Switching views - iPhone development

I need help figuring out how to change out the view in my application. I have a wonderfully working view that I have finished and now I'd like to be able to switch the view to a brand new, blank white screen to display.

I have these files: HelloAppDelegate.h, HelloAppDelegate.m, HelloViewController.h, and HelloViewController.m

Then, I added a new View Controller so now I have two more files: SecondViewController.h and SecondViewController.m

In my first view (HelloViewController), I have a button. When the user presses this button, I'd like SecondViewController to show up. So, in my HelloViewController.m, I have an action method

-(IBAction)switchToSecondView:(id)sender {
}

In this method, how can I go about initializing my second view and displaying it?

Thanks in advance!

If you want to do something like flipping view, making it modal and then returning back to the main view do following:

Define a delegate to indicate that secondary view finished its work

@protocol FlipsideViewControllerDelegate
    - (void)flipsideViewControllerDidFinish; 
@end

In main view do following:

- (void)flipsideViewControllerDidFinish {
    [self dismissModalViewControllerAnimated:YES];
}

- (IBAction)showInfo {    

    FlipsideViewController *controller = [[FlipsideViewController alloc] initWithNibName:@"FlipsideView" bundle:nil];
    controller.delegate = self;

    controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    [self presentModalViewController:controller animated:YES];

    [controller release];
}

In secondary view do following:

- (IBAction)done {
    [self.delegate flipsideViewControllerDidFinish];    
}
