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 

<pre><code>ABAddressBookRef addressBook = ABAddressBookCreate();
</code></pre>

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.

<pre><code>__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.
}
</code></pre>

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.

According to iOS recent apple development documentation, apple insists to use <a href="https://developer.apple.com/documentation/contacts?language=objc" rel="nofollow noreferrer">Contact</a> besides <a href="https://developer.apple.com/documentation/addressbook?language=objc" rel="nofollow noreferrer">AddressBook</a>. 

<pre><code>CNAuthorizationStatus authorizationStatus = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
 switch (authorizationStatus) {
 case CNAuthorizationStatusNotDetermined: {

 break;

 case CNAuthorizationStatusRestricted: {

Above objective c code helps to find weather contact access permission is granted or not.

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 <a href="http://www.cultofmac.com/179733/19-of-ios-apps-access-your-address-book-without-your-permission-until-ios-6-report/" rel="noreferrer">this</a> 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 <code>ABAddressBookErrorDomain error 1</code>. 

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

自从更新到iPhone6之后，我注意到我将联系人添加到iOS地址簿的代码不再起作用。我认为这是一个与权限相关的问题，因为苹果现在需要用户权限才能访问联系人(修复问题)。我本以为这个应用会自动请求访问联系人的权限，就像下面的截图一样，但它没有。尝试添加联系人时出现ABAddressBookErrorDomain erro...
