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

Updated for SWIFT 3:

Suppose that the user has entered a string in searchfield and clicks x the following code works to hide keyboard when x is pressed

`

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) 
{
            if searchBar.text == nil || searchBar.text == ""
            {
                searchBar.perform(#selector(self.resignFirstResponder), with: nil, afterDelay: 0.1)
            }
 }

Answer 2

Another point of view for clear text flow (similar to @TomSwift answer but clearer for me and less tricky). Also, I need to hide Cancel button after exit from the search bar, implement live search (after each symbol) and cover table before user complete search.

//self.searchHoverView can cover table view
//performSearchWithSearchBar: method for performing search

#pragma mark - UISearchBarDelegate

- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar {
    [searchBar setShowsCancelButton:YES animated:YES];
    self.searchHoverView.hidden = NO;
}

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {
    if (searchText.length) {
        [self performSearchWithSearchBar:searchBar];
    } else {
        UIButton *button;
        for (UIView *subView in [searchBar subviews]) {
            for (UIView *view in [subView subviews]) {
                if ([view isKindOfClass:[UIButton class]]) {
                    button = (UIButton *)view;
                    break;
                }
            }
        }

        if (button) {
            dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
                [button sendActionsForControlEvents:UIControlEventTouchUpInside];
            });
        }
    }
}

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar {
    self.searchBar.text = nil;

    [self.searchBar setShowsCancelButton:NO animated:YES];
    [self.searchBar resignFirstResponder];

    self.searchHoverView.hidden = YES;
}
