iphone - 当 recordId 不可用时，ABAddressBookGetPersonWithRecordID 使应用程序崩溃

Question

在我的应用程序中，我已存储ABPropertyID在数据库中，并基于此显示了数量，ABRecordRef但是ABAddressBookGetPersonWithRecordID(addressBook, recordID).当在联系人中删除联系人并尝试获取ABRecordRef时，应用程序崩溃是显而易见的。

所以我的问题是：

有什么方法可以检查地址簿中的记录 ID 是否可用？

Answer 1

此函数不会抛出异常，但如果没有具有此 ID 的记录，则返回 NULL。

试试这个

ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL);

if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
    ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {
        // First time access has been granted, add the contact
        ABAddressBookRef iPhoneAddressBook = ABAddressBookCreateWithOptions(NULL, NULL);

        ABRecordRef newPerson = ABPersonCreate();

        ABRecordSetValue(newPerson, kABPersonSortByFirstName,(__bridge CFTypeRef)(firstname),&error);
        ABRecordSetValue(newPerson, kABPersonLastNameProperty,(__bridge CFTypeRef)(lastname), &error);
        ABRecordSetValue(newPerson, kABPersonOrganizationProperty, @"", &error);
        ABRecordSetValue(newPerson, kABPersonJobTitleProperty,@"", &error);



        ABMutableMultiValueRef multiPhone = ABMultiValueCreateMutable(kABMultiStringPropertyType);
        ABMultiValueAddValueAndLabel(multiPhone, (__bridge CFTypeRef)(contact_phone), kABPersonPhoneMainLabel, NULL);
        ABMultiValueAddValueAndLabel(multiPhone, @"", kABPersonPhoneMobileLabel, NULL);
        ABMultiValueAddValueAndLabel(multiPhone, @"", kABOtherLabel, NULL);
        ABRecordSetValue(newPerson, kABPersonPhoneProperty, multiPhone,nil);
        CFRelease(multiPhone);



        ABMutableMultiValueRef multiEmail = ABMultiValueCreateMutable(kABMultiStringPropertyType);

        ABRecordSetValue(newPerson, kABPersonEmailProperty, multiEmail, &error);

        //        ABMutableMultiValueRef multiAddress = ABMultiValueCreateMutable(kABMultiDictionaryPropertyType);
        //    NSMutableDictionary *addressDictionary = [[NSMutableDictionary alloc] init];

        //    ABRecordSetValue(newPerson, kABPersonAddressProperty, multiAddress,&error);
        //    CFRelease(multiAddress);

        ABAddressBookAddRecord(iPhoneAddressBook, newPerson, &error);
        ABAddressBookSave(iPhoneAddressBook, &error);

        if (error != NULL)
        {
            NSLog(@"Danger Will Robinson! Danger!");
        }


        // ABAddressBookRef addressBook = ABAddressBookCreate();


    });
}
else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {

    alertvalue++;
