iOS 6 地址簿不起作用？

iOS 6 Address Book not working?

提问by Keller

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 iOS 6 Simulator. Is there a new way to programmatically retrieve contacts from a users' Address Book?

我从通讯簿中以编程方式检索电子邮件地址的方法似乎不再适用于 iOS 6 设备。它在 iOS 5 中工作，奇怪的是，在 iOS 6 模拟器中仍然有效。有没有一种以编程方式从用户的通讯簿中检索联系人的新方法？

ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);

self.contacts = [[NSMutableArray alloc] init];

int contactIndex = 0;
for (int i = 0; i < nPeople; i++) {
    // Get the next address book record.
    ABRecordRef record = CFArrayGetValueAtIndex(allPeople, i);        

    // Get array of email addresses from address book record.
    ABMultiValueRef emailMultiValue = ABRecordCopyValue(record, kABPersonEmailProperty);
    NSArray *emailArray = (__bridge_transfer NSArray *)ABMultiValueCopyArrayOfAllValues(emailMultiValue);

    [self.contacts addObject:emailArray];
}

To clarify, the above does not crash, it simply returns no results. ABAddressBookCopyArrayOfAllPeople is empty. Thanks!

澄清一下，上面没有崩溃，它只是不返回任何结果。ABAddressBookCopyArrayOfAllPeople 为空。谢谢！

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. From the documentation:

可能与新的隐私控制有关——从 iOS 6 开始，在设备上，未经用户许可，应用程序无法访问用户的联系人。从文档：

On iOS 6.0 and later, if the caller does not have access to the Address Book database:

? For apps linked against iOS 6.0 and later, this function returns NULL.

? For apps linked against previous version of iOS, this function returns an empty read-only database.

在 iOS 6.0 及更高版本上，如果呼叫者无权访问地址簿数据库：

? 对于链接到 iOS 6.0 及更高版本的应用程序，此函数返回 NULL。

? 对于与以前版本的 iOS 链接的应用程序，此函数返回一个空的只读数据库。

If you haven't seen the permissions alert come up (“SomeApp would like access to your contacts”), it's possible that the direct address-book APIs just assume that they don't have access and silently fail; you might have to display something from the AddressBookUI framework to trigger it.

如果您还没有看到权限警报出现（“SomeApp 想要访问您的联系人”），则可能是直接地址簿 API 只是假设它们没有访问权限并默默地失败；您可能需要显示 AddressBookUI 框架中的某些内容才能触发它。

I created a helper class, AddressBookHelper, to handle backward compatibility. Here are the guts:

我创建了一个辅助类AddressBookHelper，来处理向后兼容性。以下是胆量：

-(BOOL)isABAddressBookCreateWithOptionsAvailable {
    return &ABAddressBookCreateWithOptions != NULL;
}

-(void)loadContacts {
    ABAddressBookRef addressBook;
    if ([self isABAddressBookCreateWithOptionsAvailable]) {
        CFErrorRef error = nil;
        addressBook = ABAddressBookCreateWithOptions(NULL,&error);
        ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
            // callback can occur in background, address book must be accessed on thread it was created on
            dispatch_async(dispatch_get_main_queue(), ^{
                if (error) {
                    [self.delegate addressBookHelperError:self];
                } else if (!granted) {
                    [self.delegate addressBookHelperDeniedAcess:self];
                } else {
                    // access granted
                    AddressBookUpdated(addressBook, nil, self);
                    CFRelease(addressBook);
                }
            });
        });
    } else {
        // iOS 4/5
        addressBook = ABAddressBookCreate();
        AddressBookUpdated(addressBook, NULL, self);
        CFRelease(addressBook);
    }
}

void AddressBookUpdated(ABAddressBookRef addressBook, CFDictionaryRef info, void *context) {
    AddressBookHelper *helper = (AddressBookHelper *)context;
    ABAddressBookRevert(addressBook);
    CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(addressBook);

    // process the contacts to return
    NSArray *contacts = ...    

    [[helper delegate] addressBookHelper:helper finishedLoading:contacts];
};

Try with this: access to the address book must be grantedbefore it can be access programmatically. Here is what I ended up doing.

试试这个：必须先授予对地址簿的访问权限，然后才能以编程方式访问它。这是我最终做的。

  #import <AddressBookUI/AddressBookUI.h>

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

  if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
    ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {
      // First time access has been granted, add the contact
      [self _addContactToAddressBook];
    });
  }
  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
  }
