UIView TransitionFromView exemple?

-(IBAction) anAction:(id) sender {
    //assume view1 and view2 are some subviews of self.view
    //view1 will be replaced with view2 in the view hierarchy
    [UIView transitionFromView:view1 
                        toView:view2 
                      duration:0.5 
                       options:UIViewAnimationOptionTransitionFlipFromLeft   
                    completion:^(BOOL finished){
                        /* do something on animation completion */
                      }];
    }

}
