dynamic UITableViewCell height

I am trying to get my cell to dynamicly change height depending on how much text is in the cell.. Currently I have the words wrapping.. but as soon as there is to much content for the cell (if it goes to a 3rd line) you cannot see anything past the 2nd line.

This is what I have so far.. hopefully someone can see if I am missing something or doing something wrong... any help would be appreciated.

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UILabel *label = nil;

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

        label = [[UILabel alloc] initWithFrame:CGRectZero];
        [label setLineBreakMode:UILineBreakModeWordWrap];
        [label setMinimumFontSize:FONT_SIZE];
        [label setNumberOfLines:0];
        [label setFont:[UIFont systemFontOfSize:FONT_SIZE]];
        [label setTag:1];

        [[cell contentView] addSubview:label];
    }

     //    //Display cells with data that has been sorted from startSortingTheArray
NSArray *keys = [self.letterDictionary objectForKey:[self.sectionLetterArray objectAtIndex:indexPath.section]];
NSString *key = [keys objectAtIndex:indexPath.row];

CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);

CGSize size = [key sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

if (!label)
    label = (UILabel*)[cell viewWithTag:1];

[label setText:key];
[label setFrame:CGRectMake(CELL_CONTENT_MARGIN, CELL_CONTENT_MARGIN, CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), MAX(size.height, 44.0f))];






//Applise current key value to cell text label
//cell.textLabel.text = key;
return cell;
}

//Cell size for word wrapping.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
{

    //Display cells with data that has been sorted from startSortingTheArray
    NSArray *keys = [self.letterDictionary objectForKey:[self.sectionLetterArray objectAtIndex:indexPath.section]];
    NSString *key = [keys objectAtIndex:indexPath.row];

    NSLog(@"%@", key);

    CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);

    CGSize size = [key sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

    CGFloat height = MAX(size.height, 44.0f);

    return height + (CELL_CONTENT_MARGIN * 2);
}

Update the code above is now a working version.. for me anyway :)

Start over and follow this tutorial word for word and you'll be fine: Cocoa is My Girlfriend

It actually looks like you looked at this tutorial and only followed part of it. I still don't see you setting the frame of the label though.
