Sharekit Twitter problem in real device

I'm using Sharekit on my iPhone app, I used oAuth method, after many problems it worked finally in the simulator, but when I try it on a real iDevice I get this error :

" Request Error There was a probl开发者_运维技巧em requesting authorization from Twitter "

I think I remember such a problem. I think you can try changing your device's data/time to automatic. I hope it helps.
