You can use one view controller to present another view controller modally on top of it.

[currentViewController presentModalViewController:viewControllerToPresentInModalWindow
                                         animated:YES];

By default, the modal view controller will be full-screen, but you can change the size to one of two other presets.

[viewControllerToPresentInModalWindow setModalPresentationStyle:UIModalPresentationPageSheet];

[viewControllerToPresentInModalWindow setModalPresentationStyle:UIModalPresentationFormSheet];

Additionally, you can set the transition used to display the modal window on screen by using setModalTransitionStyle:.

The screenshot posted above is not using any of these presets; as the other commenters mentioned, it is a custom modal window that doesn't leverage UIKit's built-in modal functionality.
