You can create a viewcontroller and then add the UIPickerView inside the controller and then use:

[self presentModalViewController:viewControllerWithPickerView animated:YES];

or you can add your UIPickerView not hidden but with a y value bigger than the screen, like 480.0 or bigger and then use UIView animations to move the UIPickerView from that position to a position visible on the screen, that would emulate the ModalViewController animation.
