How to get a UITableView row height to auto-size to the size of the UITableViewCell?

So assuming I'm creating the UITableViewCell in Interface Builder, and it height is more than the standard size, how can I get the UITableView row height to autosize to it? (i.e. as opposed to manually having to measure the height in interface builder and than programmatically setting it)

http://www.cimgf.com/2009/09/23/uitableviewcell-dynamic-height/ is a great tutorial for this.

The main bit is

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath; {   // Get the text so we can measure it   NSString *text = [items objectAtIndex:[indexPath row]];   // Get a CGSize for the width and, effectively, unlimited height   CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);   // Get the size of the text given the CGSize we just made as a constraint   CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];   // Get the height of our measurement, with a minimum of 44 (standard cell size)   CGFloat height = MAX(size.height, 44.0f);   // return the height, with a bit of extra padding in   return height + (CELL_CONTENT_MARGIN * 2); }
