I am running into a problem where I cannot find a solution and searching the web also doesn't help me.
The problem is pretty simple. I know how to make use of TableViews and also how to make use of the numberOfSections function.
The Problem now is, that I am retrieving Data from Firebase Database as an Array of Objects.
Here it is members = [PaymentTeam]() where the class looks like this:
class PaymentTeam {
var key: String?
let memberJob: String?
let memberName: String?
let memberID:String?
let projectCreated:String?
let projectName: String?
let confirmedBool: Bool?
let paidBool: Bool?
init(memberJob: String, memberName: String, memberID:String, confirmedBool: Bool, paidBool: Bool, projectCreated:String, projectName: String) {
self.memberName = memberName
self.memberJob = memberJob
self.memberID = memberID
self.projectCreated = projectCreated
self.confirmedBool = confirmedBool
self.paidBool = paidBool
self.projectName = projectName
}
var dictValue: [String: Any] {
return ["memberName" : memberName as Any,
"memberJob" : memberJob as Any,
"memberID": memberID as Any,
"projectCreated": projectCreated as Any,
"confirmedBool": confirmedBool as Any,
"paidBool": paidBool as Any,
"projectName": projectName as Any
]
}
init?(snapshot: DataSnapshot) {
guard let dict = snapshot.value as? NSDictionary,
let memberJob = dict["memberJob"] as? String,
let memberName = dict["memberName"] as? String,
let projectCreated = dict["projectCreated"] as? String,
let projectName = dict["projectName"] as? String,
let memberID = dict["memberID"] as? String,
let confirmedBool = dict["confirmedBool"] as? Bool,
let paidBool = dict["paidBool"] as? Bool
else {return nil}
self.memberJob = memberJob
self.memberName = memberName
self.projectCreated = projectCreated
self.projectName = projectName
self.memberID = memberID
self.confirmedBool = confirmedBool
self.paidBool = paidBool
}
}
and retrieving is done like this:
static func chosenTeam(for user: User, completion: @escaping ([PaymentTeam]) -> Void) {
let ref = Database.database().reference().child("selectedTeams").child(User.current.uid)
ref.observe(DataEventType.value, with: { (snapshot) in
guard let snapshot = snapshot.children.allObjects as? [DataSnapshot] else {
return completion([])
}
let chosenTeam = snapshot.reversed().compactMap(PaymentTeam.init)
completion(chosenTeam)
})
}
The problem now is, that with:
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return members[section].count
}
I get the error message: Value of type 'PaymentTeam' has no member 'count' and I can only choose between the different class members like members.memberID
For the function:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let member = members[indexPath.section][indexPath.row]
let cell = tableView.dequeueReusableCell(withIdentifier: "ChosenTeamNameTableViewCell") as! ChosenTeamNameTableViewCell
cell.memberNameLabel.text = member.memberName
return cell
}
I get following error message:
Value of type 'PaymentTeam' has no subscripts
Whereby [indexPath.section]is underlined.
Maybe someone can help me to figure out how to structure my Firebase Data in that membersArray to actually make use of numberofSections
Here is the whole code for the ViewController with the Tableview:
class PaymentHomeViewController: UIViewController {
@IBOutlet weak var tableView: UITableView!
@IBOutlet weak var headerSeperator: UIView!
var members = [PaymentTeam]()
override func viewDidLoad() {
super.viewDidLoad()
setUpUI()
UserService.chosenTeam(for: User.current) { (chosenTeam) in
self.members = chosenTeam
for value in self.members {
self.projectTitles.append(value.projectName ?? "Error")
}
self.tableView.reloadData()
}
}
func setUpUI() {
Utilities.addShadowtoView(headerSeperator)
}
extension PaymentHomeViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let label = UILabel()
label.text = "Header"
label.backgroundColor = UIColor.lightGray
}
func numberOfSections(in tableView: UITableView) -> Int {
return members.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return members[section].count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let member = members[indexPath.section][indexPath.row]
let cell = tableView.dequeueReusableCell(withIdentifier: "ChosenTeamNameTableViewCell") as! ChosenTeamNameTableViewCell
cell.memberNameLabel.text = member.memberName
return cell
}
}
// MARK: - UITableViewDelegate
extension PaymentHomeViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 78
}
}
Thanks for your help in advance. :)
