I am trying to share a link in an Mac App in Facebook/twitter and I would like to check if the user has the account in settings. If the account is not in settings, I would like to do this sharing by web browser.
I try the following code, because Apple documentation said that you can check if the account is configured using canPerformWithItems with the nil parameter. (facebookSharingService is NSSharingService)
NSMutableArray *shareItems = [self prepareItemsToMessage];
if ([self.facebookSharingService canPerformWithItems:nil])
{
/*
Perform the service using the array of items.
*/
[self.facebookSharingService performWithItems:shareItems];
}
else
{
[self shareFacebookByWebBrowser];
}
Using this code, pop up appears saying that I need to configure the account. How can I check if the account of Facebook or Twitter in in Settings or not?

I think this is because Facebook just made some changes to their login process.
A few days ago, my air app was working with the FacebookDesktop class from the facebook-actionscript-api. Today I opened the project, and noticed that the Facebook login screens are a little different than when I started building my app. After I type my userID and password in, I grant the app access to my public profile, friend list and photos. Then another screen comes up where I grant the app permission to post to my friends on my behalf.
Then the window closes, and I get 'OAuthException 2500 An active access token must be used to query information about the current user.'
When I sign into Facebook through a browser, I see that my app shows up under "Your Apps" but I can't log in and do anything through my app.
I'm using Adobe Flash with GraphAPI_Desktop_1_8_1.swc on OSX Lion.
Here is my code:
public function MyApp(){
FacebookDesktop.init(APP_ID, onInit);
}
protected function onInit(result:Object, fail:Object):void {
if (result) {
trace("onInit, Logged In\n");
} else {
trace("onInit, Not Logged In\n");
var permissions:Array = ["publish_stream", "user_photos"];
FacebookDesktop.login(onLogin, permissions);
}
}
protected function onLogin(result:Object, fail:Object):void {
if (result) {
trace("Logged In as:");
trace(FacebookDesktop.getSession().user.name);
} else {
trace("Login Failed");
trace('code: '+fail.error.code); //code: 2500
trace('message: '+fail.error.message); //message: An active access token must be used to query information about the current user.
trace('type: '+fail.error.type); //type: OAuthException
}
}
I get the same results when I use the FlashDesktopExample provided in the SDK (modified with my app ID of course).
Any help would be great! Thanks in advance!
I ran into this problem, too: the success URL did not have any parameters.
Cadderly82 is correct; it's a problem with secure navigation. Turning off my Facebook account's "Secure Browsing" option fixed the problem, but I didn't want to have to require users to do that.
I was able to solve this by setting ALL of the FacebookURLDefaults values to use "https://".
Now I get a valid user-access-token in the success URL; and I get valid values regardless of my facebook account's secure-browsing setting.
I have figured out the problem:
The LoginWindow class sets the token based on the uri.
This worked fine until the LOGIN_SUCCESS_URL (http://www.facebook.com/connect/login_success.html) and the LOGIN_SUCCESS_SECUREURL (https://www.facebook.com/connect/login_success.html) pages stopped including the access token in the uri.
Hence, the token is never set. Even though my app shows up under the 'Your Apps' section in Facebook after I login, my app still can't do anything without a token.
I have two solutions:
The easiest is to change the LOGIN_SUCCESS_URL and/or the LOGIN_SUCCESS_SECUREURL properties in com.facebook.graph.core.FacebookURLDefaults like the following.
beginning on line 82:
public static var LOGIN_SUCCESS_URL:String = 'http://www.facebook.com/connect/login_success.html';
public static var LOGIN_SUCCESS_SECUREURL:String = 'https://www.facebook.com/connect/login_success.html';
Change to:
public static var LOGIN_SUCCESS_URL:String = 'http://www.yourwebsite.com/';
public static var LOGIN_SUCCESS_SECUREURL:String = 'https://www.yoursecurewebsite.com/';
of course you would use your own website - not 'http://www.yourwebsite.com/'. I tried it using http://localhost/ and it worked great.
Another solution is:
Change com.facebook.graph.windows.LoginWindow with the following code. I have made some changes to my files, so please forgive me if the line numbers are different than what they are in a fresh copy of the SDK.
around line 143:
change:
vars.redirect_uri = FacebookURLDefaults.LOGIN_SUCCESS_URL;
to:
vars.redirect_uri = 'http://localhost/';
In production code, you probably want to use your own website address instead of localhost, but I used localhost for testing purposes.
Then, in the handleLocationChange function (should be around line 168) add this to the else if statements:
}else if (html.location.indexOf ('http://localhost/') == 0) {
loginCallback(getURLVariables(), null);
userClosedWindow = false;
html.stage.nativeWindow.close();
html.removeEventListener(Event.LOCATION_CHANGE, handleLocationChange);
}
As I said before, change localhost to your website address.
I hope this helps!
I was having the same problem for random users and I don't really know if it is a Facebook problem with secure navigation:
Check user properties in Facebook: Security Settings > Secure Browsing
(www.facebook.com/settings?tab=security)
For users with "disabled" state it works fine.
For users with "migration" state it gives the error.
For users with previously "enabled" state it works fine.
When I tried with users in "migration" state and changed to "disabled", it worked fine.
Then if I turned it "enabled", the "migration" state is gone and marked as "enabled", but the error it's still there.
So I guess this is the problem, but don't know how to fix it.
alot has change in a year this is what i think the answer is now
you need a token to login FacebookDesktop.getSession().accessToken
public function MyApp(){FacebookDesktop.init(APP_ID, onInit, FacebookDesktop.getSession().accessToken); }
I have app that sharing photos on Facebook when I put my Facebook App ID in the project.plist I got the login window but not the allow window and there is no picture posted on Facebook which I think it is related to a mistake in creating the Facebook app.
It is the first time I create a Facebook app and I'm not sure what did I miss, let me explain to you what I did so you may be able to help me :
1- I put the app name and the app NameSpace
and create the app ID and secret .
2- Disabled the Sandbox Mode.
3- At the (Native iOS App) I added my app Bundle ID, iPhone App Store ID number, enabled the Facebook login and disabled the Deep linking.
4- At the Permissions : I choose Friends for the Default Activity Privacy, added to Users & Friends Permissions : ( email,user_status,publish actions ),
added to Extended Permissions :( photo_upload )
choose the ( Query String…) for the Auth Token Parameter , and enabled the Authenticated Referrals.
5- At the Advanced : I picked the (web) at Authentication with blank (Deauthorize callback URL) ,
*App Restrictions : Age Restrictions (Anyone 13+) and enabled the Social Discovery.
*Migrations : I only enabled ( Remove offline_acces permission, Explicitly Shared OG Stories and Picture As Dictionary ).
*Security : all blank and set No for (Set Client Token).
Now as you see, do you think I missed something? or did I do something wrong?
Do I need to add a website for the (Mobile Site URL) at the (Mobile Web) in the Basic Settings, if so what URL do I need to add ? is it the URL of my App on itunes ? what do I need to do?
Please I need a help, thanks in advance.
Have you followed all these steps described in Getting Started with the Facebook SDK for iOS?
Have you add -sqlite3.0 to your Other link flag?
And then you should not forget to Add the FBSession to your AppDelegate:
- (BOOL)application:(UIApplication *)applicationopenURL:(NSURL *) urlsourceApplication(NSString *)sourceApplicationannotation:(id)annotation {
// attempt to extract a token from the url
return [FBSession.activeSession handleOpenURL:url];
}
And also these code in AppDelegate:
- (void)applicationWillTerminate:(UIApplication *)application {
// if the app is going away, we close the session object
[FBSession.activeSession close];
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
// We need to properly handle activation of the application with regards to SSO
// (e.g., returning from iOS 6.0 authorization dialog or from fast app switching).
[FBSession.activeSession handleDidBecomeActive];
}
Though, there is such a question Facebook Error (7) iOS 6 it's already closed without any answer!
While obtaining an access to user's facebook account I've got an error:
error is: Error Domain=com.apple.accounts Code=7 "The Facebook server could not fulfill this access request: The proxied app is not already installed." UserInfo=0xa260270 {NSLocalizedDescription=The Facebook server could not fulfill this access request: The proxied app is not already installed.}
I'm performing a request like this:
self.statusLabel.text = #"Waiting for authorization...";
if (self.accountStore == nil) {
self.accountStore = [[ACAccountStore alloc] init];
}
ACAccountType * facebookAccountType = [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
NSDictionary * dict = #{ACFacebookAppIdKey : FB_APP_ID, ACFacebookAudienceKey : ACFacebookAudienceEveryone};
[self.accountStore requestAccessToAccountsWithType:facebookAccountType options:dict completion:^(BOOL granted, NSError *error) {
__block NSString * statusText = nil;
if (granted) {
statusText = #"Logged in";
NSArray * accounts = [self.accountStore accountsWithAccountType:facebookAccountType];
self.facebookAccount = [accounts lastObject];
NSLog(#"account is: %#", self.facebookAccount);
self.statusLabel.text = statusText;
[self postToFeed];
}
else {
self.statusLabel.text = #"Login failed";
NSLog(#"error is: %#", error);
}
}];
What does this error means?
I've solved this problem!
It was because I do not pass permissions array!
Though the ACAccountStore class states that this parameter is optional, it is not!
More over the application could launch and ask for basic permissions(as it is implied)!
So, you must always pass a permissions array.
Here's also a description of error codes returned by account store:
typedef enum ACErrorCode {
ACErrorUnknown = 1,
ACErrorAccountMissingRequiredProperty,
ACErrorAccountAuthenticationFailed,
ACErrorAccountTypeInvalid,
ACErrorAccountAlreadyExists,
ACErrorAccountNotFound,
ACErrorPermissionDenied,
ACErrorAccessInfoInvalid
} ACErrorCode;
(I've got ACErrorPermissionDenied here)
We had the same problem and after taking a closer look at the iOS facebook documentation ad
https://developers.facebook.com/docs/howtos/ios-6/
I noticed the following paragraph:
Note, to use iOS 6 native auth, apps need change the way they request permissions from users - apps must separate their requests for read and write permissions.
I must have read over that one several time but it contained the solution:
You have to do multiple request for access if you want to grant write (publish access). So now we first ask for permission 'email' to get read permission and then for 'publish_action' to be able to post to the timeline.
The error message is not clear since "app" could be your iOS app? Facebook.app on the phone? Facebook app? The "proxied app" is the Facebook app, and "not already installed" means, it's not yet been associated with the Facebook user online in terms of permissions.
The first time your Facebook app connects to the users Facebook account, you must specify the basic info value(s) in your ACFacebookPermissionsKey key of the options dictionary. Other Facebook SDK's past and present such as the Javascript or PHP libraries by default supply basic info as the key, so you never had to. It seems the native integration in iOS doesn't do this, thus, if when the user first connects your app to their Facebook account with no permissions supplied, you get this error.
After you are given access, i.e. - after the user is connected to the app in their privacy settings online, ACFacebookPermissionsKey does as Apple document, become optional.
It's all a little confusing when you start to try and use the native Facebook integration...
Using the native Facebook integration you must provide one of the following keys which are basic info keys: email, user_birthday, or user_location.
To quote Facebook (source):
To create this basic connection using the iOS 6 native Auth Dialog,
apps must request access to a user's basic profile information by
asking for one of email, user_birthday, or user_location permissions.
After experiencing this error on one of my devices (after seeing the correct, expected iOS alert view asking for me to approve Facebook access to my app):
'The Facebook server could not fulfill this access request: Invalid application ID.'
I finally found the problem.
Although it initially appears to be a problem with the Facebook app setup on the FB developer site it turned out that my device's iOS Facebook account no longer had a valid password associated with it - this can happy when users restore an iOS backup to a new device. Once I sorted that in my device settings everything worked as expected.
I've not experienced any problems requesting 'publish_stream' in the first FB permissions access request - I actually think the real problem here is that the error messages are so random that they don't help developers to locate the source of the errors we're experiencing thanks to Apple and Facebook's lack of unity!
A few more things that one can try other than the above suggestions is checking your app settings on facebook.com here -
https://developers.facebook.com/apps/<*APP_ID*>/summary
Make sure that the SandBox Mode is set to Off
Also,
Under "Select how your app integrates with Facebook"
Select-> Native iOS App
Set your Bundle ID
You can set any temporary integer value for iPhone/iPad App store ID
Set Facebook login to Enabled
Listed Platforms is Native iPhone App &/or Native iPad App
Save changes and try after some time as it might take a few minutes for facebook to sync the changes to all its servers.
My app should implement login with facebook but I have noticed that every time I want to login the facebook tell me you are already authorize this app , the question if I already authorized the app the facebook should return automatically without pressing the okey button as I saw in other applications ?
see the attached image
I fixed my problem by doing the following steps :
1- login to your facebook as admin to your app.
2- go to https://developers.facebook.com/apps/YOUR_FACEBOOK_APP_ID/summary.
3- go to settings > basic > Native IOS app
4- set the Configured for iOS SSO: to enabled
In iOS/Android the FBAccessToken's expiration time is up to 60 days. When you do FBLogin in your app you get the access token. once you get the token you should not do login again(otherwise you will be prompted already authorized this app since your app has already been given an access token earlier which is not expired ). You should reuse the unexpired access token.
Like this :
if FBSDKAccessToken.currentAccessToken() != nil {
print(FBSDKAccessToken.currentAccessToken().userID)
print(currentAccessToken().tokenString)
//OR call the *FBGraphRequest*
}
Note: for in-App browser login (SVC: Safari View Controller)
see more:
https://developers.facebook.com/blog/post/2015/10/29/Facebook-Login-iOS9/
and
https://developers.facebook.com/docs/reference/ios/4.9/class/FBSDKLoginManager/
You need to make sure that your app has the proper URL Prefix in your Build Settings. Also make sure that the URL Prefix matches your Facebook ID/URL Prefix in the Facebook developer app.
Edit: Your issue is probably that the access_token is expiring so it's have to re-ask for permissions.
This will happen if your application did not request offline_access permissions. In the newer SDK offline_access is deprecated and you now have to extend the access_token.
See this link: https://developers.facebook.com/docs/mobile/ios/build/#extend_token
As this Question is already answered , but i would like to add another helpful answer for Swift 3.0 :
While using FB Login in Swift , i having issue and i previously did this way:
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.loginBehavior = .systemAccount
As this uses , System account to check user is authorized for login or not . Unless you logout and login through different user , application shows same "Already authorized" message in place of Fresh login . So i used this way and this trick does the work :
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.loginBehavior = .web.
This show Login Screen after logout.
Hope this helps to solve this issue.
Feel free to comment . Thanks.
You should check if there is a current session before logging in with FBSDKLoginManager. Do not use [loginManager logout] before logging in.
if ([FBSDKAccessToken currentAccessToken])
{
NSLog(#"Token is available : %#",[[FBSDKAccessToken currentAccessToken]tokenString]);
// Now get details using graphpath.
} else {
// login with permissions using FBSDKLoginManager and get details using graphpath in completion
}
There is a open bug at facebook.com
https://developers.facebook.com/bugs/190389531089978
But the bug only appears at android, ios works fine.
(btw. same behavior in the foursquare and spotify android app - check it out)
Run your iOS FB application into device not simulator it works fine, and didn't shows the already authorized screen.
Thank you.
I'm learning how to integrate facebook api in iphone app.
First I visited facebook website, went to applications->developer and created an app. Noted down private key and secret key.
Now, I'm using FBConnect sample code. I am using my keys in FBConnect app. And I set session proxy as
static NSString* kGetSessionProxy = #"SessionViewController"; // #"<YOUR SESSION CALLBACK)>";
I'm able to run the app and when I click "Connect to Facebook", its asking me for credentials as well. But afte providing credentials, its failing. The following delegate method is being called:
- (void)sessionDidNotLogin:(FBSession*)session { _label.text = #"Canceled login"; }
I'm not understanding why I'm ending up in above delegate.
What are all options that I've to select in facebook website when creating new application?
Please help me.
When I made kGetSessionProxy to nil, it worked without any problem. But I didn't understand why it didn't when i gave some value.
