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).

Answer 1

Use the UIViewAnimationOptionLayoutSubviews option:

[UIView animateWithDuration:.25
                      delay:0
                    options:UIViewAnimationOptionLayoutSubviews
                 animations:^{
                     CGRect frame = searchBar.frame;
                     frame.size.width = newWidth;
                     searchBar.frame = frame;
                 } completion:nil
 ];

Answer 2

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)

Answer 3

Try this:

[UIView animateWithDuration:0.3 animations:^{
    self.searchDisplayController.searchBar.frame = CGRectMake(0, 200, 320, 44);
}];
