ABRecordRef檢查記錄是否僅限Facebook？

Question

當在所有地址簿聯繫人中循環時，有一種方法可以查看記錄是否是僅限Facebook的記錄？這是在iOS設置中添加Facebook時插入的地址簿記錄。

我想跳過這些記錄，只查看用戶輸入或從其他來源同步的記錄。

謝謝

每ABPerson記錄屬於一個ABSource。

當您遍歷所有人員記錄時，請分別撥打ABPersonCopySource(person)。 Facebook記錄應該全部與特定的源記錄相關聯。我不知道如何識別它：可能該源記錄的kABSourceNameProperty將包含「Facebook」。

有了這個snipplet可以檢測的Facebook的聯繫人：

+ (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; 
}

這似乎爲我工作，它並不直接檢測的Facebook，但你可以進一步評估的來源和是有鏈接的社會知名度那就是臉書，和facebook聯繫人的鏈接聯繫人，那麼你會非常確定這是它的臉書。我用它只獲取我可以寫回的聯繫人。用戶可以更改他們的默認聯繫人創建帳戶，但基於我的測試Facebook只有聯繫人來源永遠不會匹配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（無內存舔）：

+ (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; }
