Obtain row height dynamically in UITableViewCell with multiple nibs

Question

I have a UITableView with the UITableViewCell loaded from different Nib files when the user taps or double taps a cell i.e there are three different Nib files of varying height, one each for normal, tap and double tap.

How do I identify the loaded nib within heightForRowAtIndexPath: for dynamically setting the row height?

Answer 1

You can dequeue the cell in heightForForAtIndexPath and check it's height:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *cellId = @"Cell";//set cell ID here based on your view controller's logic
    UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:cellId];
    return cell.bounds.size.height;
}

You can cache the dequeued cells in a dictionary if you're concerned about performance. There is a more detailed discussion of this approach in Retrieve custom prototype cell height from storyboard (contrary to what the title might imply, the use of storyboard is not required).
