How about something like this:

    [UIView beginAnimations:@"PartialPageCurlEffect" context:nil];
    [UIView setAnimationDuration:0.3];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:myOldSubViewController.view cache:YES];

    [myOldSubViewController.view addSubview:myNewViewController.view];

    [UIView commitAnimations];
