Quickblox session expiration while on background.

问题:

When the user goes to background, I log out the user from chat. When the user comes back from background, I log the use again in chat.

This works well but not every time. Sometimes when the user keeps the app more then 2 hours in background, the session expires and it doesn't seem to revalidate automatically when the user comes back from background, even with this piece of code:

[QBSettings enableSessionExpirationAutoHandler:YES];

Should the app revalidate the session/QB login automatically with enableSessionExpirationAutoHandler on even when coming from background?

Is there another way to handle session expiration while in background? Can anyone please suggest me some ideas?

回答1:

Any session will remain valid for 2 hours after the last request to QuickBlox. To check a session's expiration date use this next snippet of code:

NSDate *sessionExpiratioDate = [QBBaseModule sharedModule].tokenExpirationDate;
