How to make a custom UISearchController datasource?

[cityofangels]

I have a universal iOS app. The iPhone version has a search view that has a UISearchDisplayController. The iPad app has a custom UI that essentially does the same thing.

I want to make a class that handles all the searching stuff that I can use for both the iPad and iPhone. Can anyone give me any guidance as to how to get started? Do I need to subclass NSObject that handles this stuff? I think its just as simple as adding the methods there then calling them from the two view controllers?

I have the iPhone version working so all I need to do is abstract the search code to this new class.

Couldn't you just use the same view controller 'UISearchDisplayController' in the iPad view? There may be some small modifications to handle the iPad view but you should be able to use the same controller.

The iPad has a completely custom UI actually. It looks like the spotlight on the iPhone.

Right now, I have this all in one class. I should be able to abstract the second method into its own class so I can call it from both the iPhone and iPad view controllers.

- (void)searchBarSearchButtonClicked:(UISearchBar *)iSearchBar {
    [self performSearchForString:iSearchBar.text];
}


- (void)performSearchForString:(NSString *)iSearchString {
    self.hideTable = NO;
    self.isSearching = YES;
    [self.searchDisplayController.searchResultsTableView reloadData];
    
    NSArray *aFilteredArray = [self.currentScopeArray filteredArrayUsingPredicate:self.searchScopePredicate];
    self.masterArray = [NSMutableArray arrayWithObjects:[NSNull null], [NSNull null], [NSNull null], [NSNull null], nil];
    for (NSInteger x = 0; x < aFilteredArray.count; x++) {
        NSMutableDictionary *aPostBody = [NSMutableDictionary dictionaryWithCapacity:3];
        NSDictionary *aScopeDictionary = [aFilteredArray objectAtIndex:x];
        NSString *aSearchType = [aScopeDictionary objectForKey:@"searchType"];
        [aPostBody setObject:iSearchString forKey:@"searchTerm"];
        [aPostBody setObject:aSearchType forKey:@"searchType"];
        
        ISTServiceRequest *aFormRequest = [ISTServiceRequest post:[[CMAConfiguration sharedConfiguration] endpointForKey:@"search"] body:aPostBody requestDidFinishBlock:^(ISTServiceRequestReceipt *aReceipt) {
            if (aReceipt.responseObject && [aReceipt.responseObject isKindOfClass:[NSArray class]]) {
                NSArray *aResultsArray = aReceipt.responseObject;
                Class aSearchObjectType = nil;
                if ([aSearchType isEqualToString:@"GUEST"] || [aSearchType isEqualToString:@"MEMBER"]) {
                    aSearchObjectType = [CMACustomer class];
                }  else if ([aSearchType isEqualToString:@"RESERVATION"] || [aSearchType isEqualToString:@"PICKUP"]) {
                    aSearchObjectType = [CMAReservation class];
                }
                [self.masterArray replaceObjectAtIndex:aReceipt.tag withObject:[aSearchObjectType objectsFromServerDictionaries:aResultsArray]];
                [self stopAnimationAtSection:aReceipt.tag];
            }
        }];
        aFormRequest.tag = x;
    }
}

Actually I may have gotten some of it done.

My iPhone VC now just has this:

- (void)performSearchForString:(NSString *)iSearchString {
    self.hideTable = NO;
    self.isSearching = YES;
    [self.searchDisplayController.searchResultsTableView reloadData];
    
    NSArray *aFilteredArray = [self.currentScopeArray filteredArrayUsingPredicate:self.searchScopePredicate];
    self.masterArray = [NSMutableArray arrayWithObjects:[NSNull null], [NSNull null], [NSNull null], [NSNull null], nil];
    CMASearchController *searchController = [[CMASearchController alloc]init];
    [searchController performSearchWithArray:aFilteredArray andSearchTerm:iSearchString];
    [searchController release];
}

and my search class has this:

- (void)performSearchWithArray:(NSArray *)iArray andSearchTerm:(NSString *)iSearchTerm {
    for (NSInteger x = 0; x < iArray.count; x++) {
        NSMutableDictionary *aPostBody = [NSMutableDictionary dictionaryWithCapacity:3];
        NSDictionary *aScopeDictionary = [iArray objectAtIndex:x];
        NSString *aSearchType = [aScopeDictionary objectForKey:@"searchType"];
        [aPostBody setObject:iSearchTerm forKey:@"searchTerm"];
        [aPostBody setObject:aSearchType forKey:@"searchType"];
        
        ISTServiceRequest *aFormRequest = [ISTServiceRequest post:[[CMAConfiguration sharedConfiguration] endpointForKey:@"search"] body:aPostBody requestDidFinishBlock:^(ISTServiceRequestReceipt *aReceipt) {
            if (aReceipt.responseObject && [aReceipt.responseObject isKindOfClass:[NSArray class]]) {
                NSArray *aResultsArray = aReceipt.responseObject;
                Class aSearchObjectType = nil;
                if ([aSearchType isEqualToString:@"GUEST"] || [aSearchType isEqualToString:@"MEMBER"]) {
                    aSearchObjectType = [CMACustomer class];
                }  else if ([aSearchType isEqualToString:@"RESERVATION"] || [aSearchType isEqualToString:@"PICKUP"]) {
                    aSearchObjectType = [CMAReservation class];
                }
                [self.masterArray replaceObjectAtIndex:aReceipt.tag withObject:[aSearchObjectType objectsFromServerDictionaries:aResultsArray]];
                [self stopAnimationAtSection:aReceipt.tag];
            }
        }];
        aFormRequest.tag = x;
    }
}

But how can I handle these two lines from the search class that modify attributes in the iPhone vc?

                [self.masterArray replaceObjectAtIndex:aReceipt.tag withObject:[aSearchObjectType objectsFromServerDictionaries:aResultsArray]];
                [self stopAnimationAtSection:aReceipt.tag];
