如何從ABPeoplePicker獲取用戶選擇的電子郵件地址？

Question

Stackoverflow上的其他人發佈了一種從聯繫人列表中獲取用戶所選電話號碼的方法。可以做電子郵件地址，如果是的話，我該怎麼做？下面是代碼：

- (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; 
}

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; 
}
