Один из способов решения вашей проблемы заключается в следующем
1. First create a protocol to know when button is clicked
protocol MyCellDelegate: class {
func cellButtonClicked(_ indexPath: IndexPath)
}
2. Now in your cell class, you could do something like following
class MyCell: UITableViewCell {
var indexPath: IndexPath?
weak var cellButtonDelegate: MyCellDelegate?
func configureCell(with value: String, atIndexPath indexPath: IndexPath, selected: [IndexPath]) {
self.indexPath = indexPath //set the indexPath
self.textLabel?.text = value
if selected.contains(indexPath) {
//this one is selected so do the stuff
//here we will chnage only the background color
backgroundColor = .red
self.textLabel?.textColor = .white
} else {
//unselected
backgroundColor = .white
self.textLabel?.textColor = .red
}
}
@IBAction func buttonClicked(_ sender: UIButton) {
guard let delegate = cellButtonDelegate, let indexPath = indexPath else { return }
delegate.cellButtonClicked(indexPath)
}
}
3. Now in your controller. I'm using UItableViewController here
class TheTableViewController: UITableViewController, MyCellDelegate {
let cellData = ["cell1","cell2","cell3","cell4","cell2","cell3","cell4","cell2","cell3","cell4","cell2","cell3","cell4","cell2","cell3","cell4","cell2","cell3","cell4"]
var selectedIndexpaths = [IndexPath]()
override func viewDidLoad() {
super.viewDidLoad()
tableView.register(MyCell.self, forCellReuseIdentifier: "MyCell")
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return cellData.count
}
override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 55.0
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "MyCell", for: indexPath) as! MyCell
cell.cellButtonDelegate = self
cell.configureCell(with: cellData[indexPath.row], atIndexPath: indexPath, selected: selectedIndexpaths)
return cell
}
override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 30.0
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let cell = tableView.cellForRow(at: indexPath) as! MyCell
cell.buttonClicked(UIButton())
}
func cellButtonClicked(_ indexPath: IndexPath) {
if selectedIndexpaths.contains(indexPath) {
//this means cell has already selected state
//now we will toggle the state here from selected to unselected by removing indexPath
if let index = selectedIndexpaths.index(of: indexPath) {
selectedIndexpaths.remove(at: index)
}
} else {
//this is new selection so add it
selectedIndexpaths.append(indexPath)
}
tableView.reloadData()
}
}
