Multiple Table View with different arrays - ios

Question

I have a detail view that shows the details of an event, the people who participate and the people who asked to participate. I have created two arrays of different types but they have the same fields, only that a first structure represents the users with the 'status_confirm' field equal to 1 (therefore Accepted Users), while the other has as 'status_confirm' equal to 0 (Users awaiting acceptance). I declared two arrays, the first one: var arrayUserAccepted = [User_accepted] ().
The second one: var arrayUserWaiting = [User_waiting] (). Struct Image
Next step: I populate these structures via a php script
func getData(){
let url = URL(string: “MYURL”)
URLSession.shared.dataTask(with:url!, completionHandler: {(data, response, error) in
guard let data = data, error == nil else { return }
do {
let json = try JSONSerialization.jsonObject(with: data, options: []) as! [String:AnyObject]
print("JSON: \n\(json)\n")
let waiting = json["waiting"] as! [AnyObject]
let accepted = json["accepted"] as! [AnyObject]
DispatchQueue.main.async {
for list_user_waiting in waiting {
let id_user_waiting = list_user_waiting["id_user”] as! String
let name_user_waiting = list_user_waiting[“name_user”] as! String
let email_user_waiting = list_user_waiting["email"] as! String
var photo_user_waiting = list_user_waiting[“photo”]
let status_user_waiting = list_user_waiting["status”] as! String
if photo_user_waiting is NSNull {
photo_user_waiting = ""
}
let listUserWaiting = User_waiting(id_user_waiting: id_user_waiting, name_user_waiting: name_user_waiting, email_user_waiting: email_utente_attesa, foto_waiting: photo_user_waiting as! String, status_waiting: status_user_waiting)
self.arrayUserWaiting.append(listUserWaiting)
self.tableViewListUserWaiting.reloadData()
}
for list_user_accepted in accepted {
let id_user_accepted = list_user_accepted["id_utente"] as! String
let name_user_accepted = list_user_accepted["name_utente"] as! String
let email_user_accepted = list_user_accepted["email"] as! String
var photo_user_accepted = list_user_accepted[“photo"]
let status_user_accepted = list_user_accepted["status”] as! String
if photo_user_accepted is NSNull {
photo_user_accepted = ""
}
let listUserAccepted = User_accepted(id_user: id_user_accepted, nome_utente: name_user_accepted, email: email_user_accepted, foto: photo_user_accepted as! String, stato: status_user_accepted)
self.arrayUserAccepted.append(listUserAccepted)
self.tableViewListUserAccepted.reloadData()
}
}
} catch let error as NSError {
print(error)
}
}).resume()}
This above is a function that I call in the viewDidLoad(). The next step would be to use the functions of the table view and it is here that I think there is the injunction
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
var count: Int?
if tableView == self.tableViewListUserAccepted {
count = arrayUserAccepted.count
}
if tableView == self.tableViewListUserWaiting {
count = arrayUserWaiting.count
}
return count!
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell
if tableView == self.tableViewListUserAccepted {
cell.imageProfileUserAccepted.image = UIImage(named: "imageDefault")
cell.valueSliderUserAccepted.value = Float(50) //JUST FOR POPULATE THE INTERFACE
cell.name_user_accepted.text = arrayUserAccepted[indexPath.row].name_user
}
if tableView == self.tableViewListUserWaiting {
cell.imageProfileUserWaiting.image = UIImage(named: "imageDefault")
cell.valueSliderUserWaiting.value = Float(23) //JUST FOR POPULATE THE INTERFACE
cell.name_user_waiting.text = arrayUserWaiting[indexPath.row].name_user_waiting
}
return cell
}
Once done all this round, I start the application but nothing. The tables are empty. In the console the script answers me correctly and so I can not figure out where the error could be. Needless to say, I have declared the .delegate and .dataSource of both tables, both in the Main.Storyboard and in the code.

Answer 1

Everything is fine just change the format of IF condition and it will work.
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
var count: Int?
if tableView == self.tableViewListUserAccepted {
count = arrayUserAccepted.count
} else {
count = arrayUserWaiting.count
}
return count!
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if tableView == self.tableViewListUserAccepted {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell
cell.imageProfileUserAccepted.image = UIImage(named: "imageDefault")
cell.valueSliderUserAccepted.value = Float(50) //JUST FOR POPULATE THE INTERFACE
cell.name_user_accepted.text = arrayUserAccepted[indexPath.row].name_user
return cell
} else {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell
cell.imageProfileUserWaiting.image = UIImage(named: "imageDefault")
cell.valueSliderUserWaiting.value = Float(23) //JUST FOR POPULATE THE INTERFACE
cell.name_user_waiting.text = arrayUserWaiting[indexPath.row].name_user_waiting
return cell
}
}
Also check if the datasource and delegate of both of your tableView are set. Finally call the tableView.reloadTable() method on both of your tableviews after you populate your arrays in the viewDidLoad() method.
