func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return array.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "TableViewCell", for: indexPath) as!TableViewCell
cell.lblName.text = array[indexPath.row]
cell.lblFullName.text = array[indexPath.row]
cell.lblRollno.text = array[indexPath.row]
cell.lblClass.text = array[indexPath.row]
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 200
}
#IBAction func btnPush(_ sender: UIButton) {
let vc = storyboard?.instantiateViewController(withIdentifier: "SecondVC") as!SecondVC
vc.mac = self
self.navigationController?.pushViewController(vc, animated: true)
}
func Datapass(Name: String, FullName Address: String, Rollno: String, Class: String) {
self.array.append(Name)
self.array.append(Address)
self.array.append(Rollno)
self.array.append(Class)
tblView.reloadData()
}
}
import UIKit
protocol pass {
func Datapass(Name:String, FullName:String, Rollno:String, Class:String)
}
class SecondVC: UIViewController {
#IBOutlet weak var textFldName: UITextField!
#IBOutlet weak var txtFldFullName: UITextField!
#IBOutlet weak var txtFldRollno: UITextField!
#IBOutlet weak var txtFldClass: UITextField!
var mac:pass?
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func btnAdd(sender: UIButton) {
mac?.Datapass(Name: textFldName.text!, FullName: txtFldFullName.text!, Rollno: txtFldRollno.text!, Class: txtFldClass.text!)
self.navigationController?.popViewController(animated: true)
}
}

Answer 1

your adding data to your array the wrong way. your adding 4 parameter
and your array will be like this:
array: 0:name|1:Address|2:Rollno|3:Class
and when your reading this from table every time you map this:
cell.lblName.text = array[0]
cell.lblFullName.text = array[0]
cell.lblRollno.text = array[0]
cell.lblClass.text = array[0]
every time table only reads one element of array for 4 times! you are not changing indexpath.row , it will change it's number after loading 1 cell.
the right way to do this is code below:
struct DbModel{
var name:String
var address:String
var rollno:String
var `class`:String
}
var array :[DbModel] = []
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "TableViewCell", for: indexPath) as! TableViewCell
let model = array[indexPath.row]
cell.lblName.text = model.name
cell.lblFullName.text = model.address
cell.lblRollno.text = model.rollno
cell.lblClass.text = model.class
return cell
}
func Datapass(Name: String, FullName Address: String, Rollno: String, Class: String) {
let model = DbModel(name: Name, address: Address, rollno: Rollno, class: Class)
self.array.append(model)
tblView.reloadData()
}
