iOS 6 Address Book not working?

Question

My method of programmatically retrieving e-mail addresses from the Address Book no longer seems to work on iOS 6 devices. It worked in iOS 5 and oddly, still works in the iO

Answer 1

Probably related to the new privacy controls, as of iOS 6, on the device, an app can’t access the user’s contacts without their permission.

Code:

-(void)addressBookValidation
{



NSUserDefaults *prefs=[NSUserDefaults standardUserDefaults];
ABAddressBookRef addressbook = ABAddressBookCreate();
__block BOOL accessGranted = NO;

if (ABAddressBookRequestAccessWithCompletion != NULL)
{
    if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined)
    {
        dispatch_semaphore_t sema = dispatch_semaphore_create(0);
        ABAddressBookRequestAccessWithCompletion(addressbook, ^(bool granted, CFErrorRef error)
                                                 {
                                                     accessGranted = granted;
                                                     dispatch_semaphore_signal(sema);
                                                 });
        dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
        dispatch_release(sema);
    }
    else if(ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized)
    {
        accessGranted = YES;
    }
    else if (ABAddressBookGetAuthorizationStatus()==kABAuthorizationStatusDenied)
    {
        accessGranted = NO;
    }
    else if (ABAddressBookGetAuthorizationStatus()==kABAuthorizationStatusRestricted){
        accessGranted = NO;
    }
    else
    {
        accessGranted = YES;
    }


}
else
{
    accessGranted = YES;
}
[prefs setBool:accessGranted forKey:@"addressBook"];

NSLog(@"[prefs boolForKey:@'addressBook']--->%d",[prefs boolForKey:@"addressBook"]);
[prefs synchronize];
CFRelease(addressbook);
}
