每当我选择第 4 个单元格时,我在 uitableview 中遇到问题,没有自动选择单元格...我厌倦了这个问题,有人请帮助这里是我的 didselectrowfunc..
////////////////For Adding Check Box////////////////////////
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if tableView.cellForRow(at: indexPath)?.accessoryType == UITableViewCellAccessoryType.checkmark
{
if selectedDisease.count > 0
{
let no = selectedDisease.index(of: finall[indexPath.row])
selectedDisease.remove(at: no!)
tableView.cellForRow(at: indexPath)?.accessoryType = UITableViewCellAccessoryType.none
print(selectedDisease)
}
else
{
selectedDisease = [""]
}
}
else
{
if selectedDisease.contains("")
{
selectedDisease.removeAll()
var name = finall[indexPath.row]
selectedDisease.append(name)
tableView.cellForRow(at: indexPath)?.accessoryType = UITableViewCellAccessoryType.checkmark
print(selectedDisease)
}
else
{
tableView.cellForRow(at: indexPath)?.accessoryType = UITableViewCellAccessoryType.checkmark
selectedDisease.append(finall[indexPath.row])
//selectedDisease = [finall[indexPath.row]]
print(selectedDisease)
}
}
}
/////////CellForRowAt///////////////
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "diseasetable", for: indexPath) as! FoodTableViewCell
cell.DiseaseName.text = finall[indexPath.row]
//indexsave.append(indexPath.row)
return cell
}
最佳答案
试试这个逻辑希望这能解决你的问题
let dict = [NSIndexPath: String]()
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)
if let _ = // dict contains value at indexpath {
cell.accessoryType = .Checkmark
} else {
cell.accessoryType = .None
}
return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if ( // dict contains value == indexpath) {
// remove value from dict
} else {
//add value to dict
}
tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: .Automatic)
}
