how to add a value on uilabel with existing value and display it?

I am getting a value from uipickerview and set it on uilabel of uitableviewcell, now i want that if i again get value from picker view than add it to previous value.

Here is my code for cell index:

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
 {
    static NSString *identifier = @"Cell";

    UitableviewcellTableViewCell *Cell = [tableView dequeueReusableCellWithIdentifier:identifier forIndexPath:indexPath];

    if(position == indexPath.row){

    NSString *old  = Cell.nameLabel.text = value;

    int val = [old intValue];

    NSLog(@"val %d", val);



   // Cell.nameLabel.text = [NSString stringWithFormat: @"%d", val+];


   }else{
      Cell.nameLabel.text = @"value";
   }
  NSLog(@"Position :- %ld   %d", (long)indexPath.row, position);

  return Cell;
}

This is the code for picker view form where i get value;

  - (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
 {

    [self.mytableview reloadData];
    [self hidePickerView];
    NSLog(@"row selected:%ld", (long)row);
    value = _countingarray[row];

 }

-(void)viewDidLoad
{
  value = @"0";
}

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
  NSLog(@"row selected:%ld", (long)row);
  value = [NSString stringWithFormat:@"%d",[value intval] + [_countingarray[row] intval]];
  [self.mytableview reloadData];
  [self hidePickerView];

}   


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *identifier = @"Cell";

    UitableviewcellTableViewCell *Cell = [tableView dequeueReusableCellWithIdentifier:identifier forIndexPath:indexPath];
    Cell.nameLabel.text = value;
    NSLog(@"%@", value);
    return Cell;
}
