Set different row height in different sections (storyboard)
===

I have a tableview with multiple prototype cells that i designed in the storyboard, but i´m stuck with the height problem because my first cell is supose to be different from the second one and so on...I have different identifiers for each cell, and because i designed them in storyboard, i know they´re height´s. I have this in my code, but it´s not working, does anyone knows how to fix it?:

    -(CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
    {
    
    UITableViewCell *cell = [[UITableViewCell alloc]init];
    switch (indexPath.section) 
    
    {
        case 1:
            
            cell = [tableView dequeueReusableCellWithIdentifier:@"cell1"];
            return 743.0f; 

            break;
            
        case 2:
                
            cell = [tableView dequeueReusableCellWithIdentifier:@"cell2"];
            return 300.0f;
                
            

    }
    
    

}

Thanks for your time.
