Quickblox: how find out whether the user is online?

Is there any way to find out whether the Quickblox user is online? I'm using Quickblox iOS SDK.

Solution

There are 2 ways:

Using REST API - here is a guide http://quickblox.com/developers/SimpleSample-users-ios#Online.5COffline_status
Using Chat contact list http://quickblox.com/developers/SimpleSample-chat_users-ios#Contact_list
