ios - Can't animate the frame or bounds of a UISearchBar

Question

I want to animate the position of a UISearchBar, but there's no animate effect when I change the frame or bounds property of UISearchBar(center, alpha dose animate).
It's iOS SDK 4.2, is there a bug? I'm confused...

Answer 1

The problem is that some inner search bar views forcing the resize to ignore the animation.

This worked for me -

[UIView animateWithDuration:0.2 animations:^ {
                     [searchBar setFrame:searchBarFrame];
                     [searchBar setNeedsLayout];
                 }];

Where searchBarFrame - is a frame you need to set (I save it before search bar resized first time)
