How to create TWO Search Display IPAD

Question

I want to place two Search display in one view controller(iPad). I drag two Search Display Controller in my view controller, however, only one search display works.

In the Connections Inspector, I find that one search display's outlet "searchDisplayController" is connected to "Search Display Controller", however the other one did not have this connection. I think that's why only one search display works.

My question is that: How can we use two search display in one view controller? I think my method: drag two Search Display Controller may be incorrect.

PS. I use the following code to determine which search display is focused.

- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar {
    if (searchBar == self.customerTelSearchBar) {
        telSearchEditing = YES;
        addressSearchEditing = NO;
    }else if(searchBar == self.addressSearchBar){
        telSearchEditing = NO;
        addressSearchEditing = YES;
    }    
    return YES;
}

Always do not work with storyboard, however when I use programmatic implementation of two Search display, it works. I post here my code:

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Init customerSearchDisplayController
    self.customerTelSearchBar.delegate = self;
    customerSearchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:self.customerTelSearchBar contentsController:self];
    customerSearchDisplayController.delegate = self;
    customerSearchDisplayController.searchResultsDataSource = self;
    customerSearchDisplayController.searchResultsDelegate = self;
    // Init addressSearchDisplayController
    self.addressSearchBar.delegate = self;
    addressSearchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:self.addressSearchBar contentsController:self];
    addressSearchDisplayController.delegate = self;
    addressSearchDisplayController.searchResultsDataSource = self;
    addressSearchDisplayController.searchResultsDelegate = self;
    // SearchBar status
    telSearchEditing = NO;
    addressSearchEditing = NO;
}

-(void)filterTelForSearchText:(NSString*)searchText {
    [filtredCustomersArray removeAllObjects];
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF.tel contains[c] %@",searchText];
    filtredCustomersArray = [NSMutableArray arrayWithArray:[allCustomersArray filteredArrayUsingPredicate:predicate]];
}

-(void)filterAddressForSearchText:(NSString*)searchText {
    [filtredAddressArray removeAllObjects];
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF.address contains[c] %@",searchText];
    filtredAddressArray = [NSMutableArray arrayWithArray:[allAddressArray filteredArrayUsingPredicate:predicate]];
}

-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString {
    if (telSearchEditing) {
        [self filterTelForSearchText:searchString];
    }else if (addressSearchEditing){
        [self filterAddressForSearchText:searchString];
    }
        return YES;
}

- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar {
    if (searchBar == self.customerTelSearchBar) {
        telSearchEditing = YES;
        addressSearchEditing = NO;
    }else if(searchBar == self.addressSearchBar){
        telSearchEditing = NO;
        addressSearchEditing = YES;
    }
    return YES;
}
