I set up a Facebook login package for my meteor project. It is supposed to work on mobile, but when the iPhone app finishes logging the person into Facebook, it just shows a blank screen.
I have tried:
Meteor.loginWithFacebook({loginStyle: "redirect" }
But it still doesn't work. Any ideas?
The app takes you to the sign in page, but after you sign in, it doesn't redirect back to the app. It just shows a blanks screen.
I figured it out. Facebook now defaults to API version 2.3 and there is no way to change it to an earlier version in the Facebook App section.
2.3 is not supported by the Facebook accounts system on Meteor.
I just so happens I had an old Facebook app that was set to use API version 2.0
If I didn't have that old app then I would have been out of luck.
If you found this answer useful please arrow up the question and answer. Thanks!

Today, on my Facebook app, links appear to be broken. Everytime you click a link (to another page of the application, not external), Facebook returns the user to the login prompt, even if the user has already logged in.. I usually use relative urls, but if I set absolute, the link doesn't work too, but in this case the page doesn't change...
Anyone having same problems? Any ideas? I just can't find solutions..
Edit: for "Facebook app" I mean an iframe application that runs on Facebook site, not the Facebook application for a mobile device
Solved :) The problem was I used on old versione of the PHP SDK. I've updated the SDK with the latest version and also the Login part of the code; now it's ok. Thanks all for your help ;)
Did you tried to reinstall the Facebook app? Also if you use Android you can delete the cache on your phone.
Everytime you click a link (to another page of the application, not external), Facebook returns the user to the login prompt, even if the user has already logged in..
Do you have Authenticated Referrals turned on for your app?
Otherwise, you must be triggering login yourself somewhere in your app. If so, check the conditions under which you are doing so, and if your app recognizes a logged in user correctly, or if maybe there is some kind of cookie problem.
If that doesn’t help you to figure it out on your own, please update your question with relevant code.
I got a Facebook Page Tab App (using Timeline). It works fine in desktop version of Facebook, but when its Wall Post is clicked in Facebook App, it returns "The page you requested was not found" and forwards to an inaccessible link:
https://m.facebook.com/4oh4.php?id=282832318433409&_rdr
How come? I don't expect mobile version will be the same as desktop version, but I don't expect it reports the page cannot be found.
Page tabs apps are not supported (as of April 2012 anyway) on mobile browsers - mobile apps are, but they're not tied to the Page and need to be manually linked-to or bookmarked, the tab functionality simply doesn't exist now.
Tabs aren't supported via the app or mobile site. Best you could do is add the query parameter "ref=ts" to prevent the page from switching to mobile. It helps in the browser but not the app itself.
So add ?ref=ts to the end of your app url and at least mobile users can see it in their browser.

You can work around this problem by using a Canvas Page to redirect mobile users to a mobile site and desktop users to the page tab.
Detailed instructions here:

You can access to your app using the next link https://apps.facebook.com/YOUR-APP-ID
In this way, you can access from a desktop or a mobile with no problem
I'm seeing a problem requesting permissions with Facebook connect on iPhones. Everything had been working fine and then it just started out of nowhere. I can't seem to sort it out, so I posted it here to see if anyone's experiencing the same issues? I'm trying to log users into a mobile website and here's what I'm seeing:
On Android, everything is A-OK, as are regular web browsers.
On the iPhone 3, users get the login page ok, but are not redirected to the request permissions page, just to mobile facebook. If they leave and come back and click on the login button again, they are taken to the request permissions page, and after they allow/don't allow, they are taken back to our site. This is also the same for iPad users
On the iPhone4, users get the login page ok, but are not redirected to the request permissions page, just to mobile facebook. If they leave and come back, they are taken to the mobile facebook site and never are prompted for their permissions.
Highlights:
Everything was fine 3 weeks ago
Everything is still fine on Android using the very same FBConnect url, but it blows on iOS
What happens on iPhone 3 is different that what happens on iPhone 4
I've tried doing this with 3 different urls, but StackOverflow will only let me put 2 in here because I'm a new user:
http://www.facebook.com/dialog/oauth?client_id=[OUR_CLIENT_ID]&redirect_uri=[OUR_URL]&display=wap&scope=email,user_location,read_friendlists,publish_stream,offline_access
http://m.facebook.com/dialog/oauth?client_id=[OUR_CLIENT_ID]&redirect_uri=[OUR_URL]&perms=email,user_location,read_friendlists,publish_stream,offline_access";
The other URL was similar to these, but used the graph API
Anyone have any ideas?
Thanks!
Facebook has since removed the WAP interface and replaced that with Javascript SDK interfaces for Android and iOS, and now normal wap enabled phones have been shut out.
We've got a few pages that use the apple-mobile-web-app-capable meta tag (value="yes"), but on a login page that allows Facebook Connect, you get a blank page when you click on the connect button. I've seen this posted on the old FB developer forums, but with no relevant responses. Has anyone figured this out already?
This could be a bug in facebooks API. I don't think they've tested their API in iPhone web app mode. Issue can be followed here: https://developers.facebook.com/bugs/317323871621290
The issue have been raised here on Stack Overflow a couple of times too:
How do I get back to the iPhone web app after having logged in with Facebook Connect?
blank white screen after FB login via web app?
I'm building an iPhone app that has some social features. I've managed to get the user to log-in to Facebook within my application.
I've also implemented a webview that loads a facebook iPhone-optimized page. What I now want to do is my user to be logged-in within the webview without having to log-in twice (once in the app and once in the webview)
I've tried a few things playing around with the access_token in the URL but it didn't work.
Does anyone know if it is possible to implement that and how to do it?
Thanks in advance for your help
Short answer: You're probably not supposed to be able to do that.
The idea is that your app should only store an authentication token that lets you do stuff as your app (e.g. post to the wall as your app). On the web version, the user is logged in to facebook and facebook additionally passes an authentication token to your website; on the iOS version, I think you never get the Facebook session cookie, and I'm pretty sure you need the Facebook session cookie to be logged in to the web side of things (especially since it's designed for the browser — logging out of Facebook logs you out of Facebook Connect on all sites).
There are loads of things you can do to work around this — it's trivial to just ask the user for a username/password (and the whole idea of a "trusted UI" inside a UIWebView inside your app is flawed, despite Facebook's claims).
The "right" thing to do is to implement everything using calls to the iOS SDK so you don't have to bother with the web side of things.
were you testing your app on the simulator or on the device? The reason i ask is because im trying to get the app to stayed logged into fb which it does, sorta...it still pops a fb dialog saying it logged in fine and the user has to click on an OK button.
I havent had time to test it on the device but i think it may have to do with the fact that with the OAuth 2.0, with 3.2.x or >...if the fb is installed, it uses the fb-app login but if its not installed it uses the safari web login.
Since simulator doesnt have the fb app installed, it actually uses the safari web login (i humbly deduced) which would otherwise store a cookie and maybe it doesnt do so on the simulator..dunno, im still looking for the answer on that one :)
