w iOS 6.1, można użyć MKLocalSearch
, część standardowego iOS MapKit.framework:
MKLocalSearchRequest *request = [[MKLocalSearchRequest alloc] init];
request.naturalLanguageQuery = @"restaurant";
request.region = mapView.region;
MKLocalSearch *localSearch = [[MKLocalSearch alloc] initWithRequest:request];
[localSearch startWithCompletionHandler:^(MKLocalSearchResponse *response, NSError *error) {
NSMutableArray *annotations = [NSMutableArray array];
[response.mapItems enumerateObjectsUsingBlock:^(MKMapItem *item, NSUInteger idx, BOOL *stop) {
CustomAnnotation *annotation = [[CustomAnnotation alloc] initWithPlacemark:item.placemark];
annotation.title = item.name;
annotation.subtitle = item.placemark.addressDictionary[(NSString *)kABPersonAddressStreetKey];
annotation.phone = item.phoneNumber;
[annotations addObject:annotation];
}];
[self.mapView addAnnotations:annotations];
}];
Moje niestandardowe adnotacji jest tylko MKPlacemark
plus tytuł i podtytuł:
@interface CustomAnnotation : MKPlacemark
@property (strong, nonatomic) NSString *title;
@property (strong, nonatomic) NSString *subtitle;
@property (strong, nonatomic) NSString *phone;
@end
Jeśli chcesz zobaczyć wskaźnik ujawnienia na swoim objaśnieniu (możesz przejść do innego kontrolera, aby wyświetlić szczegóły, możesz:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation
{
if (![annotation isKindOfClass:[CustomAnnotation class]])
return nil;
MKAnnotationView *annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation
reuseIdentifier:@"CustomAnnotationView"];
annotationView.canShowCallout = YES;
annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
return annotationView;
}
Jeśli chcesz otworzyć inny widok, gdy użytkownik kliknie na akcesorium objaśnienia:
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
if (![view.annotation isKindOfClass:[CustomAnnotation class]])
return;
CustomAnnotation *annotation = (CustomAnnotation *)view.annotation;
ABRecordRef person = ABPersonCreate();
ABRecordSetValue(person, kABPersonOrganizationProperty, (__bridge CFStringRef) annotation.title, NULL);
if (annotation.phone)
{
ABMutableMultiValueRef phoneNumberMultiValue = ABMultiValueCreateMutable(kABMultiStringPropertyType);
ABMultiValueAddValueAndLabel(phoneNumberMultiValue, (__bridge CFStringRef) annotation.phone, kABPersonPhoneMainLabel, NULL);
ABRecordSetValue(person, kABPersonPhoneProperty, phoneNumberMultiValue, nil);
CFRelease(phoneNumberMultiValue);
}
ABMutableMultiValueRef address = ABMultiValueCreateMutable(kABMultiDictionaryPropertyType);
ABMultiValueAddValueAndLabel(address, (__bridge CFDictionaryRef) annotation.addressDictionary, kABWorkLabel, NULL);
ABRecordSetValue(person, kABPersonAddressProperty, address, NULL);
ABUnknownPersonViewController *personView = [[ABUnknownPersonViewController alloc] init];
personView.unknownPersonViewDelegate = self;
personView.displayedPerson = person;
personView.allowsAddingToAddressBook = YES;
[self.navigationController pushViewController:personView animated:YES];
CFRelease(address);
CFRelease(person);
}
- (void)unknownPersonViewController:(ABUnknownPersonViewController *)unknownPersonView didResolveToPerson:(ABRecordRef)person
{
}

Googling w Google Place API – Rushabh
no..Nie mówię o miejscu Google API, że jestem w stanie pokazać go na WEBView, chcę go zaimplementować na mapach iOS –
