ios - 更新 Kinvey 上的现有用户

Question

我很难更新已在 Kinvey 上注册的用户。

例如，如果我使用此代码注册新用户:

KCSUser.userWithUsername(
"kinvey",
password: "12345",
fieldsAndValues: [
    KCSUserAttributeEmail : "kinvey@kinvey.com",
    KCSUserAttributeGivenname : "Arnold",
    KCSUserAttributeSurname : "Kinvey"
],
withCompletionBlock: { (user: KCSUser!, errorOrNil: NSError!, result: KCSUserActionResult) -> Void in
    if errorOrNil == nil {
        //was successful!
        let alert = UIAlertView(
            title: NSLocalizedString("Account Creation Successful", comment: "account success note title"),
            message: NSLocalizedString("User created. Welcome!", comment: "account success message body"),
            delegate: nil,
            cancelButtonTitle: NSLocalizedString("OK", comment: "OK")
        )
        alert.show()
    } else {
        //there was an error with the update save
        let message = errorOrNil.localizedDescription
        let alert = UIAlertView(
            title: NSLocalizedString("Create account failed", comment: "Create account failed"),
            message: message,
            delegate: nil,
            cancelButtonTitle: NSLocalizedString("OK", comment: "OK")
        )
        alert.show()
    }
  }
)

我将如何更新 KCSUserAttributeGivenname 或 KCSUserAttributeSurname。

如有任何帮助，我们将不胜感激。谢谢

我已经弄清楚如何成功更新用户。它看起来像这样:

        KCSUser.activeUser().setValue("John", forAttribute: "first_name")
        KCSUser.activeUser().setValue("Doe", forAttribute: "last_name")

然后您只需调用 .refreshFromServer 来更新服务器并调用 .saveWithCompletionBlock 将更新的更改保存到后端。
