UISegmentedControl detail view controller

[smithms]

I have a tableview with detailview which loads data from a plist. On the detail view I have added a UISegmentedControl into the navigationItem.rightBarButtonItem with up and down arrow images. I want to advance to the next detail/row (without going back to the RootViewController table view) when the the "down" arrow is clicked and go to the previous detail/row when the "up" arrow is clicked. How would I go about doing that?

Thank you.

RootViewController.m

// Override to support row selection in the table view.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    
	if (indexPath.section==0){
			
		InfoViewController *controller = [[InfoViewController alloc] initWithNibName:@"InfoViewController" bundle:[NSBundle mainBundle]];
		controller.title =@"My Title";
		[self.navigationController pushViewController:controller animated:YES];
		[controller release];
		
	}		
	if (indexPath.section==1){
		
	
		DetailViewController *controller = [[DetailViewController alloc] 
                                        initWithDvdData:[dao libraryItemAtIndex:indexPath.row]
                                        nibName:@"DetailViewController" bundle:[NSBundle mainBundle]];
		
		NSLog(@"%d", indexPath.row);
				
		//controller.title = [[dao libraryItemAtIndex:indexPath.row] valueForKey:@"title"];
		controller.title = [NSString stringWithFormat:@"Movement #%@", [[dao libraryItemAtIndex:indexPath.row] valueForKey:@"movementnumber"]];
		[self.navigationController pushViewController:controller animated:YES];
		[controller release];  
	
	}
	
	
	
}

DetailViewController.m

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
	
	// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
	// self.navigationItem.rightBarButtonItem = self.editButtonItem;
	
	
	// Segmented Control - Custom right bar button with a view
	UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:
											[NSArray arrayWithObjects:
											 [UIImage imageNamed:@"up.png"],
											 [UIImage imageNamed:@"down.png"],
											 nil]];
	
	[segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
	
	segmentedControl.frame = CGRectMake(0, 0, 70, 30);
	segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
	segmentedControl.momentary = YES;
			
	UIBarButtonItem *segmentBarItem = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
	[segmentedControl release];
	
	self.navigationItem.rightBarButtonItem = segmentBarItem;
	[segmentBarItem release];

 titleLabel.text = [dvdData valueForKey:@"title"];

// etc....

Do something when the segmented control is clicked (go to the next or previous record)

- (void)segmentAction:(id)sender
{
	UISegmentedControl* segCtl = sender;
	// the segmented control was clicked, handle it here 
	
	if([segCtl selectedSegmentIndex]==0){
		NSLog(@"You clicked the up arrow - the segment clicked was %d", [segCtl selectedSegmentIndex]);
	}else {
		
		NSLog(@"You clicked the down arrow - the segment clicked was %d", [segCtl selectedSegmentIndex]);
		
	}
