I have been developing a chat application using Quickblox framework. I have been reading and testing many official sample projects (including Q-municate) but i do not find a way to block / ban user. Is there a method for achieving this functionality ? Do i need to implement Custom Objects ? Thanks.
You can use Custom Objects for now. For example, create a class and store IDs of blocked users there. And then develop appropriate logic on the client side.
QuickBlox is going to release 'true' block list soon, also it will be available within Q-municate project
