SearchBar not displaying results until cancel button clicked

Question

I have implemented a UITableView with search bar (and search display) - all works fine, but the table results do not get updated until the search bar cancel button is tapped.

Delegate methods:

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
    // asynchronous request with [self.tableView reloadData] in the connectionDidFinishLoading
    [self getProductData:searchBar.text]; 
 [searchBar resignFirstResponder];
 [self.tableView reloadData];


}

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {

}

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar {

}

- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar {

}

- (void)searchBarTextDidEndEditing:(UISearchBar *)searchBar  {  
} 

- (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar {
 return YES;
}

Do I need to call a delegate method after receiving the data from the server? Or should I make the request synchronous?

Thanks

edit: I tried with a synchronous request and it still does not work!

Answer 1

Resolved this issue by adding this code to the end of my getProductData method:

[[[self searchDisplayController] searchResultsTableView] performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:NO];

Answer 2

I think you have to implement:

- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString

and return YES

See the TableSearch sample code

Answer 3

Please try something like this:

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {
    [self getProductData:searchText]; 
    [self.tableView reloadData];
}
