我当前正在设置一个分组表视图,当视图加载时,根据从用户默认值中提取的结果,在一个区域中的tableview单元格上设置复选框。当用户点击该部分中的另一个单元格时,另一个单元格上的复选框将消失,并且他们刚刚点击的单元格上会显示一个新的复选框。
这似乎在最初点击不同的单元格时有效,但在3次更改后,您必须点击单元格两次才能更改复选框。看起来每个其他的tap tableView(_ tableView:UITableView,didSelectRowAt indexPath:IndexPath)都没有被调用。
感谢您提前提供任何帮助,代码如下:
var selectedIndex: IndexPath? = nil
let usersettings = UserDefaults.standard
override func viewDidLoad() {
super.viewDidLoad()
settingsTableView.delegate = self
settingsTableView.dataSource = self
//Load current preferences from user defaults
spamNumbersSetting = usersettings.value(forKey: "spamNumbersSetting") as! Int
personalNumbersSetting = usersettings.value(forKey: "personalNumbersSetting") as! Int
settingsSaveButton.isEnabled = false
// Do any additional setup after loading the view.
}
func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int){
let header = view as! UITableViewHeaderFooterView
header.textLabel?.textColor = UIColor.white
}
func numberOfSections(in tableView: UITableView) -> Int {
return settingsHeaders.count
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return settingsHeaders[section]
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return settingsContent[section].count
}
func tableView(_ tableView:UITableView, cellForRowAt indexPath:IndexPath) -> UITableViewCell {
let cell:UITableViewCell = tableView.dequeueReusableCell(withIdentifier: "myCell", for: indexPath)
//Preset ticks depending on value of user settings
if indexPath.section == 0 {
if (spamNumbersSetting == 1) {
if indexPath.row == 0 {
cell.accessoryType = UITableViewCellAccessoryType.checkmark
selectedIndex = indexPath
}
} else {
if indexPath.row == 1 {
cell.accessoryType = UITableViewCellAccessoryType.checkmark
selectedIndex = indexPath
}
}
}
if indexPath.section == 1 {
if (personalNumbersSetting == 1){
cell.accessoryType = UITableViewCellAccessoryType.checkmark
}
}
cell.textLabel?.textColor = UIColor.white
let section = indexPath.section
cell.textLabel?.text = settingsContent[section][indexPath.row]
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
self.tableView(tableView, didDeselectRowAt: selectedIndex!)
settingsSaveButton.isEnabled = true
let newCell = tableView.cellForRow(at: indexPath)
print("\(newCell?.textLabel?.text) is now the active cell !")
let oldCell = tableView.cellForRow(at: selectedIndex!)
//Deselect old cell
if indexPath.section == 0 {
if newCell?.accessoryType != .checkmark {
newCell?.accessoryType = .checkmark
//oldCell?.accessoryType = .none
} else {
newCell?.accessoryType = .none
}
selectedIndex = indexPath
}
}
func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
let cell = tableView.cellForRow(at: indexPath)
print("Deselected \(cell?.textLabel?.text) !")
cell?.accessoryType = .none
}
答案 0 :(得分:1)
取消选择动作执行到didSelectRowAt
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
tableView .deselectRow(at: indexPath, animated: false)
}
