I have viewForHeaderInSection in UITableView based on viewForHeaderInSection data each UITableviewCell have UICollectionView in UICollectionViewCell I have to show data for "product" and "qty" the count of each "product" and "qty" is different for each viewForHeaderInSection. I am able to achieve tableview header and cell data but I am not able to get UICollectionViewCell data based on UITableViewHeader data in the json "order_id", "order_unique_id","store_name" and "otp_store" is tableview header section data and "user_details" is tableviewcell data for uicollectionviewcell "product" and "qty"
{
"status": "1",
"error": false,
"data": [
{
"order_id": "11",
"order_unique_id": "ORDR-1001",
"store_name": "24X7",
"otp_store": "781103",
"product": [
"Product One",
"Product Two"
],
"qty": [
"1",
"3"
],
"user_details": {
"name": "Pankaj Ravi",
"number": "0999889",
"landmark": "PBH",
"area": "Bow East",
"pincode": "E3 9EG",
"place": "Home"
},
"status": "2",
"date": "2018-12-13",
"time": "14:37:57"
},
{
"order_id": "1",
"order_unique_id": "ORDR-988",
"store_name": "24X7",
"otp_store": "957505",
"product": [
"Product Eight"
],
"qty": [
"1"
],
"user_details": {
"name": “Jhon”,
"number": “999996",

"place": "Office"
},
"status": "0",

]
}
Code For UITableview
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
print(section)
let headerCell = Bundle.main.loadNibNamed("CustomHeaderCell", owner: self, options: nil)?.first as! CustomHeaderCell
if runnerArray.count > 0 {
headerCell.btnHeader.setTitle("\("x " + runnerArray[section].order_unique_id)", for: UIControl.State.normal)
var status = runnerArray[section].status
if status == "0" {
status = "Pending"
} else if status == "1" {
status = "Dispatch"
} else {
status = "Complete"
}
let lblHeaderText = status + " " + runnerArray[section].time + " , " + runnerArray[section].date
headerCell.lblHeader.text = lblHeaderText
return headerCell
} else {
return UIView()
}
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 40
}
func numberOfSections(in tableView: UITableView) -> Int {
return runnerArray.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 400
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if let cell = tableView.dequeueReusableCell(withIdentifier: "CustomTableViewCell", for: indexPath) as? CustomTableViewCell {
cell.setDataForOTPStoreAndName(runner: runnerArray[indexPath.section])
cell.setDataForProduct(userDetails: userDetailsArray[indexPath.section])
cell.selectionStyle = .none
return cell
}
return UITableViewCell()
}
Code For UICollectionView Cell
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
//Note:- Here i am not able to find how to return array count based on UItableviewheadersection data
return productArray.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
if let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "ProductsCollectionViewCell", for: indexPath) as? ProductsCollectionViewCell {
cell.lblProductName.text = productArray[indexPath.row]
return cell
}
return UICollectionViewCell()
}
you add this code to show number of header and each header add one row,then pass one section object to table cell use below code.
import UIKit
class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {
var dataArry : [DataObj]?
override func viewDidLoad() {
super.viewDidLoad()
if let path = Bundle.main.path(forResource: "response", ofType: "json") {
do {
let data = try Data(contentsOf: URL(fileURLWithPath: path), options: .alwaysMapped)
let jsonObj = try JSONDecoder().decode(Modal.self, from: data)
self.dataArry = jsonObj.data
print("jsonData:\(jsonObj)")
} catch let error {
print("parse error: \(error.localizedDescription)")
}
} else {
print("Invalid filename/path.")
}
}
func numberOfSections(in tableView: UITableView) -> Int {
if let count = self.dataArry?.count {
return count
}
return 0
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "RowCell") as? RowCell
cell?.updateCell(dataObj: self.dataArry?[indexPath.section] ?? DataObj())
return cell!
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let cell = tableView.dequeueReusableCell(withIdentifier: "HeaderCell") as? HeaderCell
cell?.textLabel?.text = dataArry?[section].store_name
return cell
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 60
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 200
}
}
then add this code in your tableview cell class
func updateCell(dataObj:DataObj) {
self.dataObj = dataObj
collectionView.delegate = self
collectionView.dataSource = self
collectionView.reloadData()
}
func numberOfSections(in collectionView: UICollectionView) -> Int {
return 2
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
if section == 0 {
if let count = self.dataObj?.product?.count {
return count
}
}else if section == 1 {
if let count = self.dataObj?.qty?.count {
return count
}
}
return 0
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
if indexPath.section == 0 {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CollectionViewCell", for: indexPath) as? CollectionViewCell
cell?.titlelbl.text = self.dataObj?.product?[indexPath.row]
return cell!
}else if indexPath.section == 1 {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CollectionViewCell", for: indexPath) as?
CollectionViewCell
//cell?.backgroundColor = UIColor.yellow
cell?.titlelbl.text = self.dataObj?.qty?[indexPath.row]
return cell!
}
return UICollectionViewCell()
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
return CGSize(width: 100.0, height: 100.0)
}
}
