iphone - 当我从经度和纬度创建位置字符串时，为什么在 iOS 中会出现此链接器错误？

Question

我有来自位置管理器的经度和纬度，现在我正在尝试反向地理编码，以将该信息转换为地址字符串。我找到了下面的代码，据称可以执行此操作，但我遇到了链接器错误。我认为这意味着我缺少一些框架或其他东西。我找不到答案。谁能帮忙？

错误:

Apple Mach-O Linker Error
"_KABPersonAddressZIPKey", referenced from:

对于我尝试生成的每个字符串，依此类推。

 CLGeocoder *geocoder = [[CLGeocoder alloc] init];
 CLLocation *newLocation = [[CLLocation alloc]initWithLatitude:latitude
                                                        longitude:longitude];
            [geocoder reverseGeocodeLocation:newLocation completionHandler:^(NSArray *placemarks, NSError *error)

            {  
                       if (error) {
                           NSLog(@"Geocode failed with error: %@", error);
                           return;
                       }

                       if (placemarks && placemarks.count > 0)
                       {
                           CLPlacemark *placemark = placemarks[0];

                           NSDictionary *addressDictionary = placemark.addressDictionary;

                           NSString *address = [addressDictionary objectForKey:(NSString *)kABPersonAddressStreetKey];
                           NSString *city = [addressDictionary objectForKey:(NSString *)kABPersonAddressCityKey];
                           NSString *state = [addressDictionary objectForKey:(NSString *)kABPersonAddressStateKey];
                           NSString *zip = [addressDictionary  objectForKey:(NSString *)kABPersonAddressZIPKey];

                           NSLog(@"%@ %@ %@ %@", address,city, state, zip);

                       }
            }
    ];

在文档中查找 kABPersonAddressStreetKey:

http://developer.apple.com/library/ios/#documentation/AddressBook/Reference/ABPersonRef_iPhoneOS/Reference/reference.html

它在顶部说它在 AddressBook 框架中。所以你需要链接到那个。
