如何在Quickblox iOS SDK中检查会话是实时的还是过期的? [英] How to check whether session live or expired in Quickblox iOS SDK?

问题描述

我知道，任何会话都将在对Quickblox服务器的最后一个请求(在2个小时之前发出)之后过期.创建会话时，我可以找到 [QBBaseModule sharedModule] .tokenExpirationDate ，但是我不确定它如何工作以及如何检查会话是否有效?

I know that, any session will be expired after last request (made before 2 hours) to the Quickblox server. When I create a session, I'm able to find [QBBaseModule sharedModule].tokenExpirationDate but I'm not sure how it works and how should I check for whether session is live or expired?

如果我创建一个会话，接下来的2个小时我会得到 [QBBaseModule sharedModule] .tokenExpirationDate ，现在我将在一个小时内向服务器发出请求，还要更新 [QBBaseModule sharedModule] .tokenExpirationDate 日期吗?

If I create a session, I'll get [QBBaseModule sharedModule].tokenExpirationDate for next 2 hours, now within an hour I'll made a request to the server, would it update [QBBaseModule sharedModule].tokenExpirationDate date too?

推荐答案

1. 通过检查 tokenExpirationDate .
在QuickBlox的每个响应中，
2. tokenExpirationDate 都会更新.答案是-是的.

1. By checking tokenExpirationDate.
2. tokenExpirationDate is updated in every response from QuickBlox. So answer is - yes.
