How to change text of Label in UITableView based on button pressed?

I have a UITableView in ViewController which displays Default, five times on running in the simulator based on the following code.

class ViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {

    @IBOutlet weak var myTableView: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    func tableView(_ tableView:UITableView, numberOfRowsInSection section:Int) -> Int
    {
        return 5
    }

   func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
         let myCell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! OutsideCell
          myCell.titleLabel.text = "Default"
    return myCell
    }

    @IBAction func firstButtonPressed(_ sender: Any){


    }

    @IBAction func secondButtonPressed(_ sender: Any) {

    }

}

I also have 2 buttons at the bottom of ViewController and I like to display text as First Button when firstButtonPressed and Second Button when secondButtonPressed instead of Default in UITableView. How is this possible?

You should use a generic method as eventButtonPressed and use the tag attribute to determine which button is pressed through the storyboard.

@IBAction func eventButtonPressed(_ sender: UIButton) {
    if (sender.tag == 0) {
       //First Button
    } else if (sender.tag == 1) {
       //Second Button
    }
}

You can use switch operand if you have many cases.

switch sender.tag {
   case 0:
      print("First button pressed")
   case 1:
      print("Second button pressed")
   default:
     print("Default button pressed")
}

Hope it helps,

You can loop through each cell of the table view when the button is tapped.

for cell in myTableView.visibleCells() {
   cell.titleLabel?.text = "First Button"
}
