How Create Global Array and save Values in Two TableViews in Swift - arrays

Question

Here i am creating Global array and appending values to it, which i need to save in two different viewcontrollers tableview
Global array and appending values and sending to two view controllers code:
var addressArray = [String]()
class NewZoomAddressViewController: UIViewController {
weak var delegate: DataEnteredDelegate? = nil
//var addressArray = [String]()
var zipName: String?
var localityName: String?
var sublocalityName: String?
var streetNumber: String?
var streetName: String?
#IBOutlet weak var mapView: MKMapView!
#IBOutlet weak var addressLabel: UILabel!
var viewController: UIViewController?
#IBAction func confirmBtn(_ sender: Any) {
for controller in navigationController?.viewControllers ?? [] {
if let listController = controller as? ProfileViewController {
let string = "\(streetNumber ?? "") \(streetName ?? "") \(sublocalityName ?? "") \(zipName ?? "") \(localityName ?? "")"
saveaddAddressService()
listController.addressArray.append(string)
navigationController?.popToViewController(controller, animated: true)
return
}
else if let listController = controller as? Add_EditAddressViewController {
let string = "\(sublocalityName ?? "") \(zipName ?? "") \(localityName ?? "")"
listController.addressArray.append(string)
saveaddAddressService()
navigationController?.popToViewController(controller, animated: true)
return
}
}
}
func saveaddAddressService(){
let parameters: [String: Any] = [
"pincode": zipName,
"city": localityName,
"streetName": sublocalityName,
"colony": "",
]
//some JSON code.....
let httpResponse = response as? HTTPURLResponse
if httpResponse!.statusCode == 200 {
do {
let jsonObject = try JSONSerialization.jsonObject(with: data!, options: .mutableLeaves) as! [String: Any]
self.addAddrsID = jsonObject["addressId"] as! String
UserDefaults.standard.set(self.addAddrsID, forKey: "addAddress")
} catch { print(error.localizedDescription) }
}
})
dataTask.resume()
}
Saving array in first view controller view controllers: here i am getting each time with new address the model address also coming, i dont know why?
class ProfileViewController: UIViewController {
var userModel : ProfileModel?
var addressArray = [String]()
override func viewWillAppear(_ animated: Bool) {
self.navigationController?.navigationBar.isHidden=true
getUserProfile()
}
func getUserProfile() {
let httpResponse = response as? HTTPURLResponse
if httpResponse!.statusCode == 200 {
do {
let jsonObject = try JSONSerialization.jsonObject(with: data!, options: .mutableLeaves) as! [String :AnyObject]
self.userModel = ProfileModel.init(fromDictionary: jsonObject)
if (self.userModel?.userId) != nil {
DispatchQueue.main.async {
self.updateUserDetails()
self.addressTableview.reloadData()
}
}
}
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if userModel?.userAddresses != nil{
return userModel?.userAddresses.count ?? 0
}
else{
return addressArray.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell: AddresCell = tableView.dequeueReusableCell(withIdentifier: "AddresCell") as! AddresCell
let addr = userModel?.userAddresses![indexPath.row]
if addr?.addressId != nil{
let street = addr?.streetName
let colony = addr?.colony
let city = addr?.city
let pincode = addr?.pincode
cell.address.text = street! + "," + colony! + "," + city! + "," + pincode!
}
else{
cell.address.text = addressArray[indexPath.row]
print("added address in profilr \(cell.address.text)")
}
return cell
}
saving global array in second view controller: here array values are coming, but if i go from this view controller to other view controller the array values gone(not coming.. showing empty.. not saving)
class Add_EditAddressViewController: UIViewController,DataEnteredDelegate {
#IBOutlet weak var addeditTableview: UITableView!
var addressArray = [String]()
override func viewWillAppear(_ animated: Bool) {
addeditTableview.reloadData()
}
}
extension Add_EditAddressViewController : UITableViewDelegate,UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return addressArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "EditAddressTableViewCell", for: indexPath) as! EditAddressTableViewCell
cell.editButton.addTarget(self, action: #selector(editbuttonClicked(sender:)), for: .touchUpInside)
cell.nameHeader.text = "Other"
cell.addressLabel.text = addressArray[indexPath.row]//"\(city) \(pincode) \(locality)"
}
return cell
}

you can create a singleton class to manage your global array like below GlobalArrayManager class:
import Foundation
class GlobalArrayManager{
static let shared = GlobalArrayManager()
var globalArray : [Int] = []
private init(){}
func getArray()->[Int]{
return globalArray
}
func addDataInArray(data : Int){
globalArray.append(data)
}
}
In first ViewController add data and print:
GlobalArrayManager.shared.addDataInArray(data: 100)
print("array values : ",GlobalArrayManager.shared.getArray())
Output In first ViewController:
array values : [100]
In second ViewController add data and print:
GlobalArrayManager.shared.addDataInArray(data: 200)
print("array values : ",GlobalArrayManager.shared.getArray())
Output In Second ViewController:
array values : [100, 200]
you can add more functionalities in your manager class
