Hello, I have an iphone applicaton in which I am using XAuthTwitterEngineDemo source code downloaded from github. Primarily it was working fine. Suddenly it stopped working. When ever I login it gives Authentication error like "Please check your username and password and try again". I am giving correct username and password. It was working fine previously. Even tried another consumer ke and sectet key but it stills gives same error.
I am not getting any idea about that. What should I do. Please help me
