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

Question

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?

Answer 1

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"
}

Answer 2

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,
