    copied!<p>I've a problem with my <code>UISearchDisplayController</code>, the search is not working properly.</p> <p>This is my code:</p> <pre><code> - (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope { [self.searchResults removeAllObjects]; for (int i = 0; i &lt; [temp_category count]; i++) { BOOL foundResult = FALSE; if ([[temp_category objectAtIndex:i] rangeOfString:searchText].location != NSNotFound) { foundResult = TRUE; } if ([[price_producttitle objectAtIndex:i] rangeOfString:searchText].location != NSNotFound) { foundResult = TRUE; } if ([[price_type objectAtIndex:i] rangeOfString:searchText].location != NSNotFound) { foundResult = TRUE; } if ([[price_description objectAtIndex:i] rangeOfString:searchText].location != NSNotFound) { foundResult = TRUE; } if (foundResult) { NSNumber *result = [NSNumber numberWithInt:i]; if ([self searchResults] == nil) { NSMutableArray *array = [[NSMutableArray alloc] init]; [self setSearchResults:array]; [array release]; } [searchResults addObject:result]; } } NSLog (@"array = %i", [searchResults count]); NSLog(@"%@",searchResults); } -(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString { [self filterContentForSearchText:searchString scope:[[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]]; return YES; } - (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchScope:(NSInteger)searchOption { [self filterContentForSearchText:[self.searchDisplayController.searchBar text] scope:[[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:searchOption]]; return YES; } </code></pre> <p>But I'm still confused, because when I start a search with the first letter, it gives the correct hits. But when I enter the second letter, it only shows one result (while there are more, as far as I know from my data sample). I'm doing something incorrectly. I think it has something to do with when the user enters text, but I'm confused which method I should use.</p> <p>The code I now have is a combination of: <a href="http://ygamretuta.me/2011/08/10/ios-implementing-a-basic-search-uisearchdisplaycontroller-and-interface-builder/" rel="nofollow noreferrer">this</a> tutorial and <a href="https://stackoverflow.com/questions/8169889/searchdisplaycontroller-search-multiple-arrays">this</a> SO question.</p> <p>Can someone give me a hint in the good direction? Displaying the results is fine, only this aspect bothers me. I think it has something to do with firing the method and <code>[self.searchResults removeAllObjects];</code>.</p>
