这让我发疯，因为它只发生在孤立数量的联系人中.

This is driving me crazy, as it only happens with an isolated number of contacts.

任何帮助将不胜感激.

这是请求的代码，非常感谢您的帮助:

Here is the code that was requested, thank you very very much for your help:

(这是我认为发生错误的方法的摘录)

(It is an extract from the method where I think the error happens)

奇怪的是，它只发生在某些联系人身上，删除联系人，然后创建一个新联系人即可解决问题...

The weird thing is that it only happens with certain contacts, and deleting the contact, then creating a new one solves the problem...

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person
                                property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier

    NSString* firstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);
    NSString* lastName = (NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);
    NSNumber* record = [NSNumber numberWithInt:ABRecordGetRecordID(person)];
    if(lastName!=nil){
        name=[NSString stringWithFormat:@"%@ %@",firstName,lastName];
    }
    else {
        name=firstName;
    }

        ABMultiValueRef phone = ABRecordCopyValue(person, property);
        NSString *value =(NSString *)ABMultiValueCopyValueAtIndex(phone, identifier);
        NSString *label =(NSString *)ABMultiValueCopyLabelAtIndex(phone, identifier);
        NSMutableArray *tempArray=[[NSMutableArray alloc] initWithArray:[[NSUserDefaults  standardUserDefaults] objectForKey:@"MainArray"]];
        NSDictionary *stringDictionary = [NSDictionary dictionaryWithObjectsAndKeys:name, kLabelKey, value, kNumberKey,label, kNumberLabelKey,record, kReferenceKey, nil];
        [tempArray addObject:stringDictionary];
        NSArray *mainArray = [NSArray arrayWithArray:tempArray];
        [[NSUserDefaults standardUserDefaults] setObject:mainArray forKey:@"MainArray"];

推荐答案

致遇到类似问题的任何人:

To anyone experiencing a similar problem:

我的错误来自于我使用的事实:

My error came from the fact that I was using:

ABMultiValueCopyValueAtIndex 带有标识符而不是索引.

ABMultiValueCopyValueAtIndex with an identifier instead of an index.

您必须调用 ABMultiValueGetIndexForIdentifier，然后在 ABMultiValueCopyValueAtIndex 上使用该索引.

You have to call ABMultiValueGetIndexForIdentifier and then use that index on the ABMultiValueCopyValueAtIndex.

最后一行是Identifier!=index.
