I crated a zoom animation using CGAffineTransformScaleMake,
[UIView beginAnimations:nil context:view];
[UIView setAnimationDuration: 0.4f];
[UIView setAnimationDelegate: self];
view.transform = CGAffineTransformMakeScale(scale, scale);
CGSize zoomViewSize = viewForZooming.frame.size;
view.frame = CGRectMake(0, 0, zoomViewSize.width, zoomViewSize.height);
scrollView.contentSize = zoomViewSize;
scrollView.contentOffset = centerPoint;
[UIView commitAnimations];
But everytime I zoom out, my content view will just jump to the left most part of the view. How can I make the view stay its position when zooming out?
Thanks.

You should not try and set the transform of a UIScrollView manually; instead, use the zoomScale property, or the -zoomToRect:animated: method.
