i have a facebook app that can be access through facebook canvas or directly via the url.
so everytime my user revisit my app, they have to click on sign in again, even if within the same session(For fb canvas only, session works fine for direct)
Is there any tutorial or scripts that i can add to my webpage using javascript to check if user is a register user, and if yes, auto sign them in?
I'm using rails3 and omniauth facebook gem. Thanks.

I have an app that all works fine for authentication and it uses Oauth2 (Google).
Now, I am struggling with the logout URL for this app. It works, but I am under the impression that it is possible to logout of it and remain logged into my gmail account please? Currently, ALL accounts are logged out of so the two gmail accounts need to go through login each time the app is used and log out is pressed.
I have read that this is possible but this is the URL that I am using to Log out
https://www.google.com/accounts/Logout?continue=https://appengine.google.com/_ah/logout?continue=http://news.bbc.co.uk
I am sure it can be done because I did it in a former role but do not have the code!
I am implementing a custom login button in my iOS app, using the FBSDKLoginKit CocoaPod, version 4.8.0. I already have log in working, but I can't figure out how to log out of Facebook. I am already calling logOut on an instance of FBSDKLoginManager, but that only seems to clear the currentAccessToken value. When I tap my login button again, I see a screen that looks like this:
I want to be able to log in as a different Facebook user. How can I achieve this?
In the new version of the Facebook iOS SDK (4.6 and above, I think) the default behaviour of login uses Safari View Controller. So if you are logged into Safari and have already logged into your app using Facebook, it will not ask for your credentials again and show you that screen. If you want to log in as a different user, then you will need to log out of Facebook in Safari in which case the login dialog should ask for your credentials. Also, you can remove the app from your app settings and try to login in which case it will show you the permissions screen. This behaviour of the login dialog probably follows from the best practices where a logout from an app should not cause logout from Facebook itself.
I want to let the user the option to like facebook page with this code generator :
https://developers.facebook.com/docs/plugins/like-box-for-pages
the problem is the using this code in iframe and uiwebview, facebook is asking the user to log again.
Is there way to use the access token from the facebook-ios-sdk login to prevent the user to login twice ?
the solution was to to tell the facebook sdk login method to log with webview from the app and not to login through the official facebook app.
this way, when the user like the page later, the access token already exist.
it's not perfect solution but works ok for one user.
I have a iPad home page app that I'm trying to integrate a facebook like button. Everything works fine if the user is already logged in, but if the user is not logged in the facebook login page takes over my app page and after login does not return to my app. Is there a way to make facebook login using an iframe?
My app is a web app not a native IOS app. It is setup with a manifest file and the user adds it to their home page. Because the app can have different URLs and all we want to do is provide like functionality, registering the app is not available to me.
What I want to know is there a way for facebook to open the login page in an iframe like the like dialog when the user clicks the like button? Right now I'm using the social plugin for the like button, but if the user isn't logged in to facebook the login page replaces my web app. Is there a way to make the login page use an iframe?
Wrapping it in a <div> worked for me
I have used latest FB SKD in my iOS app so users can use facebook account to login. Application open the FB app and comes back to my app perfectly fine. However, in some place in the app, i have to show/pull some people facebook page (safari based using WebView), but even user already used the Facebook account to login into my native ios app, but the page still ask user to login again and when they click login, it shows them the annoying FB username/pass page.
Is there anyway, that the FB safari based page can authenticate the user since it's already logged into my app using FB integration? do i have to include query or something. Please give me details how to solve this problem since i'm new in this..
thanks again for your help...

When the user switches to Facebook app to authenticate, it doesn't create a cookie for your UIWebView which is why it's asking to login again. Have the user authenticate inside the UIWebView without switching to the Facebook app.
What you're talking about also sounds like a similar thing that happens with Facebook dialogs not knowing about the current Facebook session.
If you authenticate your user via Facebook, try saying the Facebook object itself as an instance variable somewhere in memory so you can access it again (a property on a singleton controller, perhaps?).
Spawning dialogs from an authenticated Facebook object appears to let them use the dialog without reauthenticating iff you have a [FBSession activeSession]. So you'd also have to maintain an active FB session. But I'm not sure if this kind of solution will work since you didn't show specific code for how you're doing your web-based FB fetches.
