ABAddressBook获取生日属性

Question

我正在尝试从我的iphone上的ABAddressBook获取生日属性。我在网上浏览了一些讨论，大多推荐相同的答案，我自己也试过了，如下所示。但这对我来说仍然不起作用，所以我想知道我是否遗漏了其他东西……

        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);

任何帮助都非常感谢..谢谢。

Answer 1

这对我来说很有效：

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

Answer 2

试试这个：

 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);
  }
