If the user types the correct datails, the message will be posted otherwise display some alert message. And i have one doubt, which API is used to better in the appln?(MGTwitterEngine,Oauth etc.,). I am very new to this topics. So please guide开发者_C百科 me. Is there any sample code or tutorials are availble for validation?.

I hope definitely it will help you.

Twitter Request Package is not enough to implement TWitter (to validate) login authentication and for implement that before you should be known about OAuth or XAuth process. I successfully implement that with XAuth authentication after period of long time. If you follow the link then you can do twitter validation as you expect.Click Here
