peoplePicker memory leak using ARC

[smithms]

I am using ARC in my project and am being warned of a potential memory leak (see commented lines) on the following. Not sure how to handle it.

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

ABMultiValueRef phoneProperty = ABRecordCopyValue(person,property);
  // Call to function 'ABRecordCopyValue' returns a Core Foundation object with a +1 retain count
	
int idx = ABMultiValueGetIndexForIdentifier (phoneProperty, identifier);	
	
emailToValue= (__bridge_transfer NSString *)ABMultiValueCopyValueAtIndex(phoneProperty,idx);
  // Object Leaked: object allocated and stored into 'phoneProperty' is not referenced later in this execution path and has a retain count of +1

Any advice would be appreciated.

Thanks in advance
