Question

I want the row height to be based off the content height… so each row height is sized to fit based off the content.

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    return tableView.contentSize.height;
}

This is what i have so far but it doesn’t work.

Try this code for exmaple and also refer this http://www.icodeblog.com/2010/11/18/making-smarter-table-view-cells/  

 #define FONT_SIZE 14.0f
    #define CELL_CONTENT_WIDTH 125.0f
    #define CELL_CONTENT_MARGIN 10.0f
    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
       // static NSString *CellIdentifier = @"Cell";
        NSString *CellIdentifier = [NSString stringWithFormat:@"%d", indexPath.row] ;
        UILabel *lblTitle = nil;
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
        if (cell == nil) {
            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
            cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
            cell.selectionStyle = UITableViewCellSelectionStyleNone;




            lblTitle =[[UILabel alloc]initWithFrame:CGRectMake(5, 15, 110, 44)];
            lblTitle.backgroundColor = [UIColor clearColor];
            lblTitle.textColor = [UIColor whiteColor];
            lblTitle.font = [UIFont systemFontOfSize:11.0];
            lblTitle.tag = 1;

            UILabel *lblType =[[UILabel alloc]initWithFrame:CGRectMake(125, 0, 75, 44)];

        }

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

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