ios - 如何从 ABPeoplePicker 获取用户选择的电子邮件地址？

Question

Stackoverflow 上的其他人发布了一种从联系人列表中获取用户选择的电话号码的方法。可以为电子邮件地址完成，如果可以，我该怎么做？这是代码：

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
{
    if (property == kABPersonPhoneProperty) {
        ABMultiValueRef multiPhones = ABRecordCopyValue(person, kABPersonPhoneProperty);
        for(CFIndex i = 0; i < ABMultiValueGetCount(multiPhones); i++) {
            if(identifier == ABMultiValueGetIdentifierAtIndex (multiPhones, i)) {
                CFStringRef phoneNumberRef = ABMultiValueCopyValueAtIndex(multiPhones, i);
                CFRelease(multiPhones);
                NSString *phoneNumber = (__bridge NSString *) phoneNumberRef;
                CFRelease(phoneNumberRef);
                _contactNumber.text = [NSString stringWithFormat:@"%@", phoneNumber];
            }
        }
    }

    [self dismissViewControllerAnimated:YES completion:nil];
    return NO;
}

实现如下

- (BOOL)peoplePickerNavigationController:
        (ABPeoplePickerNavigationController *)peoplePicker
        shouldContinueAfterSelectingPerson:(ABRecordRef)person
        property:(ABPropertyID)property
        identifier:(ABMultiValueIdentifier)identifier 
{
    ABMultiValueRef emails = ABRecordCopyValue(person, property);
    CFIndex ix = ABMultiValueGetIndexForIdentifier(emails, identifier);
    CFStringRef email = ABMultiValueCopyValueAtIndex(emails, ix);
    NSLog(@"%@", email); // do something with the email here
    if (email) CFRelease(email);
    if (emails) CFRelease(emails);
    [self dismissViewControllerAnimated:YES completion:nil];
    return NO;
}
