How to filter array from selected tableviewcell in swift? - ios

Question

I am quite puzzled on how will I construct my codes regarding on how I will filter the selected array from a tableviewcell. The JSON below is the content of the tableview which displays like
[
{
"hospitalNumber": "00000001",
"patientName": "Test Patient",
"totalAmount": 1111.3
},
{
"hospitalNumber": "00000002",
"patientName": "Test Patient 2",
"totalAmount": 1312
},
{
"hospitalNumber": "00000003",
"patientName": "Test Patient 3",
"totalAmount": 475
}
]
The problem is how can I display the selected hospitalNumber and patientName in the next View Controller, which will display like
This is what my `PaymentDetailsViewController' have:
var patientList: [Patient]! {
didSet {
latestCreditedAmountTableView.reloadData()
}
}
override func viewDidLoad() {
super.viewDidLoad()
getPatientList()
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "showPatientPaymentDetailsVC" {
if let patientPaymentDetailsVC = segue.destination as? PatientPaymentDetailsViewController {
patientPaymentDetailsVC.isBrowseAll = self.isBrowseAll
if !isBrowseAll {
patientPaymentDetailsVC.patientPayoutDetails = self.selectedPatientPayment
patientPaymentDetailsVC.currentRemittance = self.currentRemittance
patientPaymentDetailsVC.doctorNumber = self.doctorNumber
}
}
}
}
func getPatientList() {
SVProgressHUD.setDefaultMaskType(.black)
SVProgressHUD.show(withStatus: "Retrieving Patient List")
APIService.PatientList.getPatientList(doctorNumber: doctorNumber, periodId: currentRemittance.periodId) { (patientListArray, error) in
guard let patientListPerPayout = patientListArray, error == nil else {
if let networkError = error {
switch networkError {
case .noRecordFound:
let alertController = UIAlertController(title: "No Record Found", message: "You don't have current payment remittance", preferredStyle: .alert)
alertController.addAction(UIAlertAction(title: "OK", style: .default))
self.present(alertController, animated: true, completion: nil)
case .noNetwork:
let alertController = UIAlertController(title: "No Network", message: "\(networkError.rawValue)", preferredStyle: .alert)
alertController.addAction(UIAlertAction(title: "OK", style: .default))
self.present(alertController, animated: true, completion: nil)
default:
let alertController = UIAlertController(title: "Error", message: "There is something went wrong. Please try again", preferredStyle: .alert)
alertController.addAction(UIAlertAction(title: "OK", style: .default))
self.present(alertController, animated: true, completion: nil)
}
}
SVProgressHUD.dismiss()
return
}
self.patientList = patientListPerPayout
self.latestCreditedAmountTableView.reloadData()
SVProgressHUD.dismiss()
return
}
}
**getPerPatientPAyoutDetails(from: String) function**
func getPerPatientPayoutDetails(from: String) {
SVProgressHUD.setDefaultMaskType(.black)
SVProgressHUD.showInfo(withStatus: "Retrieving Patient Details")
APIService.PatientList.getPatientDetailsPerPayout(periodId: currentRemittance.periodId, doctorNumber: doctorNumber, parameterName: .selectedByHospitalNumber, hospitalNumber: from) { (patientPayout, error) in
guard let patientPerPayoutDetails = patientPayout, error == nil else {
if let networkError = error {
switch networkError {
case .noRecordFound:
let alertController = UIAlertController(title: "No Record Found", message: "You don't have current payment remittance", preferredStyle: .alert)
alertController.addAction(UIAlertAction(title: "OK", style: .default))
case .noNetwork:
let alertController = UIAlertController(title: "No Network", message: "\(networkError.rawValue)", preferredStyle: .alert)
alertController.addAction(UIAlertAction(title: "OK", style: .default))
self.present(alertController, animated: true, completion: nil)
default:
let alertController = UIAlertController(title: "Error", message: "There is something went wrong. Please try again", preferredStyle: .alert)
alertController.addAction(UIAlertAction(title: "OK", style: .default))
self.present(alertController, animated: true, completion: nil)
}
}
SVProgressHUD.dismiss()
return
}
self.selectedPatientPayment = patientPerPayoutDetails
print(self.selectedPatientPayment)
SVProgressHUD.dismiss()
return
}
}
Base on the gePatientList() function, it will just pull the full list of the patients. I don't know how I will pass the data of the selected patient to another VC. Hope you can help me. Thank you so much.
Codes that might help to understand the flow of my codes
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
switch indexPath.section {
case 0: break
case 1: let selectedpatient = patientList[indexPath.row].hospitalNumber
print(selectedpatient!)
self.isBrowseAll = false
getPerPatientPayoutDetails(from: selectedpatient!)
default: break
}
}
Below is the another View Controller that will display the patientName and hospitalNumber
PatientPaymentDetailsVC
class PatientPaymentDetailsViewController: UIViewController {
#IBOutlet weak var patientProcedureTableView: UITableView!
#IBOutlet weak var hospitalNumberLabel: UILabel!
#IBOutlet weak var patientNameLabel: UILabel!
var currentRemittance: CurrentRemittance!
var doctorNumber: String!
var isBrowseAll: Bool!
var patientList: [Patient]!
var patientPayoutDetails: [PatientPayoutDetails]!
override func viewDidLoad() {
super.viewDidLoad()
setupPatientInfo()
}
//MARK: FUNCTION
func setupPatientInfo() {
self.patientNameLabel.text = patient.patientName
self.hospitalNumberLabel.text = patient.hospitalNumber
}
The pulled data under the getPerPatientPayoutDetails function from the didselect will be displayed in PatientPaymentDetailsVC. Below is the output, as you can I see I can pull the data under getPerPatientPayoutDetails but the patientName and hospitalNumber does not display the data.

Answer 1

First of all don't get the data from the table view cell, get it from the data source
Connect the segue to the cell.
Delete the entire method didSelectRowAt
When prepare(for segue is called the sender parameter is the cell.
Get the index path from the cell and get the patient at that index path.
Rather than passing multiple parameters declare a var patient : Patient! property in the destination controller and hand over the patient instance.
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
guard segue.identifier == "showPatientPaymentDetailsVC",
let cell = sender as? UITableViewCell,
let indexPath = tableView.indexPath(for: cell) else { return }
let patient = patientList[indexPath.row]
getPerPatientPayoutDetails(from: patient.hospitalNumber)
let patientPaymentDetailsVC = segue.destination as! PatientPaymentDetailsViewController
patientPaymentDetailsVC.patient = patient
patientPaymentDetailsVC.patientPayoutDetails = self.selectedPatientPayment
patientPaymentDetailsVC.currentRemittance = self.currentRemittance
patientPaymentDetailsVC.doctorNumber = self.doctorNumber
}
class PatientPaymentDetailsViewController: UIViewController {
#IBOutlet weak var patientProcedureTableView: UITableView!
#IBOutlet weak var hospitalNumberLabel: UILabel!
#IBOutlet weak var patientNameLabel: UILabel!
var currentRemittance: CurrentRemittance!
var doctorNumber = ""
var isBrowseAll = false
var patient : Patient!
var patientPayoutDetails: [PatientPayoutDetails]!
override func viewDidLoad() {
super.viewDidLoad()
setupPatientInfo()
}
//MARK: FUNCTION
func setupPatientInfo() {
self.patientNameLabel.text = patient.patientName
self.hospitalNumberLabel.text = patient.hospitalNumber
}
Side note:
Don't declare patientList as implicit unwrapped optional, declare it as non-optional empty array
var patientList : [Patient]()

Answer 2

Use tableView(_:didSelectRowAt:) method by conforming to UITableViewDelegate.
Get the selected patient as displayed below:
selectedPatient = tableView[indexpath.row] as! [String:Any]
As per your edited question, try this:
let patient = patientList[indexPath.row] as! Patient
