contact - peoplePickerNavigationController didSelectPerson 未调用链接联系人

Question

当用户使用 ABPeoplePickerNavigationController 点击链接联系人的属性时 - 既不 - (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier 也不 (BOOL) peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier被调用。对于定期联系，这很有效。我究竟做错了什么？

这是我显示联系人的方式：

ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
    NSArray *displayedItems = [NSArray arrayWithObjects:[NSNumber numberWithInt:kABPersonPhoneProperty],
                               [NSNumber numberWithInt:kABPersonEmailProperty], nil];


    picker.displayedProperties = displayedItems;
    picker.peoplePickerDelegate = self;
    [self presentViewController:picker animated:YES completion:nil];
