This system bug remains in iOS 8, and the accept answer's solution doesn't work anymore. So, you should use the following solution:

-(void)searchDisplayController:(UISearchDisplayController *)controller didHideSearchResultsTableView:(UITableView *)tableView {
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];
}

-(void)searchDisplayController:(UISearchDisplayController *)controller willShowSearchResultsTableView:(UITableView *)tableView {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
}

-(void)keyboardWillHide:(NSNotification*)notification {
    CGFloat height = [[[notification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size.height;
    UITableView *tableView = [[self searchDisplayController] searchResultsTableView];
    UIEdgeInsets inset;
    [[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0 ? (inset = UIEdgeInsetsMake(0, 0, height, 0)) : (inset = UIEdgeInsetsZero);
    [tableView setContentInset:inset];
    [tableView setScrollIndicatorInsets:inset];
}

Answer 2

I had this exact problem. The solution posted on the developer forums here worked for me. Not sure if it's a bug in iOS 7 or just that they changed the way they're doing things but this is the only solution that I found solved my problem.

Solution from the forum post for the lazy:

- (void)searchDisplayController:(UISearchDisplayController *)controller didHideSearchResultsTableView:(UITableView *)tableView {

    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];

}



- (void)searchDisplayController:(UISearchDisplayController *)controller willShowSearchResultsTableView:(UITableView *)tableView {

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide) name:UIKeyboardWillHideNotification object:nil];

}



- (void) keyboardWillHide {

    UITableView *tableView = [[self searchDisplayController] searchResultsTableView];

    [tableView setContentInset:UIEdgeInsetsZero];

    [tableView setScrollIndicatorInsets:UIEdgeInsetsZero];

}
