UIVIew Flip Vertical Animation - iphone

Question

Given:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
[UIView setAnimationDuration:.5];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:card cache:NO];
myPic = [UIImage UIImagenamed: #"mySecondImage.png"];
[UIView commitAnimations];[/CODE]
Which animates 'myPic' right to left with a flip.
I need to get the same animation, but vertically. Flip from Top or Flip from Bottom. I looked around, no one really had a working model suggested.
I tried this, yet, no luck:
float duration = .5;
CABasicAnimation* animation = [CABasicAnimation animationWithKeyPath:#"transform.rotation.x"];
animation.fromValue = [NSNumber numberWithDouble:0.0f * M_PI];
animation.toValue = [NSNumber numberWithDouble:1.0f * M_PI];
animation.duration = duration;
animation.removedOnCompletion = NO;
animation.fillMode = kCAFillModeBoth;
animation.repeatCount =1;;
animation.beginTime = CACurrentMediaTime();
animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
card.layer.anchorPoint = CGPointMake(0.5, 1.0);
[card.layer addAnimation:animation forKey:#"rotationX"];[/CODE]
Any input?
Thanks in advance.

I've also needed flip from bottom animation. I've compiled couple solutions and this works for me
- (CATransform3D) makeRotationAndPerspectiveTransform:(CGFloat) angle {
CATransform3D transform = CATransform3DMakeRotation(angle, 1.0f, 0.0f, 0.0f);
transform.m34 = 1.0 / -500;
return transform;
}
- (void) flipFromBottom {
//setup firstView to be visible
view1.layer.transform = CATransform3DMakeRotation(0, 1.0f, 0.0f, 0.0f);
view1.hidden = NO;
// setup secondView to be partialy rotated and invisible
view2.layer.transform = [self makeRotationAndPerspectiveTransform:M_PI/2];
view2.hidden = YES;
// making sure that both views have the same position
view2.frame = view1.frame;
CFTimeInterval duration = 2.0;
[UIView animateWithDuration:duration/2
delay:0
options:UIViewAnimationCurveEaseIn
animations:^{
view1.layer.transform = [self makeRotationAndPerspectiveTransform:-M_PI / 2];
}
completion:^(BOOL finished){
view1.hidden = YES;
view2.hidden = NO;
[UIView animateWithDuration:duration /2
delay:0
options:UIViewAnimationCurveEaseOut
animations:^{
view2.layer.transform = CATransform3DMakeRotation(0.0f, 1.0f, 0.0f, 0.0f);
}
completion:NULL];
}];
}
