tableview custom cell button single selection/deselction - swift

Question

i have been coding for a while i am stuck with tableview single selection/deselection.
I have a tableview with custom cell which has a button. if i click on one button another button in bottom gets selected as well.For example when i click on button with index 2 another button gets click in the button.
it should be like when i click on one button other buttons should be deselected.
Thanks!
func QuickReview( sender: UIButton){
if cell.EventReviewQuickeReviewBtn.isSelected == true {
cell.EventReviewQuickeReviewBtn.layer.borderColor = UIColor.red
cell.EventReviewQuickeReviewBtn.backgroundColor = UIColor.white
cell.EventReviewQuickeReviewBtn.layer.borderWidth = 1
cell.EventReviewQuickeReviewBtn.isSelected = false
}
else {
cell.EventReviewQuickeReviewBtn.layer.backgroundColor = UIColor.green
cell.EventReviewQuickeReviewBtn.setTitleColor(UIColor.white, for: .normal)
cell.EventReviewQuickeReviewBtn.isSelected = true
}
}

Answer 1

Cells get reused. You need to ensure the exact same set of properties are set/reset in both conditions.
func QuickReview( sender: UIButton){
if cell.EventReviewQuickeReviewBtn.isSelected {
cell.EventReviewQuickeReviewBtn.layer.borderColor = UIColor.red
cell.EventReviewQuickeReviewBtn.backgroundColor = UIColor.white
cell.EventReviewQuickeReviewBtn.layer.backgroundColor = UIColor.white // or whatever
cell.EventReviewQuickeReviewBtn.layer.borderWidth = 1
cell.EventReviewQuickeReviewBtn.setTitleColor(UIColor.red, for: .normal) // or whatever
} else {
cell.EventReviewQuickeReviewBtn.layer.borderColor = UIColor.black // or whatever
cell.EventReviewQuickeReviewBtn.backgroundColor = UIColor.green // or whatever
cell.EventReviewQuickeReviewBtn.layer.backgroundColor = UIColor.green
cell.EventReviewQuickeReviewBtn.layer.borderWidth = 3 // or whatever
cell.EventReviewQuickeReviewBtn.setTitleColor(UIColor.white, for: .normal)
}
cell.EventReviewQuickeReviewBtn.isSelected = !cell.EventReviewQuickeReviewBtn.isSelected
}

Answer 2

when you select any button then you should have mark isSelected property to false
assuming you have a list of models for your table view like
class Example{
...
var isSelected: Bool
...
}
(in ViewController)
let list: [Example] = [example1, example2, example3]
on tap of any button deselect all then selected desire button like
list.forEach { (example) in
example.isSelected = false
}
list[selectedButtonIndex].isSelected = true
and then reload your tableView.
