Question

What I’m trying to do is show the people picker to the user, make him select all the contacts he wants, and finally get all those contacts’ email addresses in an array.
The best would be showing only contacts with email to the user.

Until now the only thing I’ve been able to do is presenting the people picker with this code:

ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
     picker.peoplePickerDelegate = self;
     [self presentModalViewController:picker animated:YES];

Then I was trying to use this code to get the selected contacts’ email:

- (BOOL)peoplePickerNavigationController: (ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person {

ABMultiValueRef multi = ABRecordCopyValue(person, kABPersonEmailProperty);
[email addObject:(__bridge NSString*)ABMultiValueCopyValueAtIndex(multi, 0)];
[self dismissModalViewControllerAnimated:YES];

return YES;
}

But the picker is going away as soon as I select a contact, so I don’t know how to continue.
Moreover, right when I select a contact I get this in the console:

"Unbalanced calls to begin/end appearance transitions for 
<ABMembersViewController: 0xa1618c0>."

Any help would be appreciated.

I am not sure if you ever solved your problem but if anyone else finds this post maybe it will help them.
What I did to get an email from the ABPeoplePickerNavigationController was to remove

[self dismissModalViewControllerAnimated:YES];

from

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person;

and then I am using this to get the email and dismiss the controller

- (BOOL)peoplePickerNavigationController(ABPeoplePickerNavigationController*)peoplePicker
  shouldContinueAfterSelectingPerson:(ABRecordRef)person
                            property:(ABPropertyID)property
                          identifier:(ABMultiValueIdentifier)identifier
{
    if (kABPersonEmailProperty == property)
    {
        ABMultiValueRef multi = ABRecordCopyValue(person, kABPersonEmailProperty);
        NSString *email = (__bridge NSString *)ABMultiValueCopyValueAtIndex(multi, 0);
        NSLog(@"email: %@", email);
        [self dismissModalViewControllerAnimated:YES];
        return NO;
    }
    return YES;
}

It allows the user to select a specific email and dismisses the controller without any errors.
