Question

当我运行以下代码时，我在最后一个try语句中收到此错误：

错误域= CNErrorDomain代码= 200“更新的记录不存在” UserInfo = {NSLocalizedFailureReason =保存请求失败，因为它更新不存在或已被删除的记录。 CNInvalidRecords =（ “”），NSLocalizedDescription =更新记录不存在}

我不明白这个错误。如你所见，CNGroup的记录显然存在，因为我刚创建它没有错误。我还检查了模拟器。联系人和小组都存在。

    let store = CNContactStore()

    let defaultContainerIdentifier = store.defaultContainerIdentifier()

    let cnMutableGroup = CNMutableGroup()

    cnMutableGroup.name = "Temple5"

    let groupIdentifier = cnMutableGroup.identifier

    let cnMutableContact = CNMutableContact()

    cnMutableContact.familyName = "Ralph5"

    cnMutableContact.givenName = "Rolfson5"

    let contactIdentifier = cnMutableContact.identifier

    let saveRequest = CNSaveRequest()

    saveRequest.add(cnMutableGroup, toContainerWithIdentifier: defaultContainerIdentifier)

    saveRequest.add(cnMutableContact, toContainerWithIdentifier: defaultContainerIdentifier)

    do {

        try store.execute(saveRequest)

    } catch let error as NSError {

        print(error)

    }

    let predicateGroups = CNGroup.predicateForGroups(withIdentifiers: [groupIdentifier])

    var cnGroups: [CNGroup] = []

    do {

        cnGroups = try store.groups(matching: predicateGroups)

    } catch let error as NSError {

        print(error)

    }

    let cnGroup = cnGroups.first!

    let predicateContacts = CNContact.predicateForContacts(withIdentifiers: [contactIdentifier])

    let keys = [CNContactGivenNameKey, CNContactPhoneNumbersKey]

    var cnContacts: [CNContact] = []

    do {

        cnContacts = try store.unifiedContacts(matching: predicateContacts, keysToFetch: keys as [CNKeyDescriptor])

    } catch let error as NSError {

        print(error)

    }

    let cnContact = cnContacts.first!

    saveRequest.addMember(cnContact, to: cnGroup)

    do {

        try store.execute(saveRequest)

    } catch let error as NSError {

        print(error)

    }

尝试传递nil作为容器标识符。

saveRequest.add(cnMutableContact, toContainerWithIdentifier: nil)

错误域= CNErrorDomain代码= 200“更新的记录不存在”
