Hey all,
I want to fill an UITable with data from a json request. When i create a static table with predefined values i get a response just fine but when i use the json response i get no output in my table. I can print the values just fine so my json request works.
This is my code
struct Todolist: Codable {
let todo: [Todo]
}
struct Todo: Codable {
let id: String
let title: String
let done: String
}
class CompetencesController: UITableViewController {
let cellID = "cellID"
var list = ["I", "Dont", "Get", "It"]
var show: [AnyObject] = []
override func viewDidLoad() {
super.viewDidLoad()
let myUrl = URL(string: "https://gipaa.nl/app/test.php");
var request = URLRequest(url:myUrl!)
request.httpMethod = "POST"// Compose a query string
let accessToken: String? = KeychainWrapper.standard.string(forKey: "token")
let userId: String? = KeychainWrapper.standard.string(forKey: "id")
let postString = "userId=\(userId!)&token=\(accessToken!)";
request.httpBody = postString.data(using: String.Encoding.utf8);
let task = URLSession.shared.dataTask(with: request) { (data: Data?, response: URLResponse?, error: Error?) in
if error != nil
{
print("error=\(error)")
return
}
// You can print out response object
// print("response = \(response)")
//Let's convert response sent from a server side script to a NSDictionary object:
do {
let decoder = JSONDecoder()
let response = try decoder.decode(Todolist.self, from: data!)
let size = response.todo.count
for (index, test) in response.todo.enumerated() {
self.show.append(test.title as AnyObject)
}
print(self.show.count)
print(self.show)
} catch {
print(error)
}
}
task.resume()
view.backgroundColor = .white
tableView.register(UITableViewCell.self, forCellReuseIdentifier: cellID)
}
// Uncomment this block of code to achieve alternating cell colors.
// override func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
// if indexPath.row % 2 == 0 {
// let altCellColor: UIColor? = UIColor(white: 0.7, alpha: 0.5)
// cell.backgroundColor = altCellColor
// }
// }
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.show.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell: UITableViewCell? = tableView.dequeueReusableCell(withIdentifier: cellID)
cell = UITableViewCell(style: .subtitle, reuseIdentifier: cellID)
cell?.selectionStyle = .none
cell?.textLabel?.text = show[indexPath.row] as! String
return cell!
}
override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
if editingStyle == .delete {
self.show.remove(at: indexPath.row)
self.tableView.deleteRows(at: [indexPath], with: .fade)
}
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
// let newVC = NewViewController()
// navigationController?.pushViewController(newVC, animated: true)
let cell = tableView.cellForRow(at: indexPath)
print(cell?.detailTextLabel?.text ?? "")
}
}
When i do
print(self.show.count)
print(self.show)
Printed Response:
6
[Loftdeur, test, test, test, test, test]
when i change to a static array i get my cells outputted.
return list.count
cell?.textLabel?.text = list[indexPath.row] as! String
What am i doing wrong here? Any help would be appriciated
