如何在Quickblox iOS SDK中检查会话是实时的还是过期的？

Question

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?

1. How to check whether session is live or expired?

2. 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?

Answer 1

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