You override tableView:heightForRowAtIndexPath: and in there calculate the height of the content based on the size it will be when rendered in your chosen font:

So, something like this:

- (CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
   NSString *content = [self.contentArray objectAtIndex:indexPath.row];

   // Max size you will permit
   CGSize maxSize = CGSizeMake(200, 1000);
   CGSize size = [content sizeWithFont:font constrainedToSize:maxSize lineBreakMode:NSLineBreakByWordWrapping];
   return size.height + 2*margin;
}

I found I needed to add some padding, hence the 'margin' variable above. Note that the code above constrains the text to a width of 200px, which you may not want.
