I am trying to reload my TableView but I am getting this exception "Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'attempt to delete row 3 from section 1 which only contains 0 rows before the update'".
Below is my code :-
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
if statusTableView == tableView
return ModelAssessStatus.sharedInstance.arrType.count
else
if !sections[section].expanded
return 0
else
return sections[section].names.count
//return sections[section].names.count
/*if sections[section].expanded == true
return sections[section].names.count
else
return 0
*/
.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
var expandableCategoryCell = tableView.dequeueReusableCell(withIdentifier: "ExpandableCategoryCell") as? ExpandableCategoryCell
if expandableCategoryCell == nil
var nib:Array = Bundle.main.loadNibNamed("ExpandableCategoryCell", owner: self, options: nil)!
expandableCategoryCell = nib[0] as? ExpandableCategoryCell
expandableCategoryCell?.selectionStyle = .none
expandableCategoryCell?.labelName.text = sections[indexPath.section].names[indexPath.row]
return expandableCategoryCell!
//return UITableViewCell()
.
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat
if tableView == self.expandableTableView
return 60
return 0
func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat
if tableView == self.expandableTableView
return 0
return 0
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
if tableView == expandableTableView
let cell = self.expandableTableView.dequeueReusableHeaderFooterView(withIdentifier: "ExpandableHeaderView")
let header = cell as! ExpandableHeaderView
header.customInit(title: sections[section].categoryType, section: section, delegate: self, isSelected: sections[section].fullSelected)
if sections[section].expanded
header.imgArrow?.image = UIImage(named : "down_Arow")//.transform = (header.imgArrow?.transform.rotated(by: CGFloat(Double.pi)))!
else
header.imgArrow?.image = UIImage(named : "error")
return cell
else
return UIView.init(frame: CGRect(x: 0, y: 0, width: 0, height: 0))
//Height For Raw at indexPath
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat
if statusTableView == tableView
return 50
else
if (sections[indexPath.section].expanded)
return 60
else
return 0
}
extension PeerCategoryStatusVC : expandableHeaderViewDelegate
func toggleSections(header: ExpandableHeaderView, section: Int)
sections[section].expanded = !sections[section].expanded
//expandableTableView.reloadData()
expandableTableView.beginUpdates()
for index in 0..<sections[section].names.count
expandableTableView.reloadRows(at: [IndexPath(row : index, section : section)], with: .automatic)
expandableTableView.endUpdates()
//self.view.layoutIfNeeded()
.
Here Begin Update and End Update TableView.
I am trying to reload tableView but don't know why I am getting exception.
If I will keep same number of rows then constraints issue is coming.
Is there anything which I have to add ?
