objective-c - 将 Twitter 帐户添加到 ABRecordRef(人员)的最简单方法

Question

所以我需要将一个 Twitter 帐户添加到 ABRecordRef 中。然而，最快的方法似乎是获取社交资料属性的多值引用，创建它的可变版本，查找它是否有 Twitter 条目，如果已​​经有，则创建可变副本字典并用新字典替换它。否则，使用 twitter 键和用户名创建一个新的字典条目。

实际上它非常冗长:

   ABRecordRef person;

   ABMultiValueRef oldsocials = ABRecordCopyValue(abperson, kABPersonSocialProfileProperty);
   ABMutableMultiValueRef newsocials;
   if(oldsocials){
      newsocials = ABMultiValueCreateMutableCopy(oldsocials);
   } else {
      newsocials = ABMultiValueCreateMutable(kABMultiDictionaryPropertyType);
   }

   CFIndex socialsCount = ABMultiValueGetCount(socials);

   bool foundtwitter = false;

   for (int k=0 ; k<socialsCount ; k++) {
      CFDictionaryRef socialValue = (CFDictionaryRef)ABMultiValueCopyValueAtIndex(socials, k);
      if(socialValue){
         if(CFStringCompare( (CFStringRef)CFDictionaryGetValue(socialValue, kABPersonSocialProfileServiceKey), kABPersonSocialProfileServiceTwitter, 0)==kCFCompareEqualTo) {

            CFMutableDictionaryRef tomutate = CFDictionaryCreateMutableCopy(socialValue);

            CFDictionarySetValue(tomutate, kABPersonSocialProfileUsernameKey, toNS(thetwitter));

            ABMultiValueReplaceValueAtIndex(socials, tomutate, k);

            CFRelease(tomutate);

            foundtwitter = true;
         }

         CFRelease(socialValue);
      }

      if(foundtwitter)
         break;

   }


   if(!foundtwitter){
    ABMultiValueAddValueAndLabel(newsocials, [NSDictionary dictionaryWithObjectsAndKeys:
                                          (NSString *)kABPersonSocialProfileServiceTwitter, kABPersonSocialProfileServiceKey,
                                          @"justinbieber", kABPersonSocialProfileUsernameKey,
                                          nil], kABPersonSocialProfileServiceTwitter, NULL);
   }


    ABRecordSetValue(abperson, kABPersonSocialProfileProperty, newsocials, NULL);

   if(oldsocials)
      CFRelease(oldsocials);

   CFRelease(newsocials);

加twitter其实挺长的，感觉自己哪里做错了。我的意思是，理想情况下，在另一种语言上添加类似的东西将接近于此:

person["socialServices"]["twitter"] = "@SomeUserName";
person.save();

我是不是漏掉了什么？

看看下面我的 friend ，对于 facebook 和 twitter - 它会起作用:

 //adding social
ABMultiValueRef social = ABMultiValueCreateMutable(kABMultiDictionaryPropertyType);
ABMultiValueAddValueAndLabel(social, (__bridge CFTypeRef)([NSDictionary dictionaryWithObjectsAndKeys:
                                                           (NSString *)kABPersonSocialProfileServiceTwitter, kABPersonSocialProfileServiceKey,
                                                           [tempVCard objectForKey:@"twitterUserName"], kABPersonSocialProfileUsernameKey,
                                                           nil]), kABPersonSocialProfileServiceTwitter, NULL);
ABMultiValueAddValueAndLabel(social, (__bridge CFTypeRef)([NSDictionary dictionaryWithObjectsAndKeys:
                                                           (NSString *)kABPersonSocialProfileServiceFacebook, kABPersonSocialProfileServiceKey,
                                                           [tempVCard objectForKey:@"facebookUserName"], kABPersonSocialProfileUsernameKey,
                                                           nil]), kABPersonSocialProfileServiceFacebook, NULL);

ABRecordSetValue(person, kABPersonSocialProfileProperty, social, NULL);
CFRelease(social);

我的私有(private)数组“tempVCard”将是您的用户动态数据数组。
