ABAddressBook get birthday property

问题

I'm trying to get the birthday property from ABAddressBook on my iphone. I've looked through some discussions over the web and mostly recommends the same answer, which I have tried myself as below. But this still doesn't work for me so I wonder if i missed something else....

        dayFormatter = [[[NSDateFormatter alloc] init]autorelease];
    [self.dayFormatter setDateFormat:@"MMMM d"];        

    NSString* today = [dayFormatter stringFromDate:[NSDate date]];
    NSLog(@"today:%@", today);
    NSLog(@"date:%@", [NSDate date]); // this works fine


    NSDate *bday = (NSDate*)ABRecordCopyValue(personRecord,kABPersonBirthdayProperty);
    NSLog(@"bdayyyy:%@", bday); // this doesn't work.


    NSString* personBday = [dayFormatter stringFromDate:bday];
    NSLog(@"Bday:%@", personBday);

any help is much appreciated.. Thanks.

This works for me:

NSDate* birthDate = (__bridge_transfer NSDate*)ABRecordCopyValue(addressBookContact, kABPersonBirthdayProperty);

Try this:

 ABAddressBookRef myAddressBook = ABAddressBookCreate();
 NSArray *allPeople = (NSArray *)ABAddressBookCopyArrayOfAllPeople(myAddressBook);

 for (id record in allPeople) {
     NSMutableDictionary *newRecord = [[NSMutableDictionary alloc] init];
     CFTypeRef bDayProperty = ABRecordCopyValue((ABRecordRef)record, kABPersonBirthdayProperty);

     if (ABRecordCopyValue((ABRecordRef)record, kABPersonBirthdayProperty)) 
       {
         NSDate *date=(NSDate*)bDayProperty;
         [newRecord setObject:date forKey:@"birthDate"];
         date=nil;
         [date release]; 
     }
    CFRelease(myAddressBook);
  }
