iPad UIActionSheet - Not displaying the last added button

Question

I'm trying to display a UIActionSheet from my iPad. Here's the code that I'm using:

-(void) presentMenu {
    UIActionSheet *popupMenu = [[UIActionSheet alloc] initWithTitle:@"Menu" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:nil];
    for (NSString *option in _menuItems) {
        [popupMenu addButtonWithTitle:option];
    }
    popupMenu.actionSheetStyle = UIActionSheetStyleBlackOpaque;
    if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
        [popupMenu showFromTabBar:_appDelegate.tabBar.tabBar];
    }
    else if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
        [popupMenu showFromBarButtonItem:self.navigationItem.rightBarButtonItem animated:YES];
    }
    [popupMenu release];
    return;
}

The iPhone version of the program displays all the buttons in _menuItems, but the iPad version just ignores the last item from that array. Does anyone know why this might be happening?

Thanks,
Teja.

Answer 1

Found the answer as soon as I typed out this post. Somehow removing the "Cancel" button causes both the buttons to come up. Weird.

EDIT: Although, this is really annoying because all my button indices change between the iPhone and the iPad versions (The iPhone still needs the cancel button). How do I handle this?
