POSearchDisplayController searching in multiple arrays

copied!<p>Okay, after long searching, hesitating and more searching I just can't seem to figure this out.</p> <p>I have a SearchDisplayController, and I have four different arrays where I am searching in using NSPredicate, because each UITableViewCell is made out of 4 strings (title, description etc.).</p> <p>I now have 4 search-arrays, search_title, search_description etc which are filled like this:</p> <pre><code>- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope { NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:@"SELF contains[cd] %@", searchText]; self.search_category = [self.temp_category filteredArrayUsingPredicate:resultPredicate]; self.search_producttitle = [self.price_producttitle filteredArrayUsingPredicate:resultPredicate]; self.search_type = [self.price_type filteredArrayUsingPredicate:resultPredicate]; self.search_description = [self.price_description filteredArrayUsingPredicate:resultPredicate]; </code></pre> <p>When I use NSLog (array count), I can see it's working because it gives the correct count of each array when I enter a search term.</p> <p>My tableview cell looks like this:</p> <pre><code>if ([tableView isEqual:self.searchDisplayController.searchResultsTableView]){ cell.selectionStyle = UITableViewCellSelectionStyleNone; cell.nameLabel.text = [self.search_producttitle objectAtIndex:[[searchResults objectAtIndex:indexPath.row] integerValue]]; cell.priceLabel.text = [self.search_price objectAtIndex:[[searchResults objectAtIndex:indexPath.row] integerValue]]; cell.descrLabel.text = [self.search_description objectAtIndex:[[searchResults objectAtIndex:indexPath.row] integerValue]]; cell.IDLabel.text = [self.search_type objectAtIndex:[[searchResults objectAtIndex:indexPath.row] integerValue]]; } else{ cell.selectionStyle = UITableViewCellSelectionStyleNone; cell.nameLabel.text = [price_producttitle objectAtIndex:indexPath.row]; cell.IDLabel.text = [price_type objectAtIndex:indexPath.row]; cell.priceLabel.text = [price objectAtIndex:indexPath.row]; cell.descrLabel.text = [price_description objectAtIndex:indexPath.row]; </code></pre> <p>Maybe you can already see what I'm trying to do. I'm now making new arrays from the old arrays, which I call search arrays. However, those arrays are independent from each other (one array may be empty while the other is filled with researchresults). I need to know from which index the data is, that is stored in those searcharrays. If i know that the data in search_producttitle comes from indexes 1,3 and 4 from price_producttitle (the original array), then I can use those numbers for indexPath.row to show. At least, that's my plan for now, making a searchResult array containing numbers which should be used in the objectAtIndex when making the cell.</p> <p>I'm struggling with this, I can't find any examples where they are searching within multiple arrays because the cells are made up by multiple arrays.</p> <p>Can someone please give me a hint in the good direction, or examples which I can use?</p> <p>Thank you in advance.</p> <p>Prastow</p> <p>References I used:</p> <p><a href="https://stackoverflow.com/questions/8169889/searchdisplaycontroller-search-multiple-arrays">SearchDisplayController search multiple arrays</a></p> <p><a href="http://ygamretuta.me/2011/08/10/ios-implementing-a-basic-search-uisearchdisplaycontroller-and-interface-builder/" rel="nofollow noreferrer">http://ygamretuta.me/2011/08/10/ios-implementing-a-basic-search-uisearchdisplaycontroller-and-interface-builder/</a></p>
