Question

I create a UIViewController with a UITableView and UISearchDisplayController, the problem is that shouldReloadTableForSearchString not run...this is my code, where is the mistake for you?
- (void)viewDidLoad {
[super viewDidLoad];
array = [[NSMutableArray alloc] initWithObjects:#"ciao",#"mandi",#"viva",#"blabla", nil];
arrayFiltrato = [[NSMutableArray alloc] initWithObjects:#"ciao",#"mandi",#"viva",#"blabla", nil];
//[self.tableView setContentOffset:CGPointMake(0, 44.f) animated:NO];
[self.tableView reloadData];
[self setSearchBar];
}
- (void) viewWillAppear:(BOOL)animated {
[super viewWillAppear:YES];
[self.navigationController setNavigationBarHidden: NO];
}
- (void) setSearchBar {
self.searchBar = [[UISearchBar alloc] init];
[self.searchBar setAutocapitalizationType:UITextAutocapitalizationTypeNone];
[self.searchBar setPlaceholder:#"Type a search term" ];
[self.searchBar setTintColor:[UIColor blackColor]];
[self.searchBar setDelegate:self];
[self.searchBar sizeToFit];
[self.tableView setTableHeaderView:self.searchBar];
self.searchDisplay = [[UISearchDisplayController alloc] initWithSearchBar:self.searchBar contentsController:self];
[self.searchDisplay setSearchResultsDataSource:self];
[self.searchDisplay setSearchResultsDelegate:self];
[self.searchDisplay setDelegate:self];
}

The problem is that the delegate method is wrong, isn't this:
- (BOOL)searchDisplay:(UISearchDisplayController *)controller shouldRelo....
but this:
- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldRelo...
