Question

I am a total newbie in the ipad app development.

I am interested in creating an application where i have a popover showing a tableview with list of items. Then i select an item and the view drills to another tableview consisting of another list of items and a navigate back button as well.

the level to which i would be drilling down is dynamic.

Please guide me with appropriate resources to help me solve the problem.

I did it before and it works well!
Just assign this function to your button (perhaps an UIBarButtonItem):

UIPopoverController *popover;
bool isPopoverOpen = false;
-(void)openPopover{
    if(!isPopoverOpen){
        FirstViewController *firstViewCtrl = [[PartsViewCtrl alloc] init];
        UINavigationController *navbar = [[UINavigationController alloc] initWithRootViewController:firstViewCtrl];
        [firstViewCtrl release];
        navbar.contentSizeForViewInPopover = CGSizeMake(TABLE_WIDTH, TABLE_HEIGHT);
        popover = [[UIPopoverController alloc] initWithContentViewController:navbar];
        [navbar release];
        popover.delegate = self;
        popover.popoverContentSize = CGSizeMake(TABLE_WIDTH, TABLE_HEIGHT);
        [popoverOnPartsView presentPopoverFromBarButtonItem:barButtonItem permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
        isPopoverOpen = true;
    }else{
        [popover dismissPopoverAnimated:YES];
        [popover release];
        isPopoverOpen = false;
    }
}

And implement this function to FirstViewController which has an UITableView:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    SecondViewController *secondViewController = [[SecondViewController alloc] init];
    [self.navigationController pushViewController:secondViewController animated:YES];
    [secondViewController release];
}

Now you can add an UITableView to SecondViewController, Too. And use this scenario for other tables!

I hope it works for you!
