Answer 1

From IOS 6. it need to authorize your apps for to access system datas : In settings on your IPhone in confidentiality tab and contact section, verify if your app has acces is "on"

Answer 2

To continue TDelepine's suggestion, perhaps in your getPersonOutOfAddressBook method, you can check if your app has AddressBook access. The code below will force the device to ask the user for access if access status has not been determined:

 ...
NSLog(@"Succesful.");

if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
    ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {

       if(granted) {
            NSArray *allContacts = (__bridge_transfer NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);
            etc...
        }
    });
}

I think you're not sending request for access Address Book. One other thing If you're not using this then It's work properly in simulator but not working in iPhone

Use this code in ViewDidLoad

ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL);
__block BOOL accessGranted = NO;
if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6
    dispatch_semaphore_t sema = dispatch_semaphore_create(0);
    ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {
        accessGranted = granted;
        dispatch_semaphore_signal(sema);
    });
    dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
    //  dispatch_release(sema); 
}
else { // we're on iOS 5 or older
    accessGranted = YES;
}

if (accessGranted) {
    // Do whatever you want here.
}
