我正在尝试获取组名称，但经过多次“由用户重新加载联系人”调用此方法后，它会给出nil值和以下错误。

-(void) getGroupsName
    {
        [groupsName removeAllObjects];
        //address book object to interact with iPhone contacts.
        ABAddressBookRef addressbook = ABAddressBookCreate();
        //get groups count
        CFIndex groupsCount          = ABAddressBookGetGroupCount(addressbook);
        //get all available groups as array
        CFArrayRef allGroups         = ABAddressBookCopyArrayOfAllGroups(addressbook);

        for (int i = 0; i<groupsCount; i++) {
            //get group of index=i from groups array
            ABRecordRef group = CFArrayGetValueAtIndex(allGroups, i);
            //get group name, I use __bridge_transfer to transfer from C to objective-c.
            [groupsName addObject:(__bridge_transfer NSString*)ABRecordCopyCompositeName(group)];

        }
        CFRelease(allGroups);
        CFRelease(addressbook);
    }

所以我使用本机通知让我知道什么时候addressbook被修改以减少我访问的次数addressbook，但如果用户进行多次更新并且每次addrssbook修改必须调用这个肉类或任何其他相关的addressbook.

所以还需要你的帮助？？？

ABAddressBookCreate已在 iOS6 中弃用。使用，如果您无权访问通讯录ABAddressBookCreateWithOptions，它将返回一个对象。CFErrorRef

您为什么不尝试ABAddressBookRef使用以下方法尽量减少创建和访问的时间：

void ABAddressBookRegisterExternalChangeCallback (
   ABAddressBookRef addressBook,
   ABExternalChangeCallback callback,
   void *context
);

这允许您的应用程序知道地址簿何时被外部修改。并让您知道您需要重新访问地址簿。

您发布的方法与您发布的方法相同，每次调用它都会创建具有新访问地址簿的新对象

正如@thelaws 所指出的，您必须在IOS6 中使用ABAddressBookCreateWithOptions。if ([[[UIDevice currentDevice] systemVersion] floatValue] > 5.1) {

   ABAddressBookRef ab = ABAddressBookCreateWithOptions(NULL, NULL);
    __block BOOL accessGranted = NO;
    if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
        ABAddressBookRequestAccessWithCompletion(ab, ^(bool granted, CFErrorRef error) {
            // First time access has been granted, add the contact
            accessGranted = granted;
        });
    }
    else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized)        {
        // The user has previously given access, add the contact
        accessGranted = YES;
    }
    else {
        // The user has previously denied access
        // Send an alert telling user to change privacy setting in settings app
    }
    if (accessGranted) {
// your code goes here
 }
}
else {
// your code goes here
}

另一件事是您是否已在某处初始化了 groupsName ？

除此之外，您是否使用 ABExternalChangeCallBack 来获取地址簿更改的通知？

我认为您应该将组代码放在访问联系人的同一模块中。（如果这对您没有帮助，请澄清！）
