I am building an app, which uses facebook authorisation services. However, I am facing problems in two cases
The user is sent to the facebook app for giving permission. Instead, she presses the home button and again opens my app.
In this case, I need to do two things:
a. Re-show her the login page (and remove the animation from that page): For this I need to know that the user has come back to the app without logging into fb.
b. Cancel the last request sent to fb: If user tries to login again, my app sends two requests to the fb authorisation system, which leads to two popup windows in the fb app and also gives back multiple calls to my app.
The user presses the cancel button: In this case fb app is not re-directing to my app. I read that this was a bug and has been fixed; however, this still this does not work for me. Any suggestions?
I have tried to search for similar Q on the forum; however, have not been able to find exact answer. Please let me know if I missed looking at relevant question.
If you're using the Facebook SDK 3.1 for iOS, then
- (void)applicationDidBecomeActive:(UIApplication *)application {
[FBSession.activeSession handleDidBecomeActive];
}
Will cancel the auth request if the user happened to cancel the auth flow via doing something like hitting the Home button. You can then reset by showing your login view again.
The (2) problem should be fixed if you upgrade to the latest Facebook iOS app.

I have a web application (React js with Kotlin backend) that has normal email + pw (plus PIN) login, and it also supports 3rd party authentication (Google and Facebook). It works on mobile and web, however, when I open my webpage through Facebook app - which opens it's own browser - and try to log in with 3rd party authentication, I can click on that "Continue as me" button, but then the page refreshes and I'm not logged in. I saw the same thing happen on other sites too, e.g. Figma, Pinterest, etc. I thought it's impossible to log in this way anymore, however, I just noticed that you can actually log in to Stackoverflow this way (so facebook app -> facebook browser -> stack overflow -> 3rd party auth and it works).
Has anyone figured it out how it was possible for Stackoverflow to do this?
Ok, I found the solution. The problem was that when a user clicked on 'Login with FB' button on my site, I sent a request to fb to get back a content of a login window and I created a pop up window where I rendered it, I put on a listener on that pop up window and once it was done, then I got the access token and sent it to backend and logged the user in. On a normal browser it works perfect (both pc and mobile) but as I mentioned above it didn't work in an in app browser like facebook app.
The issue was that facebook app opens a website in it's own browser that doesn't handle any pop ups, so after a successful authentication I saw that nothing happened and it was because we were not redirected to the original window where we should have, and it had the token in the url. So the solution was instead of making this pop up window for FB login, just redirect the user to the fb login page (and stay on the same window), and once the login is successful, just handle the token as is.
When a user is not logged in and they navigate to a page tab made with our app, they get an obtrusive dialog asking them to log in:
This has nothing to do with http vs https, the app is not in sandbox mode, there is nothing in the tab asking for a login or user information, etc. I've gone through the app settings at least a half dozen times now, and nothing is wrong there. Aside of urls, the settings are identical to another app I have that does not suffer from this problem. I'm stumped!
Edit: here is an affected tab: https://www.facebook.com/StaticHtmlThunderpenny/app_203351739677351
This message is not about login to your app, but Facebook in general.
So my guess would be that the page your app is installed as page tab app on is restricted in some way – by age, location, or for having alcohol-related content. And then of course Facebook asks for login, because otherwise they can not determine whether or not the (as of now still “anonymous”) user qualifies to see the page.
So go check the page settings.
This is actually not app related question.
This is thumb rule!! To access any app on Facebook, you need to log in to Facebook. You can see Facebook page without log in. But for facebook apps, you should be authentic user.
with this issue in my own experience that I came across some years back with a facebook app that I was running, if this doesn't relate to any of your other social networking apps then am aligning two set of possibilities and solution.
The user might have not properly logged out as "written" in the app for the users logout stage.
Solution would be that the user logout as expected before closing the app.
The user might have set up an automatic login prompt which was removed by the app when it was been updated automatically. (If you do get me???)
Solution would be to monitise your app on updates and login informations or better still just login and logout ask intended by the app and for security reasons.
Lastly I would say that automatic bookmark database should be added to the server part so current pages as the user uses the app would be saved after logout or login stage. Thank you, hope this helps and if not let me know what am missing.
I have Facebook's SSO working properly in my iPhone app and most of my users have not been experiencing any issues. However, a small number of them have been reporting errors with Facebook Connect and not being able to create an account. After an email exchange with one, we determined that the app permission toggle under Settings->Facebook was somehow set to disallow my app from using Facebook.
I have since added an error message telling the user this might be the case but my question is how did this switch get toggled in the first place? It would seem that a user would have to manually toggle this switch, right? I also looked for an API method that might do this e.g. rejecting Facebook SSO the first time a user saw the dialog asking for permission; I could not find any such code.
Any ideas? I'm hoping this problem will solve itself with the error dialog I've put in but if possible, I'd like to remove this issue altogether.
As far as I know, using the native dialog with iOS6 and rejecting the permissions request (the first one, at least, not sure about requests which are asking an existing user for more permissions) will toggle that switch
If you need to debug, try uninstalling the app from your facebook profile (a HTTP DELETE request to /<USER ID>/permissions will do this, or you can do it in the facebook app settings), remove the iOS app, then install it and try to connect for 'the first time' again
Javascript authentication works great on browsers but once I use the website on mobile, I always get this error on the login popup.
Sorry, the application you are using is misconfigured for Facebook integration. Please download the newest version of the application.
Instead of showing the usual login popup, it goes to m.facebook.com and it produces this error. Whats interesting is clicking on the spanish link, makes it work again.
--EDIT--
After doing some research and tinkering, ive nailed it down to this:
<fb:login-button registration-url="http://www.example.com/page#register" onlogin="authenticate.facebookLoginCallBack()"></fb:login-button>
Its possible the pound sign blows it up. I need the pound sign because i dont want to redirect off the page,instead i want to trigger a js registration popup.
My guess is that the # gets into the redirect-url, and then must somehow get transformed again on its way to getting redirect to m.facebook.com and that makes it fail there.
--EDIT--
I thought about redoing the flow by creating my own button and calling FB.login, but there is no way to tell the API to stop at login, and load my own registration. The problem is summed up here Registration flow using FB.login
Realistically it seems we are only provided with one option here:
https://developers.facebook.com/docs/plugins/registration/
Login + Registration Flows
and it doesnt work in my situtation
VISUALS
Typically the user clicks on this button
Then they see this dialog. (Notice it says www.facebook.com in the url)
But they see this dialog on mobile. (This is loading from m.facebook.com)
I am trying to implement Facebook functionality on iPhone using Facebook API. In my application I can open the Login screen, but when I enter Email and password and press "Connect" button there nothing is to be happen. And after sometimes I will be back in my previous screen. I have used FBConnect bundle. I can't understand why I cannot login in Facebook? Even I get that login screen but that connect button cannot do anything.
Please help me...
You need to post your code, so we can see how you have attempted this.
From what you have explained though, it seems like you're not implementing the delegate call back for the login dialogue. You need to implement
- (void)session:(FBSession *)session didLogin:(FBUID)uid;
and possibly these two methods as well.
- (void)dialogDidSucceed:(FBDialog *)dialog;
- (void)dialogDidCancel:(FBDialog *)dialog;
They are the call backs your session delegate object will receive when certain actions have been completed.
