I have followed the iOS 9 Facebook SDK instruction to the letter and facebook login works great, but the app can only support one Facebook user.
I want to support multiple users, but seem to be stuck with whatever user I first logged in with through the Facebook SDK.
Scenario 1:
If I delete my app from the list of allowed apps on facebook website (in settings) and then activate the Facebook login (provided by the Facebook SDK) in my app, rather than allowing me to login in as a different user it asks if I want to "Continue" loging in as the last user that used the facebook login from my App. If I confirm it reauthorizes the app on my facebook account and logs me in as the last user that logged in. Here is the dialog I get when trying to login in after deleting the app from my facebook account.
Scenario 2: The app has been authorized on my facebook account. I chose to log out in my app. I call the facebook logout as shown
FBSDKLoginManager().logOut()
When I go to log in again using the facebook login button (provided by the Facebook sdk), rather than present me with a new facebook login screen it gives me the following:
I don't want to confirm login as the last user. Hitting cancel does nothing. Hitting confirm logs me in again as the last user.
Question: How do I force the facebook sdk to clear out the last users facebook credentials?
Thanks in advance!!
Logout, than set loginBehavior = FBSDKLoginBehaviorWeb when you login.
Reset Facebook Token Reference - Facebook SDK 4.0
When you set login behaviour to web:
loginManager.loginBehavior = .web
with every login you can auth with new credentials

I am working on app that needs facebook to login. In other means we are using facebook authentication in our app along with in app login screen.
So now at very first, I was able to login using my facebook account. When i first tried it, I have to provide both user name and my password to get login using my facebook account credentials.
Now after that I want to logOut from facebook account whenever user hit Logout button from our app. Here is what I am doing
AccessToken.current = nil
Profile.current = nil
LoginManager().logOut()
but it is not actually working. When I press again to login back, now I never see that screen where I gave facebook account credentials. its mean LogOut() function is not working.
Please help me this is weird behavior from facebook sdk
I'm upgrading Facebook SDK from 3.x to 4.x and need to log in as different Facebook users to my application (game) in order to check if FB requests work correct.
In 3.x login dialog switched to FB application, so I could change the user in the FB application and got new credentials for my login. Now I only got "You have already authorised..." message in a Safari-view login dialog.
I changed user in FB application several times as well as uninstalled my application in order to clean its local cache - nothing helps. My application always logs in as User 1, even if I logged in as User 2 in FB application.
How can I login as a different user (clear saved token, got a credentials dialog or something else)?
You need to log in fb from Safari and exit the user =)
I'm having an iOS app, need Facebook login to share something to wall. Everything is ok until I received new feedback from customer. Let me describe this case.
Apple have integrated Facebook into iOS system, user just needs to login via Setting, it is so easy for user. But my customer does not want to do that, they want user to login Facebook inside app and use it instead of Facebook of iOS system. Problem is here, there is a case: user has already logged in Facebook account A via iOS system, then user opens app and login Facebook inside app with other Facebook account B. After that, user shares a picture. Requiment is this picture should be shared on wall of Facebook account B (of app), but this picture appeared on wall of Facebook account A(of iOS system).
I just wonder do we have any solutions to resolve this case? Please give me any ideas you all have in mind after reading.
Thanks,
Ryan
I faced the same problem with Facebook SDK whenever a user login from any app using Facebook it change userid returned with the token which leads to share on the latest opened account.
if you open Facebook from a browser you will get this message from Facebook " we got confused please re-login "
so i took the same approach i saved user-id User(A) and whenever user share i check id coming with token if it changed i show " Facebook account changed please relogin " & i log all users out.

I am using the Facebook iOS SDK to allow quick sign-up of users in my app. Here is the flow:
User taps "Login with Facebook" button
Taken to Facebook app or Safari for login
Redirected back to my app
Show Sign-up for with pre-filled fields from FBGraphUser object
User creates account using data from Facebook
After they created an account, is it possible to authenticate with Facebook, and let them login to my app without having to enter the username and password they just created? How would the flow of that work?
Seems like I should be able to do the following:
User taps on "Login with Facebook" button
Authenticate with Facebook SDK
Return to app, and make a call to server, checking to see if there is a username matching the Facebook email
Allow the user into the app with no password, since they have authenticated with Facebook and have an account in our system.
Is this the correct way to do it?
That is very close. However, it is not enough to just check that the email/username is valid. It is strongly recommended to validate the token directly with Facebook as well.
See Use Facebook authentication token in API for a very similar concept and the Facebook docs about verifying token: https://developers.facebook.com/docs/graph-api/securing-requests.
I'm developing an iOS app that integrates with Facebook SDK. When I make the login for the first time with my facebook account it takes the following steps:
Jump to safari web login
Insert my credentials
After that I authorize the permissions that are requested
And then I go to the main menu of my application.
When I press the logout button, I run the following code:
- (void)logout {
[FBSession.activeSession closeAndClearTokenInformation];
}
With this code I can invalidate the session and clear the access token information. However, when i try to login again, my application jumps to safari web login and my account appears already as logged in (next picture).
If I want to login with another Facebook account, i can't do it. In other words, I would like to follow the steps that I said earlier or have a mechanism like "Not you?" that Facebook official app provides.
Any idea that what I have to do?
You're still logged in through Safari. Log out there (or clear your cache).
wrong, happens when not logged in safari and FB app.
