Fetch data from Firebase Database to tableview - ios

Question

First I get these values into my Firebase Database, which works successfully.
func handleSale() {
let ref = FIRDatabase.database().reference().child("tickets")
let childRef = ref.childByAutoId()
guard let Price = emailTextField.text, ticketName = passwordTextField.text else {
print("Form is not valid")
return
}
let values: [String: AnyObject] = ["Price": Price, "ticketName": ticketName]
ref.observeEventType(.ChildAdded, withBlock: { (snapshot) in
let ticketId = snapshot.key
let ticksRef = FIRDatabase.database().reference().child("tickets").child(ticketId)
ticksRef.observeSingleEventOfType(.Value, withBlock: { (snapshot) in
guard let dictionary = snapshot.value as? [String: AnyObject] else {
return
}
self.messages.append(Ticket(dictionary: dictionary))
childRef.updateChildValues(values) { (error, ref) in
if error != nil {
print(error)
return
}
print(snapshot)
print(dictionary)
print(ticketId)
}
}, withCancelBlock: nil)
})
}
I then tried to setup a tableview with a custom cell class and fetch these values into the tableview, however being fairly new to swift, I know I haven't done this correctly. In the end I would like that my values "price" and "ticketName" shows up in my table's..
here is my tableview:
import UIKit
import Firebase
class Sales: UITableViewController {
let cellId = "cellId"
var messages = [Ticket]()
var messagesDictionary = [String: Ticket]()
override func viewDidLoad() {
super.viewDidLoad()
var messages = [Ticket]()
var messagesDictionary = [String: Ticket]()
navigationItem.leftBarButtonItem = UIBarButtonItem(title: "Logout", style: .Plain, target: self, action: #selector(heya))
tableView.registerClass(FredericCell.self, forCellReuseIdentifier: cellId)
func fetchTicket() {
FIRDatabase.database().reference().child("tickets").observeEventType(.ChildAdded, withBlock: { (snapshot) in
if let dictionary = snapshot.value as? [String: AnyObject] {
let ticketId = snapshot.key
Ticket.setValuesForKeysWithDictionary(dictionary)
return
}
}, withCancelBlock: nil)
}
print("test to see if it works")
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 5
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(cellId, forIndexPath: indexPath) as! FredericCell
return cell
}
func heya() {
print ("working")
}
I have edited in hope of filling out my cells, but without luck..:
override func tableView(tableView: UITableView,
numberOfRowsInSection section: Int) -> Int {
return tickets
.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(cellId, forIndexPath: indexPath) as! FredericCell
let ticket = tickets[indexPath.row]
cell.textLabel?.text = ticket.ticketName
cell.detailTextLabel?.text = ticket.Price
dispatch_async(dispatch_get_main_queue(), {
self.tableView.reloadData()
})
return cell
}
