Unable to fetch mobile numbers from Contact List. iOS6 - iphone

Question

I am new to iphone App Development(using iOS6) and have been facing problem with fetching the mobile Numbers from the contact List into a UITableViewController. I can get the first name and last name correctly but the phone Numbers are being returned as null. I could not understand the reason behind this.What is it that I am doing wrong? My code is as follows:
NSMutableArray *people = (__bridge_transfer NSMutableArray *) ABAddressBookCopyArrayOfAllPeople (addressBookRef);
NSString *firstName = (__bridge_transfer NSString *)ABRecordCopyValue((__bridge ABRecordRef)([people objectAtIndex:indexPath.row]), kABPersonFirstNameProperty);
NSString *lastName = (__bridge_transfer NSString *)ABRecordCopyValue((__bridge ABRecordRef)([people objectAtIndex:indexPath.row]), kABPersonLastNameProperty);
ABMultiValueRef phoneNumbers = ABRecordCopyValue((__bridge ABRecordRef)([people objectAtIndex:indexPath.row]),kABPersonPhoneProperty);
if (([firstName isEqualToString:#""] || [firstName isEqualToString:#"(null)"] || firstName == nil) &&
([lastName isEqualToString:#""] || [lastName isEqualToString:#"(null)"] || lastName == nil))
{
// do nothing
}
else
{
aName = [NSString stringWithFormat:#"%# %#", firstName, lastName];
if ([firstName isEqualToString:#""] || [firstName isEqualToString:#"(null)"] || firstName == nil)
{
aName = [NSString stringWithFormat:#"%#", lastName];
}
if ([lastName isEqualToString:#""] || [lastName isEqualToString:#"(null)"] || lastName == nil)
{
aName = [NSString stringWithFormat:#"%#", firstName];
}
//[self.tableItems addObject:aName];
NSLog(#"%# added",aName);
}
//fetch multiple phone nos. and use only 0th
id person = people[indexPath.row];
ABMultiValueRef multi = ABRecordCopyValue((__bridge ABRecordRef)(person), kABPersonPhoneProperty);
NSString* phone = (__bridge NSString*)ABMultiValueCopyValueAtIndex(multi, 0);
NSLog(#"%#",phone);
[cell.detailTextLabel setText:phone];
[cell.textLabel setText:aName];
return cell;

Here this is a full working code
-(void)GetAddressBook
{
Contacts = [[NSMutableArray alloc]init];
if (ABAddressBookCreateWithOptions) {
#try {
ABAddressBookRef addressBook = ABAddressBookCreate();
// NSArray *people = (NSArray*)ABAddressBookCopyArrayOfAllPeople(addressBook);
if (!addressBook) {
NSLog(#"opening address book");
}
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);
NSLog(#"opening address book ==%ld",nPeople);
for (int i=0;i < nPeople;i++) {
NSMutableDictionary *dOfPerson=[NSMutableDictionary dictionary];
ABRecordRef ref = CFArrayGetValueAtIndex(allPeople,i);
NSString *Contact;
ABMultiValueRef phones =(__bridge ABMultiValueRef)((__bridge NSString*)ABRecordCopyValue(ref, kABPersonPhoneProperty));
CFStringRef firstName, lastName;
NSMutableArray *array = [[NSMutableArray alloc]init];
NSString *email;
firstName = ABRecordCopyValue(ref, kABPersonFirstNameProperty);
lastName = ABRecordCopyValue(ref, kABPersonLastNameProperty);
ABMultiValueRef multiValueRef = ABRecordCopyValue(ref, kABPersonEmailProperty);
array = [(__bridge NSMutableArray *)ABMultiValueCopyArrayOfAllValues(multiValueRef) mutableCopy];
email = ([array count] > 0) ? array[0] : #"";
if(firstName)
{
Contact = [NSString stringWithFormat:#"%#", firstName];
if(lastName)
Contact = [NSString stringWithFormat:#"%# %#",firstName,lastName];
}
[dOfPerson setObject:Contact forKey:#"name"];
[dOfPerson setObject:[NSString stringWithFormat:#"%d", i] forKey:#"id"];
[dOfPerson setObject:[NSString stringWithFormat:#"%#",#""] forKey:#"found"];
[dOfPerson setObject:email forKey:#"email"];
NSString* mobileLabel;
for(CFIndex j = 0; j< ABMultiValueGetCount(phones); j++)
{
mobileLabel = (__bridge NSString*)ABMultiValueCopyLabelAtIndex(phones, j);
if([mobileLabel isEqualToString:(NSString *)kABPersonPhoneMobileLabel])
{
[dOfPerson setObject:(__bridge NSString*)ABMultiValueCopyValueAtIndex(phones, j) forKey:#"Phone"];
}
else if ([mobileLabel isEqualToString:(NSString*)kABPersonPhoneIPhoneLabel])
{
[dOfPerson setObject:(__bridge NSString*)ABMultiValueCopyValueAtIndex(phones, j) forKey:#"Phone"];
break ;
}
}
[Contacts addObject:dOfPerson];
}
}
#catch (NSException * e) {
NSLog(#"Exception: %#", e);
}
dispatch_async(dispatch_get_main_queue(), ^{
});
}
The Phone numbers are to be taken like ABMultiValueRef phones =(__bridge ABMultiValueRef)((__bridge NSString*)ABRecordCopyValue(ref, kABPersonPhoneProperty));
