kABPersonAddressProperty导致ABAddressBookGetPersonWithRecordID下的崩溃

+ (NSMutableArray*) getAllContactProfiles{

    NSMutableArray *listOfProfile = [[NSMutableArray alloc] init];

    //---get the contact information for the api
    ABAddressBookRef addressBook = ABAddressBookCreate(); 
    CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(addressBook);
    CFIndex numberOfPeopleInAddressBook = ABAddressBookGetPersonCount(addressBook);

    //<- Here I loop through all the contacts and pass the ABRecordRef into the following function

    //---release the variables---
    CFRelease(addressBook);
    CFRelease(people);
    [listOfProfile autorelease];

    return listOfProfile;
}

以下函数

+ (MSProfileEntry*) getPersonProfileThroughABRecordRef:(ABRecordRef) person{

    MSProfileEntry *mockProfile;
    ABRecordID recID=ABRecordGetRecordID(person);
    //get the user name
    CFStringRef firstName;
    firstName = ABRecordCopyValue(person, kABPersonFirstNameProperty);//it goes wrong here!
    CFStringRef lastName;
    lastName = ABRecordCopyValue(person, kABPersonLastNameProperty);
    //bla bla bla.. the rest of the code
}

一切都很顺利。但是,当我尝试通过ABAddressBookGetPersonWithRecordID获取ABRecordRef时,就像在下一个方法中一样:

下一种方法

+ (MSProfileEntry*) getPersonProfileThroughContactId:(NSInteger*)contactId{
    ABAddressBookRef addressBook = ABAddressBookCreate();
    ABRecordRef person = 
    ABAddressBookGetPersonWithRecordID(addressBook, (ABRecordID)contactId);
    CFRelease(addressBook);
    if (person == nil) {
        return nil;
    }
    return [MSContactUtil getPersonProfileThroughABRecordRef:person];
}

整个应用程序在线崩溃: ABRecordCopyValue(person, kABPersonFirstNameProperty);

现在的问题是 ABRecordCopyValue(person,kabbersonfirstnameproperty); ABAddressBookCopyArrayOfAllPeople ABAddressBookGetPersonWithRecordID

有人知道怎么解决这个问题吗?我真的不想只是为了寻找一个联系人而在整个联系人基础上循环。
