Question

I have a UISearchBar and a UISearchBarDisplayController set up by a xib.
After a search with no result it says “No result” some lines down in the table.
How to modify default text?

Answer 1

@interface ClassName : UIViewController {
    UILabel                     *noResultLabel;
    UISearchDisplayController   *searchController;
}

@implementation ClassName

- (id) init {
    // bla bla bla bla
    // some more bla
    // setup your UISearchDisplayController and stuffz
    noResultLabel = nil;
}

- (void) changeNoResultsText:(NSString *)text {
    if (noResultLabel == nil) {
        for (id subview in searchController.searchResultsTableView.subviews) {
            if ([subview isKindOfClass:[UILabel class]]) {
                if ([((UILabel *)subview).text isEqualToString:@"No Results"]) {
                    if (noResultLabel == nil) noResultLabel = subview;
                }
            }
        }
    }

    if (noResultLabel != nil) noResultLabel.text = text;
}

- (void)searchBarSearchButtonClicked:(UISearchBar *)bar { 
    [self changeNoResultsText:@"Searching..."];
}

- (BOOL) searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString {
    [self changeNoResultsText:@"Searching full search..."];
    return YES;
}
