UICollectionView in UITableView - I want to show data in CollectionVewCell - arrays

Question

I want to show data in UICollectionView. Which is coming from UITableView cell. My main concern is this. I am passing a key catgID from cellForRowAt in another API and getting data from it. But data is not coming proper way.
I am passing catgID from cellForRowAt and getting in another API which will show the list of data for UICollectionViewCells. Now data is coming but not in proper way.
This is my UITableView class for tableview index.
import UIKit
import Reachability
import Alamofire
var arrayMenuProducts = [structMenuProducts]()
struct structMenuProducts {
var id:Int
var product_name:String
var category:String
var product_image:String
var price:String
var unit_price:Double
var addons:NSArray
}
class MenuVC: UIViewController, UITableViewDelegate, UITableViewDataSource {
var reachability = Reachability()!
#IBOutlet weak var tableview: UITableView!
var arrayMenuCat = [structMenuCat]()
struct structMenuCat{
var id:Int
var category_name:String
}
override func viewDidLoad() {
super.viewDidLoad()
menuVegAPI()
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return arrayMenuCat.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
catgID = arrayMenuCat[indexPath.row].id
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell1") as! MenuTableCell
cell.lblCategoryTitle.text = arrayMenuCat[indexPath.row].category_name
cell.collectionviewOne.reloadData()
// let catid = arrayMenuCat[indexPath.row].id
// print(catid)
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 216
}
func menuVegAPI()
{
if (reachability.connection == .wifi) || (reachability.connection == .cellular)
{
arrayMenuCat.removeAll()
SwiftLoader.show(animated: true)
let url = BaseUrl + ViewController.sharedInstance.menuCategory
print(url)
Alamofire.request(url, method: .get, parameters: nil, encoding: URLEncoding.default).responseJSON { response in
SwiftLoader.hide()
switch response.result {
case .success:
let json = response.result.value
print(json)
let code = (json as AnyObject).object(forKey: "code") as! Int
print(code)
if code == 200
{
let data = (json as AnyObject).object(forKey: "data") as? NSArray
for alldata in data!
{
let id = (alldata as AnyObject).object(forKey: "id") as! Int
let category_name = (alldata as AnyObject).object(forKey: "category_name") as! String
let arr = structMenuCat(id: id, category_name: category_name)
self.arrayMenuCat.append(arr)
// self.menuProductsAPI(categoryid: id)
}
self.tableview.reloadData()
}
else
{
}
case .failure:
print("error")
}
}
}
else
{
alert(title: "", message: "Please Check Your Internet Connection")
}
}
}
This is my TableViewCell type class. In this class I am show data on CollectionView. Its code is here
import UIKit
import Alamofire
import Reachability
var catgID : Int!
var collectionreload : UICollectionView?
class MenuTableCell: UITableViewCell, UICollectionViewDataSource, UICollectionViewDelegate {
var reachability = Reachability()!
#IBOutlet weak var lblCategoryTitle: UILabel!
#IBOutlet weak var collectionviewOne: UICollectionView!
var arrayMenuProducts = [structMenuProducts]()
struct structMenuProducts {
var id:Int
var product_name:String
var category:String
var product_image:String
var price:String
var unit_price:Double
var addons:NSArray
}
override func awakeFromNib() {
super.awakeFromNib()
collectionreload = self.collectionviewOne
print(arrayMenuProducts)
print(catgID ?? 0)
menuProductsAPI(categoryid: catgID!)
}
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 arrayMenuProducts.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CellRID", for: indexPath) as! MenuCollectionViewCell
let abc = arrayMenuProducts[indexPath.row].product_name
print(abc)
// if catgID == Int(arrayMenuProducts[indexPath.row].category)
// {
cell.lblTitleForVeg.text = arrayMenuProducts[indexPath.row].product_name
cell.lblForPriceVeg.text = "$\(arrayMenuProducts[indexPath.row].unit_price)"
}
func menuProductsAPI(categoryid:Int)
{
if (reachability.connection == .wifi) || (reachability.connection == .cellular)
{
SwiftLoader.show(animated: true)
arrayMenuProducts.removeAll()
let url = BaseUrl + ViewController.sharedInstance.menuProducts + "categoryid=\(categoryid)"
print(url)
Alamofire.request(url, method: .get, parameters: nil, encoding: JSONEncoding.default).responseJSON { response in
switch response.result {
case .success:
let json = response.result.value
print(json)
// self.tableview.reloadData()
let code = (json as AnyObject).object(forKey: "code") as! Int
print(code)
if code == 200
{
let data = (json as AnyObject).object(forKey: "data") as? NSArray
DispatchQueue.main.async {
for alldata in data!
{
let id = (alldata as AnyObject).object(forKey: "id") as! Int
let product_name = (alldata as AnyObject).object(forKey: "product_name") as! String
let category = (alldata as AnyObject).object(forKey: "category") as! String
let product_image = (alldata as AnyObject).object(forKey: "product_image") as! String
let price = (alldata as AnyObject).object(forKey: "price") as! String
let unit_price = (alldata as AnyObject).object(forKey: "unit_price") as! Double
let addons = (alldata as AnyObject).object(forKey: "addons") as? NSArray
let arr = structMenuProducts(id: id, product_name: product_name, category: category, product_image: product_image, price: price, unit_price: unit_price, addons: addons!)
self.arrayMenuProducts.append(arr)
}
self.collectionviewOne.reloadData()
SwiftLoader.hide()
}
}
else
{
}
case .failure:
print("error")
}
}
}
else
{
// alert(title: "", message: "Please Check Your Internet Connection")
}
}
}
I want to show data coming in CollectionView in a proper formate. If Tableview index == 0 and Category id is coming 10 then. Category id 10 will first then one by one in a sequence I want to pass category id. In my case Category id is not coming in a queue.

Answer 1

Update the tableview datasource method as
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell1") as! MenuTableCell
cell.lblCategoryTitle.text = arrayMenuCat[indexPath.row].category_name
cell.menuProductsAPI(categoryid: arrayMenuCat[indexPath.row].id)
return cell
}
And remove menuProductsAPI(categoryid: catgID!) from awakeFromNib method
