CGPoint touchPoint = [sender convertPoint:CGPointZero toView:_tableView];
  NSIndexPath *indexPath = [_tableView indexPathForRowAtPoint:touchPoint];
    sender.tag = indexPath.row;
    selectedIndexForPassing = sender.tag;
    if([_selectionArray count ] == 0){
  _uploadSheetBtn.enabled = NO;
if (sender.selected){
    sender.selected = false;

}
else{
    TCSTimeSheet * sc = self.timesheetList[selectedIndexForPassing];
    _canEdit = sc.canEdit;
    if([_canEdit  isEqual: @"1"]){
    sender.selected = true;
    _uploadSheetBtn.enabled = YES;


    TCSTimeSheet * sc = self.timesheetList[selectedIndexForPassing];

    NSDictionary * detailsDictionary= [NSDictionary dictionaryWithObjectsAndKeys:sc.timesheetDetailId,@"timesheetDetailId",sc.scheduleEmployeeDetailId, @"scheduleDetailId",sc.lastUpdatedTime,@"lastUpdatedTime",sc.timesheetStatus,@"timesheetStatus",sc.shiftDate , @"shiftDate",sc.employeeId ,@"employeeId",nil];

    [_storingArray addObject:detailsDictionary];

    [_selectionArray addObject:sc.clientId];
    }

}

}

here is my cell for at indexpath code

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

   static NSString *  reuseIdentifier = @"timeSheetCell" ;


        TimeSheetCell * dataCell =  [tableView dequeueReusableCellWithIdentifier:reuseIdentifier];

        if (dataCell == nil)
           {
               dataCell = [[TimeSheetCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:reuseIdentifier];

           }

            dataCell.clientNameLbl.text = currentTimeSheet.clientName;
            dataCell.dayLbl.text = currentTimeSheet.shiftDay;
            dataCell.dateLbl.text = currentTimeSheet.shiftDate;
            dataCell.shiftTime.text = currentTimeSheet.shiftTime;
            dataCell.shiftType.text = currentTimeSheet.shiftType;


        [dataCell.checkBtn addTarget:self action:@selector(checkButtonClicked:) forControlEvents:UIControlEventTouchUpInside];

       if ([_statusIndicator  isEqual: @"D"]) {

           if([currentTimeSheet.canEdit isEqual:@"1"]) {

            }



    }



        return dataCell ;

    }



**button action of the tick mark**

Answer 1

The cell will reuse, but the model will not, and the state of the view should be recorded in the model
