Twitter Single Account Logon iPhone

Hello is there a way to enable auto login for twitter using oAuth authentication. There have been similiar posts of how I could store username and password together with access token so the app logs into one account on Twitter.

Any specific advise of how i could implement it using would be very helpful. Should I consider NSUser defaults to store username and password etc

Yes, you can. Just check cookies in your code and make them like:

Clear_cookies=NO;

Please provide your source code, so that I can tell you in detail.
