Answer 1

Keep the star count in your listDayDetailsData and update the value according to the button taps
LeaveDayDetailsCell
class LeaveDayDetailsCell: UITableViewCell {
#IBOutlet weak var leaveDateLabel: UILabel!
#IBOutlet weak var leaveDateName: UILabel!
#IBOutlet weak var firstButton: UIButton!
#IBOutlet weak var seconButton: UIButton!
#IBOutlet weak var fullButton: UIButton!
}
DayDetailsController extension
extension DayDetailsController:UITableViewDelegate,UITableViewDataSource{
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return listDayDetailsData.count
}
#objc func firstButtonPressed(sender: UIButton) {
let index = sender.tag
// Update star value in listDayDetailsData[index]
// Reload single row at index 0
dayDetailsTableView.reloadRows(at: [IndexPath(row: index, section: 0)], with: .none)
}
#objc func secondButtonPressed(sender: UIButton) {
let index = sender.tag
// Update star value in listDayDetailsData[index]
// Reload single row at index 0
dayDetailsTableView.reloadRows(at: [IndexPath(row: index, section: 0)], with: .none)
}
#objc func fullButtonPressed(sender: UIButton) {
let index = sender.tag
// Update star value in listDayDetailsData[index]
// Reload single row at index 0
dayDetailsTableView.reloadRows(at: [IndexPath(row: index, section: 0)], with: .none)
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier:"LeaveDayDetailsCell",for: indexPath) as! LeaveDayDetailsCell
// cell.leaveDateLabel.text = listDayDetailsData[indexPath.row]["BreakDate"] as? String ?? "-"
// cell.leaveDateName.text = listDayDetailsData[indexPath.row]["DateName"] as? String ?? "-"
cell.layer.borderColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
cell.layer.borderWidth = 2
cell.firstButton.tag = indexPath.row
cell.seconButton.tag = indexPath.row
cell.fullButton.tag = indexPath.row
cell.firstButton.addTarget(self, action: #selector(firstButtonPressed(sender:)), for: .touchUpInside)
cell.firstButton.addTarget(self, action: #selector(secondButtonPressed(sender:)), for: .touchUpInside)
cell.firstButton.addTarget(self, action: #selector(fullButtonPressed(sender:)), for: .touchUpInside)
switch listDayDetailsData[indexPath.row]["Star"] as! Int {
case 1:
// Update your cell buttons
break
case 2:
// Update your cell buttons
break
case 3:
// Update your cell buttons
break
default:
// Default case
break
}
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 132.00
}
}
Pro tip:
It's better to use an Object for keeping your data than a Dictionary
eg
struct DayDetails {
var breakDate: String
var dateName: String
var stars: Int
//....
}
And there are third party libraries available for handling star rating UI as well
