ABRecordRef检查记录是否仅限Facebook？

Question

当在所有地址簿联系人中循环时，有一种方法可以查看记录是否是仅限Facebook的记录？这是在iOS设置中添加Facebook时插入的地址簿记录。

我想跳过这些记录，只查看用户输入或从其他来源同步的记录。

谢谢

每ABPerson记录属于一个ABSource。

当您遍历所有人员记录时，请分别拨打ABPersonCopySource(person)。 Facebook记录应该全部与特定的源记录相关联。我不知道如何识别它：可能该源记录的kABSourceNameProperty将包含“Facebook”。

有了这个snipplet可以检测的Facebook的联系人：

+ (BOOL)isPersonFacebookContact:(ABRecordRef)person { 
    ABMultiValueRef instantMessage = ABRecordCopyValue(person, kABPersonInstantMessageProperty); 

    BOOL returnValue = NO; 

    if (instantMessage) { 
     for (NSInteger i=0 ; i < ABMultiValueGetCount(instantMessage); i++) { 
      CFDictionaryRef instantMessageValue = ABMultiValueCopyValueAtIndex(instantMessage, i); 
      CFStringRef instantMessageString = CFDictionaryGetValue(instantMessageValue, kABPersonInstantMessageServiceKey); 

      if (CFStringCompare(instantMessageString, kABPersonInstantMessageServiceFacebook, 0) == kCFCompareEqualTo) { 
       returnValue = YES; 
      } 

      CFRelease(instantMessageString); 
      CFRelease(instantMessageValue); 
     } 
    } 

    CFRelease(instantMessage); 

    return returnValue; 
}

这似乎为我工作，它并不直接检测的Facebook，但你可以进一步评估的来源和是有链接的社会知名度那就是脸书，和facebook联系人的链接联系人，那么你会非常确定这是它的脸书。我用它只获取我可以写回的联系人。用户可以更改他们的默认联系人创建帐户，但基于我的测试Facebook只有联系人来源永远不会匹配ABAddressBookCopyDefaultSource。

CFArrayRef people = ABAddressBookCopyArrayOfAllPeopleInSource(ab , kABSourceTypeLocal); 
AllContacts = CFArrayCreateMutableCopy(kCFAllocatorDefault, CFArrayGetCount(people), people); 


// Remove all the contacts that we cant write back to 
for (int i = CFArrayGetCount(AllContacts)-1; i >-1 ; i--) 
{ 
    ABRecordRef person = CFArrayGetValueAtIndex(AllContacts, i); 
    if((ABPersonCopySource(person) !=ABAddressBookCopyDefaultSource(ab))) 
    { 
     NSString *fName = (NSString *)CFBridgingRelease(ABRecordCopyValue(person, kABPersonFirstNameProperty)); 
     NSString *lName = (NSString *)CFBridgingRelease(ABRecordCopyValue(person, kABPersonLastNameProperty)); 

     DLog(@"Removed a read only contact %@ %@", fName , lName); 
     CFArrayRemoveValueAtIndex(AllContacts, i); 
    }// else its not something you can write back to, like facebook, twitter. 
    CFRelease(person); 

}

新版本（无内存舔）：

+ (BOOL)isPersonFacebookContact:(ABRecordRef)person { 
    ABMultiValueRef instantMessage = ABRecordCopyValue(person, kABPersonInstantMessageProperty); 

    BOOL returnValue = NO; 

    if (instantMessage) { 
     for (NSInteger i = 0; i < ABMultiValueGetCount(instantMessage); i++) { 
      CFDictionaryRef instantMessageValue = ABMultiValueCopyValueAtIndex(instantMessage, i); 
      CFStringRef instantMessageString = CFDictionaryGetValue(instantMessageValue, kABPersonInstantMessageServiceKey); 

      if (instantMessageString) { 
       if (CFStringCompare(instantMessageString, kABPersonInstantMessageServiceFacebook, 0) == kCFCompareEqualTo) { 
        returnValue = YES; 
       } 
      } 
      CFRelease(instantMessageValue); 
     } 

     CFRelease(instantMessage); 
    } 

    return returnValue; }
