ios - ABGroupCreate 不适用于 Exchange

Question

当我在模拟器上运行这段代码时遇到了问题，我得到了组的 ID，但是当我在设备上运行它时，ID 设置为 -1 ... 但错误消息保持为空。

    -(NSNumber *)addGroupeToAddressbookWithName:(NSString *)name{
    ABAddressBookRef addressBook = ABAddressBookCreate();
    CFErrorRef error = NULL;
    ABRecordRef group = ABGroupCreate();
    ABRecordSetValue(group, kABGroupNameProperty,(__bridge CFStringRef)name, &error);
    ABAddressBookAddRecord(addressBook, group, &error);
    ABAddressBookSave(addressBook,&error);
    NSNumber *gId = [NSNumber numberWithInt:ABRecordGetRecordID(group)];

    CFRelease(group);
    return gId;
}

我不知道有什么区别，也不知道如何让它在真实设备上运行。

编辑:发现如果我删除手机上的 exchange sync 就可以工作，但仍然希望它在能够在手机上拥有 exchange 帐户的同时工作。所以并没有真正解决问题

发现是因为exchange不知道组，要保存一个组需要使用正确的源，另见:Obtaining Specific ABSource from ABAddressBook in iOS 4+

新代码:

-(NSNumber *)addGroupeToAddressbookWithName:(NSString *)name{
    ABAddressBookRef addressBook = ABAddressBookCreate();
    CFErrorRef error = NULL;
    CFArrayRef sources = ABAddressBookCopyArrayOfAllSources(addressBook);
    CFIndex sourceCount = CFArrayGetCount(sources);
    NSNumber *gId = nil;
    for (CFIndex i = 0 ; i < sourceCount; i++) {
        ABRecordRef currentSource = CFArrayGetValueAtIndex(sources, i);
        CFTypeRef sourceType = ABRecordCopyValue(currentSource, kABSourceTypeProperty);

        BOOL isMatch = kABSourceTypeLocal == [(__bridge NSNumber *)sourceType intValue];
        CFRelease(sourceType);

        if (isMatch) {
            ABRecordRef group = ABGroupCreateInSource(currentSource);//ABGroupCreate();
            ABRecordSetValue(group, kABGroupNameProperty,(__bridge CFStringRef)name, &error);
            ABAddressBookAddRecord(addressBook, group, &error);
            ABAddressBookSave(addressBook,&error);
            gId = [NSNumber numberWithInt:ABRecordGetRecordID(group)];
            CFRelease(group);
            CFRelease(currentSource);
            break;
        }
    }

    CFRelease(sources);
    return gId;
}
