我的场景是从iPhone的通讯录中选择联系人，并将其姓名和第一个电话号码显示在文本字段中，同时以编程方式添加电话号码到其KABOtherLabel属性中。
我正在使用以下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...");
}
}
这段代码运行得非常完美。
我正在使用以下代码来选择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;
}
这段代码也完美地运行了，我在所需的文本字段中获取了值。
然而，当我将这两个代码组合起来时，即在displayPerson()方法的末尾编写以下代码或从shouldContinueAfterSelectingPerson中调用它时
我用来添加现有联系人详细信息的代码如下：
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;
问题在于，只有这个号码被添加到联系人中，所有其他现有的条目都被删除了。也就是说，这个号码覆盖了所有其他现有的条目。请帮忙解决。
