how to pick the birthday labels from the contacts in Addressbook? - ios

Question

I working with the Addressbook for fetch the contacts list with their labels. (like mobile, main, home, work, fax..etc). I fetched the phone, email labels from the contacts but i did not fetch the birthday, anniversary labels. Here is my code for birthday class.
ABMultiValueRef dateofbirth1 = ABRecordCopyValue(contactPerson, kABPersonBirthdayProperty); // Assign the Date Of birth
NSString *dob1=[NSDateFormatter localizedStringFromDate:(__bridge NSDate *)(dateofbirth1) dateStyle:NSDateFormatterLongStyle timeStyle:0]; // Changing to string format using Date Formatter.
if(!(dob1==nil))
{
// DOB is Not Nill
}
Here is my fetch the BirthDay Label Code
if([arrayOfDatesAsStrings count]>0)
{
for (int j = 0; j < [arrayOfDatesAsStrings count] ; j++)
{
**//This is the fetching birthday label code and following code is crashed**
CFStringRef locLabel1 = ABMultiValueCopyLabelAtIndex((__bridge ABMultiValueRef)(dob1), j);
NSString *phoneLabel1 =(__bridge NSString*) ABAddressBookCopyLocalizedLabel(locLabel1);
personD.dateOfBirth = phone1;
NSLog(#" %# %#",phoneLabel1,personD.dateOfBirth);
}
}
else
{
NSLog(#"Date Of Birth was Not set ");
}
What can i do for this? can Any one help me? The Crash Error Message is :
"Thread 1:Exc_BAD_ACCESS (Code=1, address=0x38)"

To fetch contacts from devices
if (isIOS9) { //checking iOS version of Device
CNContactStore *store = [[CNContactStore alloc] init];
//keys with fetching properties
NSArray *keys = #[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactEmailAddressesKey,CNContactPostalAddressesKey, CNLabelWork, CNLabelDateAnniversary];
NSString *containerId = store.defaultContainerIdentifier;
NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
NSError *error;
NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
DLOG(#"cnContacts %lu",(unsigned long)cnContacts.count);
if (error) {
//error
} else {
for (CNContact *contact in cnContacts) {
//iterate over cnContacts to get details
}
}
} else {
//for below iOS 9
ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef arrPersons = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFIndex count = ABAddressBookGetPersonCount(addressBook);
NSLog(#"cnContacts %lu",(unsigned long)count);
for (int i = 0; i < count; i++) {
ABRecordRef record = CFArrayGetValueAtIndex(arrPersons,i);
//use kABPersonBirthdayProperty to get b’day
NSString *birthDay = (__bridge NSString *)(ABRecordCopyValue(record, kABPersonBirthdayProperty));
NSLog(#“B’day %#”, birthDay);
}
}
