copied!<p>As per <a href="https://developer.apple.com/library/ios/documentation/Contacts/Reference/Contacts_Framework/" rel="noreferrer">this documentation</a> on apple's site (scroll down to Privacy in the middle of the page), access to the address book <strong>must be granted</strong> before it can be access programmatically. Here is what I ended up doing.</p> <pre><code> #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 } </code></pre> <p><strong>Update For iOS 9 and later:</strong></p> <p>From Apple website :</p> <blockquote> <p>Important</p> <p>The Address Book UI framework is deprecated in iOS 9. Use the APIs defined in the ContactsUI framework instead. To learn more, see <a href="https://developer.apple.com/reference/contactsui" rel="noreferrer">ContactsUI</a></p> </blockquote>
