从iPhone地址簿获取电子邮件地址

问题描述：

我目前能够成功访问并从 peoplePickerNavigationController 获取数据，但我想要做的是访问联系人的电子邮件地址，然后按下联系人姓名后，模态窗口被解除。

I am currently able to successfully access and get data from the peoplePickerNavigationController, but what I would like to do is have the email address of the contact be accessed, then the modal window dismissed when the contact name is pressed.

情形：

"Button is clicked to add a contact
AddressBook Modal Window slides into view
Name of Contact is pressed
If available, the contact's email address is stored in an array
Dismiss modal window"

我目前的代码包括：

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier {
    ABMultiValueRef container = ABRecordCopyValue(person, property);
    CFStringRef contactData = ABMultiValueCopyValueAtIndex(container, identifier);
    CFRelease(container);
    NSString *contactString = [NSString stringWithString:(NSString *)contactData];
    CFRelease(contactData);

    NSLog(@"Value is: %@", contactString);

    [self dismissModalViewControllerAnimated:YES];  
    return NO;
}

答

这就是我的工作。

if(property == kABPersonEmailProperty) {
  CFTypeRef prop = ABRecordCopyValue(person, property);
  CFIndex index = ABMultiValueGetIndexForIdentifier(prop,  identifierForValue);
  NSString *email = (NSString *)ABMultiValueCopyValueAtIndex(prop, index);

  ...

  CFRelease(prop);
  [email release];
}
