ios table with dynamic sections and two different prototype cells

Question

I am new to ios programming so bear with me if the question is simple. I have a core data table mapped to a table view controller. The data in it currently looks as follows - there is one prototype cell:

I need to sum up the data by dates and show the details of each date in a different section with the summed up total coming up as the first row. Something like:

My question is is this doable? I am thinking I need to create sections and two prototype cells within each table cell. Would appreciate quick feedback.

Thanks all!

The easy way to do this is using section headers. You can either use a single string (@"%@: %@", date, total) or a wrapper view with a label on the left for the date and on the right for the total.

-(NSString *) tableView:(UITableView *)tv titleForHeaderInSection:(NSInteger)s 
{
    NSString *dateString = [self dateStringForSection:s];
    float total = [self totalForSection:s];
    return [NSString stringWithFormat:@"%@: %0.2f", dateString, total];
}

Or

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    return [self wrappedHeaderForSection:s];
}

You'll have to implement dateStringForSection: or wrappedHeaderForSection: appropriately, of course.
