How to show array of array json in tableview using Swift? - ios

Question

Now my ViewController code is here -
import UIKit
struct jsonstruct: Codable {
let name: String
let meta_data: [Categories]
enum CodingKeys: String, CodingKey {
case name
case meta_data
}
}
struct Categories: Codable {
let value: String
enum CodingKeys: String, CodingKey {
case value
}
}
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var tableView: UITableView!
var arrdata : [jsonstruct] = [jsonstruct]()
var categorydata : [Categories] = [Categories]()
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
getdata()
}
func getdata() {
let url = URL(string: "https://mywebstaging.net/ab/garnier/wp-json/wc/v3/products?consumer_key=<key>&consumer_secret=<secret>")
URLSession.shared.dataTask(with: url!) { (data, response, error) in
do{if error == nil{
self.arrdata = try JSONDecoder().decode([jsonstruct].self, from: data!)
print(self.arrdata)
DispatchQueue.main.async {
self.tableView.reloadData()
}
}catch{
print("Error in get json data")
}
}.resume()
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if tableView == tableView {
return arrdata.count
}else{
return categorydata.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if tableView == tableView {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CellTableViewCell
let getdata = arrdata[indexPath.row]
cell.lblid.text = getdata.name
return cell
}
else{
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CellTableViewCell
let getdatadesciption = self.categorydata[indexPath.row]
cell.lblname.text = getdatadesciption.value
return cell
}
}
}
Hare only the "name" is being displayed in the tableview. But the "value" is not coming. The output I'm getting like this. Please guide me. Thanks in advance.

Answer 1

Replace
if tableView == tableView {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CellTableViewCell
let getdata = arrdata[indexPath.row]
cell.lblid.text = getdata.name
return cell
}
else{
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CellTableViewCell
let getdatadesciption = self.categorydata[indexPath.row]
cell.lblname.text = getdatadesciption.value
return cell
}
with getdata.meta_data.first?.value contains top category name
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CellTableViewCell
let getdata = arrdata[indexPath.row]
cell.lblid.text = getdata.name
cell.lblname.text = getdata.meta_data.first?.value
return cell
You don't have to maintain 2 arrays it's only one

Replace
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if tableView == tableView {
return arrdata.count
} else {
return categorydata.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if tableView == tableView {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CellTableViewCell
let getdata = arrdata[indexPath.row]
cell.lblid.text = getdata.name
return cell
} else {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CellTableViewCell
let getdatadesciption = self.categorydata[indexPath.row]
cell.lblname.text = getdatadesciption.value
return cell
}
}
With
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return arrdata.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CellTableViewCell
let data = arrdata[indexPath.row]
let category = data.meta_data.first
cell.lblid.text = data.name
cell.lblname.text = category.value
return cell
}
