UITableView Checkmark not appearing when selected - ios

Question

I am using a UITableView on button click i am putting the tableview into edit mode I have added
tableView.allowMultiselectionduringedit = true
Here i am getting circles to select the table but no check mark is added when tapped. But code in didselectrow is getting executed
I have attached a picture
What should i change to get the rows selected
Code for didselect
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print("Did select Run")
if(isEditing){
let cell = chatTableView.cellForRow(at: indexPath)
cell?.setSelected(true, animated: true)
}else{
let groupMsg = groupMsgList[indexPath.row]
if(groupMsg.messageType == "file")
{
let fileNameString = groupMsg.fileOriginalName
if(fileNameString != nil){
let fileName: NSString = fileNameString! as NSString
let extention = fileName.pathExtension.lowercased()
switch extention {
case "jpg","png","jpeg":
if (groupMsg.senderUserId != LoginStatusInfo.userId){
let row = chatTableView.cellForRow(at: indexPath) as! PhotoReciveCell
chatTableView.beginUpdates()
row.downloadLabel.text = " Downloading... "
row.downloadLabel.sizeToFit()
row.downloadLabelConstraint.constant = 30.0
row.downloadLabel.layoutMargins = UIEdgeInsets(top: 2.0, left: 2.0, bottom: 2.0, right: 2.0)
downloadFileBackground(id: groupMsg.messageId!, fileName: groupMsg.message!, cellIndexPath: indexPath )
chatTableView.endUpdates()
}else{
let row = chatTableView.cellForRow(at: indexPath) as! PhotoSentCell
chatTableView.beginUpdates()
row.downloadLabel.text = " Downloading... "
row.downloadLabel.sizeToFit()
row.downloadLabelConstraint.constant = 30.0
row.downloadLabel.layoutMargins = UIEdgeInsets(top: 2.0, left: 2.0, bottom: 2.0, right: 2.0)
downloadFileBackground(id: groupMsg.messageId!, fileName: groupMsg.message!, cellIndexPath: indexPath )
chatTableView.endUpdates()
}
break
default :
if (groupMsg.senderUserId != LoginStatusInfo.userId){
let row = chatTableView.cellForRow(at: indexPath) as! FileRecieveCell
chatTableView.beginUpdates()
row.downloadStatusIndicator.isHidden = true
row.downloadingIndicator.alpha = 1.0
chatTableView.endUpdates()
}else{
let row = chatTableView.cellForRow(at: indexPath) as! FileSentCell
chatTableView.beginUpdates()
row.downloadStatusIndicator.isHidden = true
row.downloadingIndicator.alpha = 1.0
chatTableView.endUpdates()
}
downloadFileBackground(id: groupMsg.messageId!, fileName: groupMsg.fileOriginalName!, cellIndexPath: indexPath )
break
}
}
}
print(indexPath)
}
}
For CellatRow
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

cell.message.text = groupMsg.message
cell.time.text = groupMsg.dateSent!
// cell.message.sizeToFit()
cell.receiveMessageView.tag = indexPath.row
cell.receiveMessageView.addGestureRecognizer(longPressGesture)
return cell
}
else
{
let cell : SentMessageCell = chatTableView.dequeueReusableCell(withIdentifier: "send") as! SentMessageCell
// cell.sentMessageView.roundCorners(corners: [.topLeft,.topRight,.bottomLeft], radius: 20)

}
}
//MARK: Message type is Banner
else if (groupMsg.messageType == "banner") {

hasBanner = true

let fileUrl = self.getImageURL(forFileName: fileNameString!)
if(fileUrl == nil){
cell.downloadStatusIndicator.image = #imageLiteral(resourceName: "fileDonwloadBlack")

Answer 1

Solved!
My Mistake was i needed to add cell.setSelectionStype = .default in cellForAtRow

Answer 2

Tableview use dequeueReusableCell , so you can
cell?.setSelected(true, animated: true)
When you scroll tableview , the same cell - reusable from a cell will is selected -> wrong.
In GroupMessage model add property: isSelected . and set
isSelected = true
self.tableview.reloadrowatindexpath ....
when didselected
In cellForRowAt indexPath
If groupMsg.isSelected{
cell?.setSelected(true, animated: true)
}else{
cell?.setSelected(false, animated: true)
}
OR create a NSMutableArray - selectedMessage to hold message selected didSelected add/remove groupmessage in selectedMessage
In cellForRowAt indexPath check selectedMessage contains groupmessage - setSelected = true or no
