【问题描述】：

我必须在我的应用程序中显示来自 facebook 的联系人。我不知道如何执行此操作。 我正在使用此代码，但没有得到任何联系人列表。我在数组中得到了这种类型，但没有得到任何 facebook 联系人列表。

<__NSArrayM 0x608000457430>(

请帮忙。

if (&ABAddressBookRequestAccessWithCompletion)  // if in ios 6

        // Request authorization to Address Book
        ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL);

        if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) 
            ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) 
                [self getFacebookContacts:addressBookRef];
            );
        
        else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) 
            [self getFacebookContacts:addressBookRef];
        
        else 
            // The user has previously denied access
            // Send an alert telling user to change privacy setting in settings app
        
    
    else // if not in iOS 6

        ABAddressBookRef addressBookRef = ABAddressBookCreate();
        [self getFacebookContacts:addressBookRef];
        NSLog(@"Not ios 6");
    


-(void) getFacebookContacts:(ABAddressBookRef) addressBookRef

    CFArrayRef allContacts = ABAddressBookCopyArrayOfAllPeople(addressBookRef);
    CFIndex contactCount = CFArrayGetCount(allContacts);
    // Traverse through contacts
    for(int i=0; i<contactCount; i++)
    
        ABRecordRef ref = CFArrayGetValueAtIndex(allContacts, i);
        //Check if contact has social profile
        ABMultiValueRef social = ABRecordCopyValue(( ABRecordRef)ref, kABPersonSocialProfileProperty);
        if (social) 
            // *****   This is coming as 0     **********
            CFIndex count = ABMultiValueGetCount(social);
            for (int i = 0 ; i < count; i++) 
                CFDictionaryRef socialValue = ABMultiValueCopyValueAtIndex(social, i);
                if(CFStringCompare( CFDictionaryGetValue(socialValue, kABPersonSocialProfileServiceKey), kABPersonSocialProfileServiceFacebook, 0)==kCFCompareEqualTo) 
                    NSLog(@"Facebook Contact %d : %@",i, (NSString*) CFDictionaryGetValue(socialValue, kABPersonSocialProfileUserIdentifierKey));
                
            
        
    

【参考方案1】：

没有运行以下代码，但尝试根据需要进行一些更改。

-(void) getFacebookContacts:(ABAddressBookRef) addressBookRef

    CFArrayRef allContacts = 
    ABAddressBookCopyArrayOfAllPeople(addressBookRef);
    CFIndex contactCount = CFArrayGetCount(allContacts);
    CFStringRef str1 = CFSTR("FACEBOOK");

    // Traverse through contacts
    for(int i=0; i<contactCount; i++)
    
        ABRecordRef ref = CFArrayGetValueAtIndex(allContacts, i);
        //Check if contact has social profile
        ABMultiValueRef social = ABRecordCopyValue(( ABRecordRef)ref, kABPersonSocialProfileProperty);

        if (social) 
        for (NSInteger i=0 ; i < ABMultiValueGetCount(social); i++) 
            CFDictionaryRef instantMessageValue = ABMultiValueCopyValueAtIndex(social, i);
            CFStringRef instantMessageString = CFDictionaryGetValue(instantMessageValue, kABPersonInstantMessageServiceKey);
            // Check if service is FACEBOOK
            if (CFStringCompare(instantMessageString, str1, 0) == kCFCompareEqualTo) 
            returnValue = YES;

            NSDictionary * powerDic = (__bridge NSDictionary *)instantMessageValue;
            NSLog(@"%@", [powerDic valueForKey:@"service"]);
            NSLog(@"%@", [powerDic valueForKey:@"url"]);
            NSLog(@"%@", [powerDic valueForKey:@"username"]);
            NSLog(@"%@", [powerDic valueForKey:@"displayname"]);

        
      
    

希望这会有所帮助:) 编辑：经过测试并正常工作。

【讨论】：

它也不起作用，如果（社会）得到 nil 没有进入（NSInteger i=0 ; i

这就是我们想要的，对吧？如果social为nil，则无需执行以下代码。

但是 CFArrayRef allContacts 有 42 个元素

@user7356913：我已经编辑了代码。我试过了，它工作正常，检查并告诉我。

instantMessage 这是什么，未声明的标识符和返回值 @Tejas K
