CollectionView in TableView Cell Swift4 - tableview

Question

I created a collectionView inside the tableView and I took the data in JSON. In each tableview cell there are arrays for collectionviewcell which vary in number but the same collectionviewcell appears.
Here is my code:
Class ViewController.swift
import UIKit
struct ModelPurchaseRequest {
var year: String
var type: String
var listFlowStatus: [String]
var listFlowPosition: [String]
init(year: String, type: String, listFlowStatus: [String], listFlowPosition: [String]) {
self.year = year
self.type = type
self.listFlowStatus = listFlowStatus
self.listFlowPosition = listFlowPosition
}
}
var listFlowStatus = [String]()
var listFlagPosition = [String]()
var modelPurchase = [ModelPurchaseRequest]()
class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {
#IBOutlet var tableView: UITableView!
var flowStatus = ""
var flagPosition = ""
var purYear = ""
var purType = ""
override func viewDidLoad() {
super.viewDidLoad()
getDataPurchaseRequest()
}
func getDataPurchaseRequest() {
let url = URL(string: "https://xxxxxxxxxxxxxx")
URLSession.shared.dataTask(with: url!) { (data, response, error) in
if error != nil {
print("Get list purchase request error")
return
}
print(response!)
guard data != nil else {return}
do {
modelPurchase.removeAll()
let json = try JSONSerialization.jsonObject(with: data!, options: []) as! [String: Any]
print(json)
let statusRespon = json["status"] as! Bool
print("Purchase Request - Response status: \(statusRespon)")
if statusRespon == true {
guard let isiData = json["data"] as? [[String: Any]] else {
print("Purchase Request - data is empty")
return
}
for dataIsi in isiData {
guard let listData = dataIsi["list_data"] as? [[String: Any]] else {
print("Purchase Request - list data purchase request is empty")
return
}
for dataList in listData {
if ((dataList["year"] as? NSNull) != nil) {
self.purYear = "-"
}else{
self.purYear = dataList["year"] as! String
}
if ((dataList["tipe"] as? NSNull) != nil) {
self.purType = "-"
}else{
self.purType = dataList["tipe"] as! String
}
// get flow array
guard let flowList = dataList["flow"] as? [[String: Any]] else {
print("Get flow PR is empty")
return
}
listFlowStatus.removeAll()
listFlagPosition.removeAll()
for listFlow in flowList {
self.flowStatus = listFlow["flow_status"] as! String
self.flagPosition = listFlow["flag_position"] as! String
print("=== Flow \(self.flowId) - \(self.flagPosition) ===")
listFlowStatus.append(self.flowStatus)
listFlagPosition.append(self.flagPosition)
}
modelPurchase.append(ModelPurchaseRequest(year: self.purYear, type: self.purType, listFlowSatus: listFlowStatus, listFlowPosition: listFlagPosition))
}
}
DispatchQueue.main.async {
self.tableView.reloadData()
}
}else{
print("Get list purchase request response status false")
}
}catch{
print(error.localizedDescription)
}
}.resume()
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return modelPurchase.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell
cell.collectionView.reloadData()
return cell
}
}
Class CollectionViewCell.swift
import UIKit
class CollectionViewCell: UICollectionViewCell {
#IBOutlet weak var view: UIView!
}
Class TableViewCell.swift
import UIKit
class TableViewCell: UITableViewCell,UICollectionViewDelegate,UICollectionViewDataSource {
#IBOutlet weak var collectionView: UICollectionView!
override func awakeFromNib() {
super.awakeFromNib()
collectionView.dataSource = self as UICollectionViewDataSource
collectionView.delegate = self as UICollectionViewDelegate
collectionView.reloadData()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return modelPurchase[section].listFlowStatus.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath) as! CollectionViewCell
let positionNow = modelPurchase[indexPath.section].listFlowPosition[indexPath.row]
if positionNow == "Green" {
cell.view.backgroundColor = UIColor.green
}else if positionNow == "Orange" {
cell.view.backgroundColor = UIColor.orange
}else{
cell.view.backgroundColor = UIColor.red
}
return cell
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
print(modelPurchase[indexPath.section].listFlowPosition[indexPath.row])
}
}
Here JSON:
{
"status": true,
"message": "Data Show Success",
"data": [
{
"list_data": [
{
"rowsnum": "1",
"year": "2018",
"tipe": "PROGRAM",

Answer 1

Please change the code as following :
Step 1:
In tableView cellForRowAt method please write:
cell.collectionView.tag = indexPath.row
Step2:
Then in collectionView numberOfItemsInSection method please write :
return modelPurchase[collectionView.tag].listFlowStatus.count
Step 3:
In collectionView cellForItemAt method write :
let positionNow = modelPurchase[collectionView.tag].listFlowPosition[indexPath.row]
Change the code accordingly.It may helps to you .Thank you
