IPhone : Use Adaptive Layout programmatically to resize static cells height for hCompact

In a portait-only word game I use static cells to display an IAP store:

You can see my problem in the iPhone 4 screenshot above - the pink button (to watch video ads and receive 150 coins) at the bottom is not visible.

Here is my Xcode screenshot (please click for fullscreen):

I use 7 static cells - for everything, including the Back button at the top and the status text label (not visible) - an resize the cells with this method:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    if ([indexPath row] == 0)
        return 70;

    if ([indexPath row] == 1)
        return 35;

    return 90; // XXX how to change this to 70 for hCompact?
}

My question is: how to resize the cells height programmatically for devices with compact height (called hCompact in Adaptive Layout).
