【问题描述】：

我正在尝试弄清楚如何获取 MKPlacemark 商品的街道地址。我在控制台中打印了一个项目，我可以看到那里的信息，但我只得到 thoroughfare 信息，没有街道地址号码。

这是我的代码：

- (void)performSearch {
    MKLocalSearchRequest *request = [[MKLocalSearchRequest alloc]init];
    request.naturalLanguageQuery = _searchText.text;
    request.region = _mapView.region;

    _matchingItems = [[NSMutableArray alloc]init];

    MKLocalSearch *search = [[MKLocalSearch alloc]initWithRequest:request];
    NSLog(@"MKLocalSearch array created");

    [search startWithCompletionHandler:^(MKLocalSearchResponse *response, NSError *error) {
        if (response.mapItems.count == 0) {
            NSLog(@"No Matches Found");
        } else {
            for (MKMapItem *item in response.mapItems) {
                [_matchingItems addObject:item];
                MKPointAnnotation *annotation = [[MKPointAnnotation alloc]init];
                annotation.coordinate = item.placemark.coordinate;

                // Pull out address info from MKMapItem
                MKPlacemark *placemark = item.placemark;
                NSLog(@"Placemark info: %@", item.placemark);
                // Address details
                NSDictionary *address = placemark.addressDictionary;
                NSString *titleString = @"";
                NSString *subtitleString = @"";
                NSString *name = @"";
                NSString *thoroughfare = @"";
                NSString *state = @"";
                NSString *city = @"";
                NSString *country = @"";

                name = [address objectForKey:@"Name"] ? [address objectForKey:@"Name"] : @"";
                thoroughfare = [address objectForKey:@"Thoroughfare"] ? [address objectForKey:@"Thoroughfare"] : @"";
                state = [address objectForKey:@"State"] ? [address objectForKey:@"State"] : @"";
                city = [address objectForKey:@"City"] ? [address objectForKey:@"City"] : @"";
                country = [address objectForKey:@"Country"] ? [address objectForKey:@"Country"] : @"";

                titleString = [NSString stringWithFormat:@"%@ %@", name, thoroughfare];
                subtitleString = [NSString stringWithFormat:@"%@ %@ %@ %@", thoroughfare, state, city, country];

                // Strings for annotation
                annotation.title = item.name;
                annotation.subtitle = subtitleString;

                [_mapView addAnnotation:annotation];
            }
        }
    }];
}

【问题讨论】：

MKPlacemark 是 CLPlacemark 的子类。 CLPlacemark 为每个地址元素定义了方便的属性（因此您不必直接通过键名访问字典）。 Street# 应该在 placemark.subThoroughfare 中。但并非所有地址元素都可以保证设置。
谢谢！如果您将其设为答案，我会将其标记为您已回答。

【解决方案1】：

你可以这样找到地址：

        geocoder.reverseGeocodeLocation(location, completionHandler: {(placemarks, error)->Void in
        var placemark:CLPlacemark!

        if error == nil && placemarks!.count > 0 {
            placemark = placemarks![0] as CLPlacemark


            var addressString : String = ""
            if placemark.ISOcountryCode == "TW" /*Address Format in Chinese*/ {
                if placemark.country != nil {
                    addressString = placemark.country!
                }
                if placemark.subAdministrativeArea != nil {
                    addressString = addressString + placemark.subAdministrativeArea! + ", "
                }
                if placemark.postalCode != nil {
                    addressString = addressString + placemark.postalCode! + " "
                }
                if placemark.locality != nil {
                    addressString = addressString + placemark.locality!
                }
                if placemark.thoroughfare != nil {
                    addressString = addressString + placemark.thoroughfare!
                }
                if placemark.subThoroughfare != nil {
                    addressString = addressString + placemark.subThoroughfare!
                }
            } else {
                if placemark.subThoroughfare != nil {
                    addressString = placemark.subThoroughfare! + " "
                }
                if placemark.thoroughfare != nil {
                    addressString = addressString + placemark.thoroughfare! + ", "
                }
                if placemark.postalCode != nil {
                    addressString = addressString + placemark.postalCode! + " "
                }
                if placemark.locality != nil {
                    addressString = addressString + placemark.locality! + ", "
                }
                if placemark.administrativeArea != nil {
                    addressString = addressString + placemark.administrativeArea! + " "
                }
                if placemark.country != nil {
                    addressString = addressString + placemark.country!
                }

                print (placemark.postalCode)

                let new_placemark: MKPlacemark = MKPlacemark (placemark: placemark)

            print(placemark.description)    

            }


        }
    })

【解决方案2】：

MKPlacemark 是CLPlacemark 的子类。

CLPlacemark 为每个地址元素定义了方便的属性，因此您不必直接通过键名访问字典。（如果必须直接访问字典，请尝试使用预定义的ABPerson Address Property key name constants documented here。）

使用便捷的属性访问器，街道编号应为placemark.subThoroughfare。

但请注意，并非所有地址元素都保证根据给定坐标的准确性和国家/地区进行设置。
