Dismissing keyboard from UISearchBar when the X button is tapped

Question

I\'m using the UISearchBar (but not the SearchDisplayController that\'s typically used in conjunction) and I\'d like to dismiss the keyboard when you hit the \'X\' button.

Answer 1

Shouldn't UI changes be made on the main thread instead of using performselector:WithObject:afterDelay:?

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
    if (searchText.length == 0) {
        [searchBar performSelectorOnMainThread:@selector(resignFirstResponder) withObject:nil waitUntilDone:NO];
    }
}
