iPhone ABPeoplePickerNavigationController - How to select two single entries of two different multivalue properties of a person from Addressbook

Question

I'm near desperation as I search for a solution for weeks now.

The Problem is simple:

• Via the ABPeoplePickerNavigationController (as a ModalView), a person should be selected.
• Then only (e.g.) the Mail addresses should be shown and the user should select one.
• After selection of a Mail address just the (e.g.) phone numbers should be shown and the user should select one.

The solution until the third aspect is well-known:

- (IBAction)importFromAddressBook 
{
    ABPeoplePickerNavigationController* picker = [[ABPeoplePickerNavigationController alloc] init];
    picker.peoplePickerDelegate = self;
    [self presentModalViewController:picker animated:YES];
    [picker release];
}

- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker 
{
    [self dismissModalViewControllerAnimated:YES];
}

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker 
      shouldContinueAfterSelectingPerson:(ABRecordRef)person 
{
    [peoplePicker setDisplayedProperties:[NSArray arrayWithObject:[NSNumber numberWithInt:kABPersonEmailProperty]]];
    return YES;
}

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker
      shouldContinueAfterSelectingPerson:(ABRecordRef)person
                                property:(ABPropertyID)property
                              identifier:(ABMultiValueIdentifier)identifier 
{
    //===PROBLEM=== Now I do have a mail address and I want to have a phone number right afterwards.

    //Something like this would be straightforward, but the view does not change this way:
    [peoplePicker setDisplayedProperties:[NSArray arrayWithObject:[NSNumber numberWithInt:kABPersonPhoneProperty]]];
    //Here misses the important code.


    //And only when I also got a phone number through this or a similar method I want to call:
    [peoplePicker dismissModalViewControllerAnimated:YES];

    //I do not want to start default behaviour with the mailaddress and/or phone number:
    return NO;
}

The right approach seems to push a similar peoplePicker View on the NavigationController of the ModalView, but I don't know how.

If anyone had any idea it would be great!

If you want to see such a behavior in action you can have a look at the Amazon app: If you go through the first steps of an order you can select a shipping address exactly this way: From Contact List -> Select a Person -> Select an Address -> Select a Telephone number. There, everything (seems to) take place in the modal view with just a navigation hierarchy with one more level than in the standard code shown above.

I guess this might be what you want:

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker
      shouldContinueAfterSelectingPerson:(ABRecordRef)person 
                                property:(ABPropertyID)property
                              identifier:(ABMultiValueIdentifier)identifier 
{

    ABPersonViewController *controller = [[ABPersonViewController alloc] init];
    controller.displayedPerson = person;
    controller.displayedProperties = [NSArray arrayWithObject:[NSNumber numberWithInt:kABPersonPhoneProperty]];
    controller.personViewDelegate = self;
    [peoplePicker pushViewController:controller animated:YES];
    [controller release];
    return NO;
}

- (BOOL)personViewController:(ABPersonViewController *)personViewController 
shouldPerformDefaultActionForPerson:(ABRecordRef)person 
                    property:(ABPropertyID)property
                  identifier:(ABMultiValueIdentifier)identifierForValue
{
    ABMutableMultiValueRef multi = ABRecordCopyValue(person, property);
    CFStringRef phone = ABMultiValueCopyValueAtIndex(multi, identifierForValue);
    NSLog(@"phone %@", (NSString *)phone);
    CFRelease(phone);

    ABPeoplePickerNavigationController *peoplePicker = (ABPeoplePickerNavigationController *)personViewController.navigationController;
    [peoplePicker dismissModalViewControllerAnimated:YES];
    return NO;
}

The idea is, to create another ABPersonViewController instance, and let your people picker to push it, since ABPeoplePickerNavigationController is a subclass of NSPeoplePickerNavigationController.
