I am trying to save longitude and latitude to Firestore from GoogleAutocomlete but it saves as 0. I am able to save name and address successfully from the textfileds but not longitude and latitude. I am new developer and I am having trouble passing the data.
This the class where I initialized address, longitude and latitude.
class VendorLocation: NSObject, Codable {
var address: String
var latitude: Double
var longitude: Double
init(address: String, latitude: Double, longitude: Double){
self.address = address
self.latitude = latitude
self.longitude = longitude
}
convenience override init() {
self.init(address: "", latitude: 0.0, longitude: 0.0)
}
}
This is the ViewController setting up the table view for each location chosen. Once tapped on the cell with the chosen location, it goes to the next view controller.
class LocationListViewController: UIViewController {
@IBOutlet weak var tableView: UITableView!
@IBOutlet weak var editBarButton: UIToolbar!
@IBOutlet weak var addBarButton: UIBarButtonItem!
var vendorLocations: [VendorLocation] = []
var selectedLocationIndex = 0
var vendorLocation: VendorLocation!
override func viewDidLoad() {
super.viewDidLoad()
tableView.dataSource = self
tableView.delegate = self
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "ShowDetail"{
let destination = segue.destination as! SpotDetailViewController
let selectedIndexPath = tableView.indexPathForSelectedRow!
destination.vendorLocation = vendorLocations[selectedIndexPath.row]
selectedLocationIndex = tableView.indexPathForSelectedRow!.row
// vendorLocations[tableView.indexPathForSelectedRow!.row]
}
}
@IBAction func addButtonPressed(_ sender: UIBarButtonItem) {
let autocompleteController = GMSAutocompleteViewController()
autocompleteController.delegate = self
// Display the autocomplete view controller.
present(autocompleteController, animated: true, completion: nil)
}
@IBAction func editBarButtonPressed(_ sender: UIBarButtonItem) {
if tableView.isEditing{
tableView.setEditing(false, animated: true)
sender.title = "Edit"
addBarButton.isEnabled = true
} else {
tableView.setEditing(true, animated: true)
sender.title = "Done"
addBarButton.isEnabled = true
}
}
}
extension LocationListViewController: UITableViewDataSource, UITableViewDelegate{
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return vendorLocations.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
cell.textLabel?.text = vendorLocations[indexPath.row].address
cell.detailTextLabel?.text = "Lat: \(vendorLocations[indexPath.row].latitude), Long::\(vendorLocations[indexPath.row].longitude)"
return cell
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath){
if editingStyle == .delete {
vendorLocations.remove(at: indexPath.row)
tableView.deleteRows(at: [indexPath], with: .fade)
}
}
func tableView(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath){
let itemToMove = vendorLocations[sourceIndexPath.row]
vendorLocations.remove(at: sourceIndexPath.row)
vendorLocations.insert(itemToMove, at: destinationIndexPath.row)
}
}
extension LocationListViewController: GMSAutocompleteViewControllerDelegate {
// Handle the user's selection.
func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
print("Place name: \(place.name)")
print("Place ID: \(place.placeID)")
print("Place attributions: \(place.attributions)")
let newLocation = VendorLocation(address: place.formattedAddress ?? "unknown place", latitude: place.coordinate.latitude, longitude: place.coordinate.longitude)
vendorLocations.append(newLocation)
tableView.reloadData()
dismiss(animated: true, completion: nil)
}
func viewController(_ viewController: GMSAutocompleteViewController, didFailAutocompleteWithError error: Error) {
// TODO: handle the error.
print("Error: ", error.localizedDescription)
}
// User canceled the operation.
func wasCancelled(_ viewController: GMSAutocompleteViewController) {
dismiss(animated: true, completion: nil)
}
// Turn the network activity indicator on and off again.
func didRequestAutocompletePredictions(_ viewController: GMSAutocompleteViewController) {
UIApplication.shared.isNetworkActivityIndicatorVisible = true
}
func didUpdateAutocompletePredictions(_ viewController: GMSAutocompleteViewController) {
UIApplication.shared.isNetworkActivityIndicatorVisible = false
}
}
```swift
This is the ViewController from where the name and address are saved to Firestore successfully but longitude and latitude are saved as zero.
```swift
class SpotDetailViewController: UIViewController {
@IBOutlet weak var nameTextField: UITextField!
@IBOutlet weak var addressTextField: UITextField!
let db = Firestore.firestore()
let auth = Auth.auth()
var vendorLocation: VendorLocation!
var vendorLocations: [VendorLocation] = []
var vendorAddress: String!
//retrurn zero
var lat = VendorLocation().latitude.self
var long = VendorLocation().longitude.self
override func viewDidLoad() {
super.viewDidLoad()
if vendorLocation == nil{
vendorLocation = VendorLocation()
}
updateUserInterface()
}
func updateUserInterface () {
addressTextField.text = vendorLocation.address
}
func updateFomInterface() {
vendorLocation.address = addressTextField.text ?? "No address"
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let destination = segue.destination as! LocationListViewController
destination.vendorLocations = vendorLocations
}
@IBAction func unwindFromLocationListViewController(segue: UIStoryboardSegue) {
let source = segue.source as! LocationListViewController
vendorLocations = source.vendorLocations
vendorLocation = vendorLocations[source.selectedLocationIndex]
updateUserInterface()
}
@IBAction func saveLocationButtonPressed(_ sender: UIButton) {
updateFomInterface()
if let currentuser = (auth.currentUser?.uid), let vendorName = nameTextField.text, let vendorAddress = addressTextField.text {
db.collection("Vendor").document(currentuser).collection("Locations").addDocument(data: ["name": vendorName, "address": vendorAddress, "latiude": lat, "longtitude": long]) { (error) in
if let e = error {
print("For some reason the data can not be saved to the cloud! \(e)")
} else {
print ("The data was saved successfully!")
}
}
}
}
}
This code makes no sense:
The construct
VendorLocation()invokes the initializer ofVendorLocationto create a new VendorLocation, which will not have a valid address, latitude, or longitude.
