Question

我的方案是从iPhone的地址簿中选择一个联系人，并将其名称和第一个电话号码显示在文本字段中，同时以编程方式在其KABOtherLabel属性中添加电话号码。

我正在使用此代码以编程方式添加联系人;

-(IBAction)addContactToAddressBook:(id)sender
{
    CFErrorRef error = NULL;

    ABAddressBookRef iPhoneAddressBook = ABAddressBookCreateWithOptions(NULL, NULL);

    ABRecordRef newPerson = ABPersonCreate();

    ABRecordSetValue(newPerson, kABPersonFirstNameProperty, (__bridge CFTypeRef)(contactName.text), &error);


   ABMutableMultiValueRef multiPhone = ABMultiValueCreateMutable(kABMultiStringPropertyType);
ABMultiValueAddValueAndLabel(multiPhone, (__bridge CFTypeRef)(phoneNumber.text), kABPersonPhoneMobileLabel, NULL);
   ABMultiValueAddValueAndLabel(multiPhone, @"1-123-456-7890", kABPersonPhoneIPhoneLabel, NULL);
   ABMultiValueAddValueAndLabel(multiPhone, @"1-987-654-3210", kABOtherLabel, NULL);

   ABRecordSetValue(newPerson, kABPersonPhoneProperty, multiPhone,nil);
   CFRelease(multiPhone);

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

  if (error != NULL)
  {

    NSLog(@"Some error...");

  }

}

此代码完美无缺。

我使用以下代码来接收联系人并将其显示在文本字段中;

-(IBAction)pickContact:(id)sender
{
    ABPeoplePickerNavigationController *picker =

    [[ABPeoplePickerNavigationController alloc] init];

    picker.peoplePickerDelegate = self;

    [self presentViewController:picker animated:YES completion:nil];
}

//called when user presses the cancel button in the Address book view controller

- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker

{
    [self dismissViewControllerAnimated:YES completion:nil];
}


//called when user pics up a contact from the phone's address book

- (BOOL)peoplePickerNavigationController:

 (ABPeoplePickerNavigationController *)peoplePicker

      shouldContinueAfterSelectingPerson:(ABRecordRef)person {


    [self displayPerson:person]; //calls displayPerson:(ABRecordRef)person to show contact's information in the app

    [self dismissViewControllerAnimated:NO completion:NULL];
}






- (void)displayPerson:(ABRecordRef)person
{
    NSString* name = (__bridge_transfer   NSString*)ABRecordCopyValue(person,kABPersonFirstNameProperty); //Extracts the contact's first name from address book & assigns it to a string value
    //NSString* lastName = (__bridge_transfer NSString*)ABRecordCopyValue(person,kABPersonLastNameProperty); //Extracts the contact's last name from address book & assigns it to a string value

    self.contactName.text = name;

    NSString* phone = nil;

    //Extracts the first phone number among multiple contact numbers from address book & assigns it to a string value
   ABMultiValueRef phoneNumbers = ABRecordCopyValue(person,kABPersonPhoneProperty);

    if (ABMultiValueGetCount(phoneNumbers) > 0)
    {
      phone = (__bridge_transfer NSString*)

      ABMultiValueCopyValueAtIndex(phoneNumbers, 0);

    }
    else
   {
       phone = @"[None]";
   }

   self.phoneNumber.text = phone;




}

此代码也很完美，我在所需的文本字段中获取值。

然而，当我将这两个代码组合起来时，i-e在displayPerson（）方法的末尾写下面的代码，或者从shouldContinueAfterSelectingPerson中调用它

我在现有联系人中添加细节的代码如下：

   CFErrorRef error = NULL;

   ABAddressBookRef myAddressBook = ABAddressBookCreateWithOptions(NULL, NULL);



   ABMutableMultiValueRef multiPhone = ABMultiValueCreateMutable(kABMultiStringPropertyType);

   ABMultiValueAddValueAndLabel(multiPhone, @"1-987-654-3210", kABPersonPhoneIPhoneLabel, NULL);

   ABRecordSetValue(person, kABPersonPhoneProperty, multiPhone,nil);
   CFRelease(multiPhone);

   ABAddressBookAddRecord(myAddressBook, person, &error);
   ABAddressBookSave(myAddressBook, &error);

   if (error != NULL)
   {

     NSLog(@"Some error");

   }

   return NO;

}

问题是只有这个号码被添加到联系人中，并且所有其他现有条目都被删除。这个号码会覆盖所有其他现有条目。请帮忙

Answer 1

ABRecordSetValue() 将记录的属性设置为您提供的值，覆盖所述属性的任何现有值。由于您使用ABMultiValueCreateMutable()创建新的空值列表，因此您实际上会忽略kABPersonPhoneProperty上可能已存在的ABRecord的任何值。

相反，您编辑现有记录的过程应为：

在所选记录上调用ABRecordCopyValue()以获取现有值列表
致电ABMultiValueCreateMutableCopy()以获取可变值列表
使用ABMultiValueAddValueAndLabel()
使用ABRecordSetValue()

从iPhone的地址簿中选择一个联系人并添加一个新的电话号码
