cllocationmanager - 如何从 CLPlacemark 获取 zipCode，我知道它总是为空？

Question

这是一段示例代码：

[_geoCoder reverseGeocodeLocation:self.locationManager.location // You can pass aLocation here instead
               completionHandler:^(NSArray *placemarks, NSError *error) {

                   dispatch_async(dispatch_get_main_queue(),^ {
                       // do stuff with placemarks on the main thread

                       if (placemarks.count == 1) {

                           CLPlacemark *place = [placemarks objectAtIndex:0];
                          // NSLog([place postalCode]);
                          NSString* addressString1 = [place thoroughfare];
                           addressString1 = [addressString1 stringByAppendingString:[NSString stringWithFormat:@"%@",[place.addressDictionary objectForKey:(NSString*)kABPersonAddressZIPKey]]];//
                           NSLog(@"%@",addressString1);// is null ??
                           NSlog(@"%@",place.postalCode);//is null ??

                           //[self performSelectorInBackground:@selector(log) withObject:nil];
                       }

                   });
               }];

我猜你可能只有一个“坏”坐标，没有邮政编码。试试下面的代码片段。它应该在末尾显示各种信息和邮政编码“80802”：

CLLocationCoordinate2D myCoordinates = { 48.167222, 11.586111 };
CLLocation *location = [[CLLocation alloc]initWithLatitude:myCoordinates.latitude longitude:myCoordinates.longitude];

CLGeocoder *geocoder = [[CLGeocoder alloc] init];
[geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error) {
    NSLog(@"%d Placemarks %@", placemarks.count, placemarks);
    CLPlacemark *place = [placemarks objectAtIndex:0];
    NSLog(@"Placemark %@", place);
    NSLog(@"Address Dictionary: %@", place.addressDictionary);
    NSLog(@"Zip key %@", [place.addressDictionary objectForKey:(NSString *)kABPersonAddressZIPKey]);

}];

在第一行插入不同的坐标并自己试验。
