iOS 8에서 ABPeoplePickerNavigationController의 변경점

	// iOS 8에서는 iOS 7 까지 쓰이던 아래의 델리게이트 메소드가 호출이 안되고 새로운 메소드와 프로퍼티가 추가됨
	- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person
	- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
	//iOS 8에서 추가된 델리게이트 메소드
	- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
	- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person
	//iOS 8에서 추가된 델리게이트 프로퍼티
	@property(nonatomic,copy) NSPredicate *predicateForEnablingPerson
	@property(nonatomic,copy) NSPredicate *predicateForSelectionOfPerson
	@property(nonatomic,copy) NSPredicate *predicateForSelectionOfProperty
	//변경에 대응하는 법
	//1. iOS 7 델리게이트 메소드를 부르도록 추가
	- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
	{
	[self peoplePickerNavigationController:peoplePicker shouldContinueAfterSelectingPerson:person property:property identifier:identifier];
	}
	- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person
	{
	[self peoplePickerNavigationController:peoplePicker shouldContinueAfterSelectingPerson:person];
	}
	//2. 기존 shouldContinueAfterSelectingPerson 메소드에서는 리턴값으로 데이터 처리방법을 선택했으나
	//iOS 8에서는 추가된 프로퍼티들에 적절한 NSPredicate를 설정하여 제어.
	peoplePicker.predicateForSelectionOfPerson = [NSPredicate predicateWithFormat:@"%K.@count <= 1", ABPersonPhoneNumbersProperty];
	peoplePicker.predicateForSelectionOfPerson = [NSPredicate predicateWithFormat:@"%K.@count <= 1", ABPersonEmailAddressesProperty];
