Any issues if we use individual cell identifier for each Cell in UITableView-iPhone

In the below code i have used individual cell identifier for each cell,Which works well.

-(UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath {
   NSString *identifier =[NSString stringWithFormat:@"ID_%d",indexPath.row];
   UITableViewCell *cell = [self.tv dequeueReusableCellWithIdentifier:identifier];

   if(cell==nil)
   {
      UITableViewCell *cell = [self.tv dequeueReusableCellWithIdentifier:identifier];
      cell.textLabel.text=@"data";
   }
   return cell;

}

Any Performance,Memory or any other problem, in the below code?

Performance issues without a doubt. The whole point of the cell identifier is that a table view can re-use existing cells quickly rather than creating (and storing) new ones for each row.

The cell idents should be specific to the type of cell. If you have a table view with three 'types' of cell then use three idents.

If you use individual identifier, then the cells will not be reused. Each UITableViewCell will be different.

And in your code, if cell == nil, then again you are calling deque... If there is no cell with identifier, then you have to allocate a new UITableViewCell.
