The code from Brenton didn't work for me so I did a little more digging through the apple docs and found this piece of code for an horizontal flip:

- (IBAction)toggleMainViews:(id)sender {
    [UIView transitionFromView:(displayingPrimary ? primaryView : secondaryView)
                        toView:(displayingPrimary ? secondaryView : primaryView)
                      duration:1.0
                       options:(displayingPrimary ? 
                                    UIViewAnimationOptionTransitionFlipFromRight :
                                    UIViewAnimationOptionTransitionFlipFromLeft)
                    completion:^(BOOL finished) {
                                   if (finished) {
                                       displayingPrimary = !displayingPrimary;
                                   }
                              }
    ];
}

You can do a vertical flip by changing the options from UIViewAnimationOptionTransitionFlipFromRight : UIViewAnimationOptionTransitionFlipFromLeft to UIViewAnimationOptionTransitionFlipFromTop : UIViewAnimationOptionTransitionFlipFromBottom.

Worked like a charm.
