Twitter Authentication OAuth or XAuth

I am trying to integrate Twitter into my application. My basic requirement is to have custom login screen and as twitter requires only OAuth. As per Twitter documentation I found these

1. MGTwitterEngine(Downloaded but its missing entire OAuth library, hence could not compile)
2. bengottlieb(cannot customize login as it is web based)
3. XAuthTwitterEngine

   XAuthTwitterEngine looks promising but XAuth is disabled by default and need permission from Twitter So my questions are

1) what type of information I have to provide to Twitter in order to get approval for enabling XAuth

2开发者_StackOverflow社区) if XAuth is not recommended then how do I achieve my basic requirement mentioned about.

i hope my question is valid. Thanks so much.

You can also check out my Twitter client. It was specifically written for 'Share on Twitter' functionality. It uses XAuth.
