String?
let bgColor : String?
let booleanValue : Bool?
var textField : String?
var textValue : String?
let unitId : Int?
let latitude : Double?
let longitude : Double?
let actionParamData: String?
let actionTitle: String?
let pickList: [SectionList]?
var selection: [Item]?
let multiSelect: Bool?
let selectedValue: [String]?
let version: Int?
let masterId: Int?
let actionId: Int?
let itemValue: String?
var required: Bool? = false
}
Sample JSON:
{
"items": [
{
"actionType": 101,
"version": 3,
"pickList": [
{
"title": "Sayaç yeri seçimi",
"items": [
{
"textField": "Sayaç Yeri Seçiniz",
"itemValue": "0"
},
{
"textField": "Sayaç daire girişinde",
"itemValue": "1"
},
{
"textField": "Sayaç apt. girişinde",
"itemValue": "2"
},
{
"textField": "Sayaç bodrumda",
"itemValue": "3"
},
{
"textField": "Sayaç çatı katında",
"itemValue": "4"
},
{
"textField": "Sayaç bahçede (Müstakil)",
"itemValue": "5"
},
{
"textField": "Sayaç bina dışında",
"itemValue": "6"
},
{
"textField": "Sayaç balkonda",
"itemValue": "7"
},
{
"textField": "Sayaç daire içinde",
"itemValue": "8"
},
{
"textField": "Sayaç istasyon içinde",
"itemValue": "9"
}
]
}
]
},
{
"actionType": 1015,
"version": 3,
"pickList": [
{
"title": "AĞAÇ KURUTMA ÜNİTESİ",
"items": [
]
}
]
},
{
"actionType": 1016,
"version": 3,
"pickList": [
{
"title": "ASTAR FIRINI",
"items": [
]
}
]
}
]
}
Updated Code
var AppData: [Inner]?
let decoder = JSONDecoder()
let response = try decoder.decode(Root.self, from: pickResult)
let res = response.items.filter { $0.actionType == 103 }
self.AppData = res
func numberOfSections(in tableView: UITableView) -> Int {
return AppData?.count ?? 0
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return AppData?[section].pickList[section].title
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return AppData?.count ?? 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = UITableViewCell()
let dic = AppData?[indexPath.section].pickList[indexPath.row].items
print(dic)
let data = dic?[indexPath.row].textField
cell.textLabel?.text = data
return cell
}

Answer 1

You need
struct Root: Codable {
let items: [Inner]
}
struct Inner: Codable {
let actionType, version: Int
let pickList: [PickList]
}
struct PickList: Codable {
let title: String
let items: [PickListItem]
}
struct PickListItem: Codable {
let textField, itemValue: String
}
let decoder = JSONDecoder()
let response = try decoder.decode(Root.self, from: pickResult)
let res = response.items.filter { $0.actionType = 101 }
