passing values from uitableview to uicollectionview - ios

Question

How can I pass parsed values from a url which has been used in an UITableview to a UICollectionview(scrolled horizontally) which has been used in each of the UITableviews cell? I want do this in swift language.
I am using a model with the name "collectionCat".
import Foundation
public class CollectionCat{
var brandid:String = ""
var brandname:String = ""
var result:String = ""
var noitems:String = ""
}
I am also using Alamofire to parse data from url.
override func viewDidLoad() {
super.viewDidLoad()
self.startActivityAnimating(message: "", type: NVActivityIndicatorType.BallClipRotate, color: AppColor.AppRed, padding: 10)
Alamofire.request(.POST, "http://goringr.co.in/Mathrubhumi_project_ios/brand.php", parameters: ["": ""])
.validate()
.responseJSON { response in
switch response.result {
case .Success:
print("Validation Successful")
self.jsonResultParse(response.result.value!)
self.stopActivityAnimating()
case .Failure(let error):
print(error)
self.stopActivityAnimating()
// return userCatagory
}
}
// Do any additional setup after loading the view.
}
if JSONArray.count != 0 {
//_ = [UserCatagory]()
for i:Int in 0 ..< JSONArray.count {
let jObject = JSONArray[i] as! NSDictionary
let uCollect:CollectionCat = CollectionCat()
uCollect.brandid = (jObject["brandid"] as AnyObject? as? String) ?? ""
uCollect.brandname = (jObject["brandname"] as AnyObject? as? String) ?? ""
uCollect.result = (jObject["result"] as AnyObject? as? String) ?? ""
uCollect.noitems = (jObject["noitems"] as AnyObject? as? String) ?? ""
collect.append(uCollect)
print("collect COUNT ",collect.count)
}
self.newTable.reloadData()
}
}
What i dont know is how to transfer the stored data to UICollection view which is in each cell of the mentioned UITableview.
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
// collectMaster = collect[indexPath.row]
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! SecondHomeViewCell
// collectMaster = CollectionCat()
cell.get = ????
return cell
}
Can anyone Please help me with this?
The SecondHomeViewCell's code goes like this.
import UIKit
import Kingfisher
import Alamofire
import NVActivityIndicatorView
class SecondHomeViewCell: UITableViewCell{
#IBOutlet weak var collectionView: UICollectionView!
var genre:CollectionCat? = nil{
didSet {
collectionView.reloadData()
}
}
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
//return genre!.brandid
// return genre
return 1
}
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("secondHome", forIndexPath: indexPath) as! SecondHomeCollectionViewCell
if let genre = genre {
cell.genre = genre.brandid[indexPath.row]
}
return cell
}
func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
let itemsPerRow:CGFloat = 4
let hardCodedPadding:CGFloat = 5
let itemWidth = (collectionView.bounds.width / itemsPerRow) - hardCodedPadding
let itemHeight = collectionView.bounds.height - (2 * hardCodedPadding)
return CGSize(width: itemWidth, height: itemHeight)
}
}

Answer 1

Add a array in your ViewController, call it
var collCat = [CollectionCat]()
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let collectMaster = collCat[indexPath.row]
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! SecondHomeViewCell
cell.brandID = collectMaster.brandid
//and so on
return cell
}
If this is not the answer you are looking for, please tell me. Because I wanted to clarify but I don't have the ability to comment yet. I need to reach 50 reputation to be able to comment and ask some clarifications.

You can pass data to collection view by creating function in UITableviewCell custom class
class SecondHomeViewCell: UITableViewCell{
//Array containing modals for particular tableview cell index path
var arrDataFromViewController = NSArray()
func getData(arrData:NSArray){
arrDataFromViewController = arrData
collectionView.delegate = self
collectionView.dataSource = self
collectionView.reloadData()
}
#IBOutlet weak var collectionView: UICollectionView!
var genre:CollectionCat? = nil{
didSet {
collectionView.reloadData()
}
}
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
//return genre!.brandid
// return genre
return 1
}
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("secondHome", forIndexPath: indexPath) as! SecondHomeCollectionViewCell
if let genre = genre {
cell.genre = genre.brandid[indexPath.row]
}
return cell
}
func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
let itemsPerRow:CGFloat = 4
let hardCodedPadding:CGFloat = 5
let itemWidth = (collectionView.bounds.width / itemsPerRow) - hardCodedPadding
let itemHeight = collectionView.bounds.height - (2 * hardCodedPadding)
return CGSize(width: itemWidth, height: itemHeight)
}
}
//Now in tableview data source method
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
// collectMaster = collect[indexPath.row]
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! SecondHomeViewCell
// collectMaster = CollectionCat()
cell.getData = yourArray[indexPath.row]//Get Array data
return cell
}
