I have a textbox on my site where people can enter a tweet
when submitting if the user is not already logged in he will be redirected to twitter's page to login
however after this the original tweet that the user typed is lost. is there a way to keep this info?
is it true that with oauth I must redirect the user to twitter's login page? i can't have a popup? or put it in an iframe?
i would do it with $_SESSION if you are using php?

Can an application check if anybody is logged into Facebook application in mobile ,if logged in get the user email Id from that and use it in their application?
To get a logged in users email address, you would have to authenticate with the API and the user would have to approve you using the Oauth workflow.
You can display a customized login / connect button using the Facebook API but if I recall correctly, that is an iframe that is embedded in your page, and you never see the email from that.
tldr; No. You need to authenticate using the Oauth workflow and have the user grant you permission.
First you have to authenticate user and then you can get logged in user profile information. For that you have to use Facebook API. Please check below link.

How do I parse a webpage with login and password requirements to view the individual user's information, like facebook for example. I want my app to access to the individual facebook page, after entering login and password in the app.
By now I was able to parse usual webpages with TFHpple, but I have no idea how to pass the login and password requirements to get the page content.
Thank you very much in advance!
Usually the process for logging in is:
User POSTs data to a login form with username and password.
The server responds with a session cookie
Future requests include the session cookie and the server knows that the user is authenticated.
If you wan to do this login process on your user's behalf through our app, you'll need to save the cookies and send them on subsequent requests.
Why don't you use the Facebook iOS SDK:

I think it's a little bit strange from the architecture perspective that you want to parse the personal Facebook newsfeed, when there's the possibility to get the data via the Facebook API (given that you have the appropriate User Permission)...
I'm developing a desktop application which is supposed to allow users to login via Twitter.
There seems to be 2 ways to do so, that differ in a way oauth_verifier is returned to the application.
The first one is for web applications and oauth_verifier is returned as a url query parameter when redirecting user back to redirect_url.
The second one is using a PIN displayed to the user, which user enters to the app.
Now Facebook, for example, has a page facebook.com/connect/login_success.html , where FB can redirect a user with ouath_verifier as a query param (e.g. facebook.com/connect/login_success.html?code=<token>. Then I can read that param back from the browser's location field (I'm using an embedded browser).
So, is such a workflow possible with Twitter? Does it have a static page, where it can redirect user with oauth_verifier ?
I haven't been able to find such a page in Twitter's API docs, so I ended up using the main page twitter.com for the redirect. Everything works fine.
I have implemented Sign in with Twitter on my web site using DotNetOpenAuth lib using asp.net mvc 3.
My problem is that every time the user click Sign-in with twitter it redirects him to a twitter page (even if he is already logged in to twitter).
I saw that sites like www.pinterest.com avoids this somehow.
How can I avoid the redirect to Twitter sign-in page if the user is already logged in to twitter?
This is called Sign in with Twitter. Redirect users to https://api.twitter.com/oauth/authenticate?oauth_token=xyz instead of https://api.twitter.com/oauth/authorize?oauth_token=xyz. If the user is has an active session with twitter.com and has previously authorized the application they will silently be redirected to the callback url.
Is there a parameter I can pass to https://www.facebook.com/dialog/oauth that will force the user to login again?
The problem is if the user is logged into Facebook, it will redirect transparently back to my site, even if the user wants to use a different Facebook account.
Twitter's OAuth API accepts a "force_redirect=true" parameter which does what I want, but I can't find one for Facebook.
I think "auth_type=reauthenticate" is the option you are looking for.
