Programmatically Request Access to Contacts

Since updating to iOS 6 I've noticed that my code to add a contact to iPhone's address book no longer works. I believe this is a permission related problem, since Apple now requires user permission before accessing contacts (fixing this issue).

I expected the app to automatically ask permission to access contacts, like in the screenshot below, but it doesn't. Trying to add the contact just fails with ABAddressBookErrorDomain error 1.

Do I need to programmatically launch the access to contacts request dialog? How is that done?

As per this documentation on apple's site (scroll down to Privacy in the middle of the page), access to the address book must be granted before it can be access programmatically. Here is what I ended up doing.

  #import <AddressBookUI/AddressBookUI.h>

  // Request authorization to Address Book
  ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL);

  if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
    ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {
      if (granted) {
          // First time access has been granted, add the contact
          [self _addContactToAddressBook];
      } else {
          // User denied access
          // Display an alert telling user the contact could not be added
      }
    });
  }
  else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
    // The user has previously given access, add the contact
    [self _addContactToAddressBook];
  }
  else {
    // The user has previously denied access
    // Send an alert telling user to change privacy setting in settings app
  }

Update For iOS 9 and later:

From Apple website :

> Important > >The Address Book UI framework is deprecated in iOS 9. Use the APIs defined in the ContactsUI framework instead. To learn more, see ContactsUI

That did the perfect trick for me!

On iOS6, apple introduce new privacy control, user can control the accessment of contact and calender by each app. So, in the code side, you need to add some way to request the permission. In iOS5 or before, we can always call

ABAddressBookRef addressBook = ABAddressBookCreate();

to get the addressbook without any problem, but in iOS6, if you don't have permission, this call will just return empty pointer. That why we need to change the method to get ABAddressBookRef.

__block BOOL accessGranted = NO;
if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6
    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 { // we're on iOS 5 or older
    accessGranted = YES;
}

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

In the code,semaphore is used for blocking until response, while ABAddressBookRequestAccessWithCompletion will ask for permission if the app didn't ask before. Otherwise it will just follow the settings in Settings-Privacy-Contact.

Had some problems with yunas code on iOS6.1 in Xcode5. With some small adaptions it worked for me.

The problem was that ARC in iOS 6, did not allows dispatch_release(sema); Here's the working code. Note: I use m_addressbook instead of addressbook as ABAddressBookRef!

#import <AddressBook/AddressBook.h>

      dispatch_semaphore_t sema = dispatch_semaphore_create(0);
      dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

According to iOS recent apple development documentation, apple insists to use [Contact][1] besides [AddressBook][2].

CNAuthorizationStatus authorizationStatus = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
    switch (authorizationStatus) {
        case CNAuthorizationStatusNotDetermined: {
            
            break;
        }
        case CNAuthorizationStatusRestricted: {
            
            break;
        }
        case CNAuthorizationStatusDenied:{
            
            return;
        }
            break;
        case CNAuthorizationStatusAuthorized: {
            
            break;
        }
    }

Above objective c code helps to find weather contact access permission is granted or not. [1]: https://developer.apple.com/documentation/contacts?language=objc [2]: https://developer.apple.com/documentation/addressbook?language=objc

If anyone have problem with addressBook in iOS5 then Use

ABAddressBookRef addressBook = ABAddressBookCreate(); 

Insted of

ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL,NULL);

ABAddressBookRequestAccessWithCompletion(ABAddressBookCreateWithOptions(NULL, nil), ^(bool granted, CFErrorRef error) {
        dispatch_async(dispatch_get_main_queue(), ^{
            if (!granted){
                    [[[UIAlertView alloc] initWithTitle:@"Contacts Access Denied"
                                                message:@"This app requires access to your device's Contacts.\n\nPlease enable Contacts access for this app in Settings / Privacy / Contacts"
                                               delegate:nil
                                      cancelButtonTitle:@"Dismiss"
                                      otherButtonTitles:nil] show];
            } else {
                //access authorized
            }
        });
    });

For add description to alert use in InfoPlist.strings.

NSContactsUsageDescription = "TESTING!";

Swift 3. Don't forget to import Contacts

func requestForContactAccess(completionHandler: @escaping (_ accessGranted: Bool) -> Void) {
    let authorizationStatus = CNContactStore.authorizationStatus(for: CNEntityType.contacts)
    switch authorizationStatus {
    case .authorized:
        completionHandler(true)
    case .denied, .notDetermined:
        self.contactStore.requestAccess(for: CNEntityType.contacts, completionHandler: { (access, accessError) -> Void in
            if access {
                completionHandler(access)
            } else {
                if authorizationStatus == CNAuthorizationStatus.denied {
                    DispatchQueue.main.async(execute: { () -> Void in
                        let message = "\(accessError!.localizedDescription)\n\nPlease allow the app to access your contacts through the Settings."
                        self.showMessage(message: message)
                    })
                }
            }
        })
    default:
        completionHandler(false)
    }
}

With iOS 6 you have to ask permission like this
