tableview - Using UIRefreshControl with UISearchBar search results

Question

I'm trying to get a behavior like the Mail app where there is a UISearchBar and you can pull to refresh the search results. Currently, I have the Search Display Controller with the UISearchBar connected in IB and everything works fine (I can refresh when in the main tableview and I can search).

But when I search and try to pull to refresh the search results (like the mail app), there is no UIRefreshControl. Check the video below:

I guess I have to make the UISearchBar the headerView of the tableView but I can't reference the UISearchBar since it's an outlet of the Search Display Controller in IB. Here is my code for the UIRefreshControl :

    //Pull to Refresh
    refreshControl = [[UIRefreshControl alloc] init];
    [refreshControl addTarget:self action:@selector(pullToRefresh)      
    forControlEvents:UIControlEventValueChanged];


    [self.carTableView addSubview:refreshControl];

I'm using the above code in the -viewDidLoad method of the UIViewController that contains the tableView

Answer 1

I solved the problem by creating another UIRefreshControl and adding it to the UISearchDispayController every time the user type a search text in the search bar which I can detect in - (void)searchDisplayController:(UISearchDisplayController *)controller didLoadSearchResultsTableView:(UITableView *)tableView . Here is the code:

//in viewDidLoad
//Pull to refresh in the search
    searchRefreshControl = [[UIRefreshControl alloc] init];
    [searchRefreshControl addTarget:self action:@selector(pullToRefresh) forControlEvents:UIControlEventValueChanged];

Then:

//in - (void)searchDisplayController:(UISearchDisplayController *)controller didLoadSearchResultsTableView:(UITableView *)tableView

//add the refresh control to the search display controller tableview
    [self.searchDisplayController.searchResultsTableView addSubview:searchRefreshControl];
