iPhone-Get All contacts from iPhone AddressBook

 Steps:

1.  Add Observer to Handle Changes in Contact Book

2. Asking For Permission to grant access to use Iphone AddressBook

3. If Granted then Read Address Book and store

 

//Observer to handle changes in Contact Boo

- (void)viewDidLoad
{
    [super viewDidLoad];

 ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(nil, nil);
    ABAddressBookRegisterExternalChangeCallback(addressBook, addressBookChanged, (__bridge void *)(self));

}

// Address Book Authorization grant place this code in viewDidAppear

-(void)viewDidAppear:(BOOL)animated
{

    if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusDenied ||
        ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusRestricted)
    {
        NSLog(@"AB Denied");
    }
    else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized)
    {
        NSLog(@"AB Authorized");
      
            [self address_book];
    }
    else
    {
        ABAddressBookRequestAccessWithCompletion(ABAddressBookCreateWithOptions(NULL, nil), ^(bool granted, CFErrorRef error)
                                                 {
                                                     if (!granted) {
                                                        NSLog(@"AB Just denied");
                                                         return;
                                                     }

                                                     NSLog(@"AB Just authorized");
                                                 });
