UISearchview responding to actions - TableSearch sample iphone

I would like to modify the tableSearch sample code, so that there is no nib for the tableview. As it is already a tableviewcontroller subclass, I can call the tableview like this:

MainViewController *mainViewController = [[MainViewController alloc] initWithStyle:UITableViewStylePlain];//NibName:@"MainView" bundle:nil];

Without the nib, I would like to add the search bar manually. I tried below:

    UISearchBar* searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0,10, 320, 41)];
[searchBar setFrame:CGRectMake(0,10, 320, 41)];
searchBar.delegate = self;
searchBar.tintColor = [UIColor redColor];
[searchBar sizeToFit];
self.tableView.tableHeaderView  = searchBar;

The sear开发者_如何转开发chbar does appear ok. Now I would like the search action of this searchbar to point to the methods that I already have in my code, i.e searchDisplayController delegate methods. Is there anyway I can point the self.searchDisplayController's Search bar property to my custom searchbar, so they do the same actions? Thanks in advance...

You have to use the initWithSearchBar:contentsViewController method of UISearchDisplayController. This way, your custom search bar will be associated with the controller. Also you have to set the contentsViewController in this method.

Hm.. this is code from one of my VC. Also set UISearchBarDelegate,UISearchDisplayDelegate

_listContainer = [[UITableView alloc] init];
_listContainer.delegate = self;
_listContainer.dataSource = self;
_listContainer.separatorStyle = UITableViewCellSelectionStyleNone;
_data = [[NSArray alloc] init];

And then

_searchBar = [[NL_CustomSearchBar alloc] initWithFrame:CGRectMake(4.0f, 0, 150, 46)];
 _searchBar.delegate = self;
 _listContainer.tableHeaderView = _searchBar;
