ObjC - UIViews: animating view and subview independently?

Question

Hi!

I have an UIView and its subview. When I animate myView (size.x+20) my subview is being animated too, however I want to translate my subview at the same time independently(origin.x-40) (without the subview moving because of the resizing of myView).

I was able to do it by adjusting the translations (or better position, because I might wanna change y later) .fromValue, .toValue and .duration to compensate movement caused by changes to myView.

UIView beginAnimations:nil context:NULL];
[myView setFrame:pVnewFrame];
[UIView commitAnimations];

CABasicAnimation *bBTranslateAnimation = [CABasicAnimation animationWithKeyPath:@"position"]; 
bBTranslateAnimation.delegate = self;
bBTranslateAnimation.fromValue = [NSValue valueWithCGPoint:CGPointMake(160, 480)];
bBTranslateAnimation.toValue = [NSValue valueWithCGPoint:CGPointMake(160, 436)];
bBTranslateAnimation.duration = 0.35;
[buttonBar addAnimation:bBTranslateAnimation forKey:@"anim"];

But that is no proper solution. Is there a good way to move view and subviews independently? (setting autoresizeSubviews and autoresizingMask doesn't help)

Thanks in advance!
