POCLGeocoder ever return one placemark

copied!<p>I want to revive <a href="https://stackoverflow.com/questions/10417022/how-to-get-multiple-placemarks-from-clgeocoder">this</a> and <a href="https://stackoverflow.com/questions/11344188/clgeocoder-only-returning-one-placemark">this</a> question because the problem still persists for me, so I'm writing a new question.</p> <p>This is my code:</p> <pre><code>- (SVGeocoder*)initWithParameters:(NSMutableDictionary*)parameters completion:(SVGeocoderCompletionHandler)block { self = [super init]; self.operationCompletionBlock = block; Class cl = NSClassFromString(@"CLGeocoder"); if (cl != nil) { if (self.geocoder_5_1 == nil) { self.geocoder_5_1 = [[cl alloc] init]; } NSString *address = [parameters objectForKey:kGeocoderAddress]; [self.geocoder_5_1 geocodeAddressString:address completionHandler:^(NSArray *placemarks, NSError *error) { NSMutableArray *svplacemarks = [NSMutableArray arrayWithCapacity:1]; SVPlacemark *placemark; NSLog(@"placemarks[count] = %i", [placemarks count]); for (CLPlacemark *mark in placemarks) { placemark = [[SVPlacemark alloc] initWithPlacemark:mark]; [svplacemarks addObject:placemark]; } self.operationCompletionBlock([NSArray arrayWithArray:svplacemarks],nil,error); }]; } else { self.operationRequest = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://maps.googleapis.com/maps/api/geocode/json"]]; [self.operationRequest setTimeoutInterval:kSVGeocoderTimeoutInterval]; [parameters setValue:@"true" forKey:kGeocoderSensor]; [parameters setValue:[[NSLocale currentLocale] objectForKey:NSLocaleLanguageCode] forKey:kGeocoderLanguage]; [self addParametersToRequest:parameters]; self.state = SVGeocoderStateReady; } return self; } </code></pre> <p>It is my personal version (quite rough) of SVGeocoder using CLGeocoder for forward geocoding with retrocompatibility for iOS < 5.1</p> <p>I use this solution because of the Google terms which prevent the use of the maps API without showing the result on a Google map.</p> <p>The problem is the same one from the previously mentioned questions: CLGeocoder returns only one placemark and the log prints a nice</p> <blockquote> <p>"placemarks[count] = 1".</p> </blockquote> <p>My question is, does anyone know if there is another way to retrieve forward geocoding, or some other magic thing (the Apple map app shows multiple markers for the same query I do, "via roma", for example) ?</p> <hr> <p>EDIT FOR ROB'S SOLUTION</p> <pre><code>Class mkLocalSearch = NSClassFromString(@"MKLocalSearch"); if (mkLocalSearch != nil) { NSString *address = [parameters objectForKey:kGeocoderAddress]; MKLocalSearchRequest *request = [[MKLocalSearchRequest alloc] init]; request.region = MKCoordinateRegionForMapRect(MKMapRectWorld); request.naturalLanguageQuery = address; MKLocalSearch *localsearch = [[MKLocalSearch alloc] initWithRequest:request]; [localsearch startWithCompletionHandler:^(MKLocalSearchResponse *response, NSError *error) { NSMutableArray *svplacemarks = [NSMutableArray arrayWithCapacity:1]; SVPlacemark *placemark; NSLog(@"response.mapItems[count] = %i", [response.mapItems count]); for (MKMapItem *item in response.mapItems) { placemark = [[SVPlacemark alloc] initWithPlacemark:item.placemark]; [svplacemarks addObject:placemark]; } self.operationCompletionBlock([NSArray arrayWithArray:svplacemarks],nil,error); }]; } </code></pre> <p>This is an interesting solution that gives another point of view. Unfortunately, even if I set the region to worldwide, I still get a nice log</p> <blockquote> <p>response.mapItems[count] = 1</p> </blockquote> <p>The query was "via roma", which is a very common street name in Italy, so much so that I think we can find it in practically any Italian city.</p> <p>Maybe I'm doing something wrong?</p> <hr> <p>EDIT 2 - New Test:</p> <p>convert World Rect to CLRegion, code from <a href="https://gist.github.com/esromneb/3402711" rel="nofollow noreferrer">here</a></p> <pre><code> NSString *address = [parameters objectForKey:kGeocoderAddress]; // make a conversion from MKMapRectWorld to a regular CLRegion MKMapRect mRect = MKMapRectWorld; MKMapPoint neMapPoint = MKMapPointMake(MKMapRectGetMaxX(mRect), mRect.origin.y); MKMapPoint swMapPoint = MKMapPointMake(mRect.origin.x, MKMapRectGetMaxY(mRect)); float ewDelta= neMapPoint.x - swMapPoint.x; float nsDelta= swMapPoint.y - neMapPoint.y; MKMapPoint cMapPoint = MKMapPointMake(ewDelta / 2 + swMapPoint.x, nsDelta / 2 + neMapPoint.y); CLLocationCoordinate2D neCoord = MKCoordinateForMapPoint(neMapPoint); CLLocationCoordinate2D swCoord = MKCoordinateForMapPoint(swMapPoint); CLLocationCoordinate2D centerCoord = MKCoordinateForMapPoint(cMapPoint); CLLocationDistance diameter = [self getDistanceFrom:neCoord to:swCoord]; // i don't have the map like showed in the example so i'm trying to center the search area to the hypothetical center of the world CLRegion *clRegion = [[CLRegion alloc] initCircularRegionWithCenter:centerCoord radius:(diameter/2) identifier:@"worldwide"]; [self.geocoder_5_1 geocodeAddressString:address inRegion: clRegion completionHandler:^(NSArray *placemarks, NSError *error) { NSMutableArray *svplacemarks = [NSMutableArray arrayWithCapacity:1]; SVPlacemark *placemark; NSLog(@"placemarks[count] = %i", [placemarks count]); for (CLPlacemark *mark in placemarks) { placemark = [[SVPlacemark alloc] initWithPlacemark:mark]; [svplacemarks addObject:placemark]; } self.operationCompletionBlock([NSArray arrayWithArray:svplacemarks],nil,error); }]; </code></pre> <p>... and I get the usual "placemark [count] = 1"</p>
