To get data the from JSON class is created:
class getData: NSObject {
var descriptionn : String = ""
var image : String = ""
// static let shared = getData()
func getDataForTableView(results: [[String:String]], index : Int){
var productArray = [String:String]()
productArray = results[index]
descriptionn = productArray["description"]!
image = productArray["images"]!
}
}
To display data in table view:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "discoveryNewscell") as! DiscoveryNewsTableViewCell
// if results.count > 0{
classObject.getDataForTableView(results: results, index: indexPath.row)
cell.sneakerImageView.image=filteredsneakernews[indexPath.row].image
print("abc image"+classObject.image)
cell.newsTitle.text = classObject.descriptionn
// }
return cell
}
