objective-c - 如何为 MKPlacemark 创建 addressDictionary？

Question

    placemark = [[MKPlacemark alloc]initWithCoordinate:storedCoordinate addressDictionary:addressDict];

我尝试创建字典以用于上面的代码，但没有任何效果:(

    NSDictionary *addressDict = [[NSDictionary alloc] initWithObjectsAndKeys:
    location.countryCode, @"CountryCode",
    location.country,@"kABPersonAddressCountryKey", 
    location.state, kABPersonAddressStateKey, 
    location.city, @"City",
    location.street, kABPersonAddressStreetKey,
    location.zip, kABPersonAddressZIPKey,
    nil];

在为 MKPlacemark 创建 addressDictionary 时，建议您使用 ABPerson 中定义的“地址属性”常量。请注意，由于这些常量是 CFStringRef 类型，因此您需要将它们转换为 (NSString *) 以便将它们用作 NSDictionary 中的键。

NSDictionary *addressDict = @{
                              (NSString *) kABPersonAddressStreetKey : location.street,
                              (NSString *) kABPersonAddressCityKey : location.city,
                              (NSString *) kABPersonAddressStateKey : location.state,
                              (NSString *) kABPersonAddressZIPKey : location.zip,
                              (NSString *) kABPersonAddressCountryKey : location.country,
                              (NSString *) kABPersonAddressCountryCodeKey : location.countryCode
                              };

iOS 9+ 更新:使用新的联系人框架

NSDictionary *addressDict = @{
                              CNPostalAddressStreetKey : location.street,
                              CNPostalAddressCityKey : location.city,
                              CNPostalAddressStateKey : location.state,
                              CNPostalAddressPostalCodeKey : location.zip,
                              CNPostalAddressCountryKey : location.country,
                              CNPostalAddressISOCountryCodeKey : location.countryCode
                              };
