Question

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

我尝试创建用于上面代码的字典，但没有任何作用：（

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

为MKPlacemark创建addressDictionary时，建议您使用ABPerson中定义的“Address Property”常量。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
                              };

值得注意的是，您需要将“AddressBook.framework”添加到项目构建设置中。也可以在标题（.h文件）中导入：

#import <AddressBook/AddressBook.h>

然后在您的实现（.m文件）中，您可以使用：

(NSString*)kABPersonAddressStreetKey
(NSString*)kABPersonAddressCityKey
(NSString*)kABPersonAddressStateKey
(NSString*)kABPersonAddressCountryKey
