I want to pass the data from second ViewController to TableView cell through protocol - ios

Question

This is my ViewController2 from where I need to pass the data.
How do I pass the data?
protocol oppo {
func datapass(Name:String,className:String,rollnumner:String, school:String)
}
class ViewController2: UIViewController {
#IBOutlet weak var txtFldNames: UITextField!
#IBOutlet weak var txtFldClasss: UITextField!
#IBOutlet weak var txtFldRoll: UITextField!
#IBOutlet weak var txtFldSchool: UITextField!
var datatrsfer:oppo!
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func actionAdd(_ sender: UIButton) {
datatrsfer.datapass(Name: txtFldNames.text!, className: txtFldClasss.text!, rollnumner: txtFldRoll.text!, school: txtFldSchool.text!)
}
}
// this is main viewcontoller
class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {
var dataArry = NSMutableArray()
#IBOutlet weak var tblView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
#IBAction func actionPush(_ sender: UIButton) {
let vc = storyboard?.instantiateViewController(identifier: "ViewController2") as! ViewController2
vc.datatrsfer = self
self.navigationController?.pushViewController(vc, animated: true)
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
dataArry.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "TableViewCell", for: indexPath) as! TableViewCell
return cell
}
}
class TableViewCell: UITableViewCell,oppo {
#IBOutlet weak var txtFldName: UITextField!
#IBOutlet weak var txtFldClass: UITextField!
#IBOutlet weak var txtFldRoll: UITextField!
#IBOutlet weak var txtFldScholl: UITextField!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
func datapass(Name: String, className: String, rollnumner: String, school: String) {
txtFldName.text = Name
txtFldClass.text = className
txtFldRoll.text = rollnumner
txtFldScholl.text = school
}
}

import UIKit
class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource,oppo {
let nam = NSMutableArray()
#IBOutlet weak var tblView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
#IBAction func actionPush(_ sender: UIButton) {
let vc = storyboard?.instantiateViewController(identifier: "ViewController2") as! ViewController2
vc.datatrsfer = self
self.navigationController?.pushViewController(vc, animated: true)
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return nam.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "TableViewCell", for: indexPath) as! TableViewCell
if let dict = nam[indexPath.row] as? NSMutableDictionary {
cell.txtFldName.text = dict["name"] as? String
cell.txtFldClass.text = dict["classname"] as? String
cell.txtFldRoll.text = dict["rollnumber"] as? String
cell.txtFldScholl.text = dict["school"] as? String
}
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 300
}
func datapass(Name: String, className: String, rollnumner: String, school: String) {
let dict = NSMutableDictionary()
dict.setValue(Name, forKey: "name")
dict.setValue(className, forKey: "classname")
dict.setValue(rollnumner, forKey: "rollnumber")
dict.setValue(school, forKey: "school")
nam.add(dict)
tblView.reloadData()
}
}
