[searchResults removeAllObjects];

self.tableView.allowsMultipleSelectionDuringEditing = YES;


NSString *searchString = searchController.searchBar.text;
for(NSUInteger i =0; i < titles.count; i++){
    NSDictionary *titleAndIndex = [NSDictionary dictionaryWithObjectsAndKeys:
                                   [titles objectAtIndex:i], @"title",nil];
    [searchResults addObject:titleAndIndex];
    //      NSLog(@"filteredArray2: %@", titleAndIndex);



}
[searchResults filterUsingPredicate:[NSPredicate
                                     predicateWithFormat:@"title contains[c] %@",searchString]];
dispatch_async(dispatch_get_main_queue(), ^{
    [self.tableView reloadData];


});
}
