以编程方式保存联系人的地址簿图像

Question

我正在创建一个地址簿应用程序，其中所有数据都存储到服务器，当用户询问时，服务器会将所有联系人恢复到 iPhone。

我的问题是如何将图像发送到服务器以及如何恢复联系人图像，我知道我的服务器将为我提供 base64 加密格式的图像。

那么任何人都可以帮助我如何以编程方式为地址簿执行图像保存和检索

你需要在nsdata中转换base64图像，然后你可以将它设置为一个联系人，在下面的代码中检查“ABPersonSetImageData”。

ABRecordSetValue(newPerson, kABPersonOrganizationProperty,data.name, &error);

        ABMutableMultiValueRef multiURL = ABMultiValueCreateMutable(kABMultiStringPropertyType);
        ABMultiValueAddValueAndLabel(multiURL, homePageURL, kABPersonHomePageLabel, NULL);
        ABRecordSetValue(newPerson, kABPersonURLProperty, multiURL,&error);
        CFRelease(multiURL);

        ABMutableMultiValueRef multiPhone = ABMultiValueCreateMutable(kABMultiStringPropertyType);
        ABMultiValueAddValueAndLabel(multiPhone, contactNumber, kABPersonPhoneMobileLabel, NULL);
        ABRecordSetValue(newPerson, kABPersonPhoneProperty, multiPhone,&error);
        CFRelease(multiPhone);

        ABMutableMultiValueRef multiEmail = ABMultiValueCreateMutable(kABMultiStringPropertyType);
        ABMultiValueAddValueAndLabel(multiEmail, emailIDs, kABHomeLabel, NULL);
        ABRecordSetValue(newPerson, kABPersonEmailProperty, multiEmail, &error);
        CFRelease(multiEmail);

        ABMutableMultiValueRef multiAddress = ABMultiValueCreateMutable(kABMultiDictionaryPropertyType);
        NSMutableDictionary *addressDictionary = [[NSMutableDictionary alloc] init];
        [addressDictionary setObject:toAddress forKey:(NSString *) kABPersonAddressStreetKey];
        [addressDictionary setObject:@"Amsterdam" forKey:(NSString *) kABPersonAddressCityKey];
        [addressDictionary setObject:@"Amsterdam" forKey:(NSString *) kABPersonAddressStateKey];
        [addressDictionary setObject:@"00000" forKey:(NSString *) kABPersonAddressZIPKey];
        [addressDictionary setObject:@"Netharland" forKey:(NSString *) kABPersonAddressCountryKey];
        ABMultiValueAddValueAndLabel(multiAddress, addressDictionary, kABHomeLabel, NULL);
        ABRecordSetValue(newPerson, kABPersonAddressProperty, multiAddress,&error);
        CFRelease(multiAddress);

        NSData *data1 = UIImagePNGRepresentation([UIImage imageNamed:data.titleImg]);
        ABPersonSetImageData(newPerson, data1, &error);


        ABAddressBookAddRecord(iPhoneAddressBook, newPerson, &error);
        ABAddressBookSave(iPhoneAddressBook, &error);
