authenthicate mgtwitterengine with username and password without webview

I am using Ben Gottlieb his implementation of MGTwitterEngine and OAuth (https://github.com/bengottlieb/Twitter-OAuth-iPhone). When I use his implementation, I get a webview with a twitter loginscreen, and I have to login and grant the application. Is it possible to do the authentication myself? So don't use the webview, but do it all in code, with开发者_运维知识库 username and password typed in a form.

This can be done by using Twitter's xAuth authentication mechanism. This is however not as simple as you need to ask Twitter permission to use xAuth.
