iPhone: Flipping View like the Weather App?

Can someone advise the codes or similar codes for the iPhone weather page, when you touch the little circled (i) the 开发者_StackOverflow中文版right, bottom corner, it flips the page.

Thanks.

What the weather app does is: it just presents a modal view controller, but sets the transition style to a different value. The following assumes the controller you want to show is simply named "controller" and shows the controllers view similarly to the weather app.

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