ios swift 3 delete contents of each cell when reloading tableView - ios

Question

I am creating a quizApp using DLRadioButton with a label in each cell of tableView, the label is set from the storyBoard(with a tag) but I have set radioButtons programmatically for better design when I click next button to pass to next question new Radiobutton overlaps with the old Radiobutton
here is the first question
here is the second image
Below is my code
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell : UITableViewCell = tableView.dequeueReusableCell(withIdentifier: "cell")!
var reponse = rep[(indexPath as NSIndexPath).row]
let content:UILabel=cell.viewWithTag(111) as! UILabel
//var ra:UIButton=cell.viewWithTag(112) as! UIButton
content.text=reponse["rep"] as? String
content.sizeToFit()
let repiii = reponse["rep"] as? String
// var radio = DLRadioButton()
if (self.type=="case à cocher"){
// cell.contentView.delete(radioButtons)
let frame = CGRect(x: 50, y: 20, width: 200, height: 40)
let squareButton = self.createRadioButton(frame: frame, title:repiii!, color: UIColor.red,compt: squareButtons.count,sqaure:1);
squareButtons.append(squareButton)
cell.contentView.addSubview(squareButton)
}
else{
let frame = CGRect(x: 50, y: 20, width: 200, height: 40)
let radioButton = self.createRadioButton(frame: frame, title:repiii!, color: UIColor.blue,compt: radioButtons.count,sqaure:0);
//radioButton.isMultipleSelectionEnabled = true
print(radioButtons.count)
radioButtons.append(radioButton)
cell.contentView.addSubview(radioButton)
}
return cell
}
any suggestion is appreciated

Answer 1

in your code, just after the line
let cell : UITableViewCell = tableView.dequeueReusableCell(withIdentifier: "cell")!
add this:
for subview in cell.contentView.subviews {
subview.removeFromSuperView()
}
