IOS 8 - ABPeoplePickerNavigationController - Cancel delegate method works, others do not

Question

I've encountered a strange problem in my IOS 8 people picker delegate code. Only the

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

method is being called. I have reviewed other questions and have made the important IOS 8 delegate method changes for selecting a contact by calling the old IOS 7 method

- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:   (ABMultiValueIdentifier)identifier {
    [self peoplePickerNavigationController:peoplePicker shouldContinueAfterSelectingPerson:person property:property identifier:identifier];
}

but it is never called.

I am setting the delegate in the calling viewcontroller didLoad,

and it works perfectly in ios 7. This is a storyboard application.

I saw the same question asked in a comment here: ABPeoplePickerNavigationController changes with iOS8?

but never found an answer. Obviously a mistake somewhere on my part, but I can't find it.

UPDATE: As requested, here is how I set the delegate:

self.picker = [[ABPeoplePickerNavigationController alloc] init];
self.picker.peoplePickerDelegate = self;

And, in @interface:

@interface TreatmentsAddEntryTVC :    UITableViewController<UITextViewDelegate,ABPeoplePickerNavigationControllerDelegate>

Answer 1

Try using this delegate method instead and see if it hits:

- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person;
{
   // yes the below line is deprecated as of iOS 8
   [self peoplePickerNavigationController:peoplePicker shouldContinueAfterSelectingPerson:person];
}

Answer 2

I hate to answer my own question, especially when the answer makes no sense, but moving:

self.picker = [[ABPeoplePickerNavigationController alloc] init];
self.picker.peoplePickerDelegate = self;

from didLoad to the method where I actually want to display the picker fixed the problem. I have seen at least one other question on SO where this behavior was noted and discussed:

Cannot select contact on iOS 8

Answer 3

For a project with iOS 8.1, I replaced this method

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

with this

-(void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person{
}

And new method did hit when I selected a contact.
