ios - Change the UITableViewCell Height According to Amount of Text

I need to be able to adjust the height of a single cell in my UITableView so that it fits the amount of text in its detail label.

I have played with the following but it hasn't work for me:

How do I wrap text in a UITableViewCell without a custom cell

Attempted code:

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    cell.textLabel.lineBreakMode = UILineBreakModeWordWrap;
    cell.textLabel.numberOfLines = 0;
    cell.textLabel.font = [UIFont fontWithName:@"Helvetica" size:17.0];
}

and

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *cellText = @"Go get some text for your cell.";
    UIFont *cellFont = [UIFont fontWithName:@"Helvetica" size:17.0];
    CGSize constraintSize = CGSizeMake(280.0f, MAXFLOAT);
    CGSize labelSize = [cellText sizeWithFont:cellFont constrainedToSize:constraintSize lineBreakMode:UILineBreakModeWordWrap];

    return labelSize.height + 20;
}

This hasn't worked, it shows the entire string on the cell, however the cell height isn't affected at all.

Its simple, just add this to your code:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return UITableViewAutomaticDimension;
}

It automatically count an height of row and than return a float... :-)

Hope this helps!
