当我选择一行时,它将返回更大或更小的行索引值,但永远不会返回正确的值。如图所示,我选择了14返回16。
这是我使用的代码:
@IBOutlet var cheatTable: UITableView!
let cheetSheet = ["one", "two", "three", "four", "five"]
override func viewDidLoad() {
super.viewDidLoad()
cheatTable.delegate = self
cheatTable.dataSource = self
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 30
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "reuseID")!
let text:String = "\(indexPath.row)"
cell.textLabel?.text = text
return cell
}
func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
guard let currentCell = tableView.cellForRow(at: indexPath) else {
return
}
let alertController = UIAlertController(title: "Hint", message: "You have selected row \(indexPath.row).", preferredStyle: .alert)
let alertAction = UIAlertAction(title: "Ok", style: .cancel, handler: nil)
alertController.addAction(alertAction)
present(alertController, animated: true, completion: nil)
}
我该怎么做才能获得正确的行索引? 谢谢!

检查您的代表姓名不是 didDeselectRowAt
,它是 didSelectRowAt
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
tableView.deselectRow(at: indexPath, animated: true)
let alertController = UIAlertController(title: "Hint", message: "You have selected row \(indexPath.row).", preferredStyle: .alert)
let alertAction = UIAlertAction(title: "Ok", style: .cancel, handler: nil)
alertController.addAction(alertAction)
present(alertController, animated: true, completion: nil)
}
