Facebook authentication doesnot auto closes - facebook

I am trying to integrating Facebook-Connect SDK to a cocos2d-x game on iOS platform.
I am using the api,
[FBSession openActiveSessionWithReadPermissions:nil
allowLoginUI:TRUE
completionHandler:^(FBSession *session, FBSessionState state, NSError *error)
{
if(state == FBSessionStateOpen)
NSLog(#"Success");
}
Dialog box doesn't close on pressing okay, however the completionHandler executes successfully with FBSessionStateOpenstate.

I see you tagged this question iOS 6 so I'm assuming you are developing this game for iOS 6 devices which you'll be able to use iOS 6 integration with Facebook.
I explained how i did it once (https://stackoverflow.com/a/14151853/1449151) but I put it here anyway. If you like to use iOS 6 Facebook integration you could follow these steps to make sure you did all of them right. (for instance I see your permission is nil, see how i did it below). Hope it helps:
OK here is how I do this integration with iOS 6 and get what I want from Facebook:
In AppDelegate I do this:
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
return [FBSession.activeSession handleOpenURL:url];
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
[FBSession.activeSession handleDidBecomeActive];
}
- (void)applicationWillTerminate:(UIApplication *)application
{
[FBSession.activeSession close];
}
and in my ViewController where I want to retrieve information about myself or my friends I do this (NOTE: this is a test, so it is a lot of permissions!):
NSArray *permissions =
[NSArray arrayWithObjects:#"email", #"user_location",
#"user_birthday",
#"user_likes", #"user_interests",#"friends_interests",#"friends_birthday",#"friends_location",#"friends_hometown",#"friends_photos",#"friends_status",
#"friends_about_me", #"friends_birthday", #"friends_hometown", #"friends_interests", #"friends_likes", #"friends_location", nil];
[FBSession openActiveSessionWithReadPermissions:permissions
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
/* handle success + failure in block */
if (status) {
NSLog(#"Facebook Read Permission is successful!");
[self presentPostOptions];
// [self presentPostOptions];
}
}];
Then in "presentPostOptions" I do this (in this example I try to retrieve something from my friend):
- (void)presentPostOptions
{
[[FBRequest requestForMyFriends] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error)
{
if (!error) {
NSArray *data = [user objectForKey:#"data"];
NSLog(#"%d", [data count]);
for (FBGraphObject<FBGraphUser> *friend in data) {
NSLog(#"%#", [friend first_name]);
NSLog(#"%#", [friend last_name]);
NSLog(#"%#", [friend id]);
//make sure you have FBProfilePictureView outlet in your view
//otherwise skip the profile picture!
self.fbProfilePic.profileID = #"you'r friend's profile.id";
}
}
else
{
NSLog(#"error");
// [self didFailWithError:error];
}
}];
I don't know what else you want to do because in your question you just tried to make a connection but this way you can do what ever you want while you are integrated in iOS 6.
One more thing, make sure about your App Settings over Facebook and the configs over there like enable your app for iOS and the ID for iPhone/iPad. Also the FacebookAppID in your plist.
Let me know if it works out for you,
EDIT: My Facebook SDK is 3.1.1 btw.

how to check if already logged in Facebook in ios?

I am using "Graph Api" For Facebook login with in my app. I successfully logIn and logged out with this code
facebook = [[Facebook alloc] initWithAppId:kAppId andDelegate:self.viewController];
and i using below code for already facebook logged in
if (![facebook isSessionValid]) {
[facebook authorize:permissions ];
}
My problem is i install Facebook App, and i logged in via Facebook App. then i run my app, it ask again login Facebook. how i solve this issue. it should take as a default FB app login credentials. i saw many app using this feature. anyone know the solution
1. In your AppDelegate.m file
define NSString *const FBSessionStateChangedNotification =
#"com.example:FBSessionStateChangedNotification";
replace com.example with your bundle identifier name
2.- In method
(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[FBSession setActiveSession:[FBSession new]];
if ([FBSession activeSession].state == FBSessionStateCreatedTokenLoaded)
{
// means u are already logged in
//do ur code
[self openSessionWithAllowLoginUI:NO];
}
else
{ //do ur code
[self openSessionWithAllowLoginUI:YES];
}
}
3. whenenever and wherever this method is called after end of switch case write
- (void)sessionStateChanged:(FBSession *)session
state:(FBSessionState) state
error:(NSError *)error
{
[[NSNotificationCenter defaultCenter]
postNotificationName:FBSessionStateChangedNotification
object:session];
}
- (BOOL)openSessionWithAllowLoginUI:(BOOL)allowLoginUI
{
return [FBSession openActiveSessionWithReadPermissions:#"email"
allowLoginUI:allowLoginUI
completionHandler:^(FBSession *session, FBSessionState state, NSError *error)
{
[self sessionStateChanged:session state:state error:error];
}];
}
Sorry in your appDelegate.h file it should be
extern NSString *const FBSessionStateChangedNotification;

iOS native Facebook Login fails for Mobile Safari authentication

I have a native iOS app with Facebook Login integrated. The login flow works when the native Facebook app is installed.
However, when I delete the app, the FB login fallback on FB Mobile Safari webapp. The app switching works fine, but when controls come back to my app, the state of the session is declared FBSessionStateClosedLoginFailed.
I am using Facebook SDK v3.5.2 as of June 6th, 2013
Using iPad1 iOS5.1.1
/*
* Opens a Facebook session and optionally shows the login UX.
*/
- (BOOL)openSessionWithAllowLoginUI:(BOOL)allowLoginUI {
NSArray *permissions = [[NSArray alloc] initWithObjects:
#"email",
#"publish_actions",
nil];
BOOL result = NO;
FBSession *session =
[[FBSession alloc] initWithAppID:nil
permissions:permissions
urlSchemeSuffix:#"<MySchemeSuffix>"
tokenCacheStrategy:nil];
if (allowLoginUI ||
(session.state == FBSessionStateCreatedTokenLoaded)) {
[FBSession setActiveSession:session];
[session openWithBehavior:FBSessionLoginBehaviorWithFallbackToWebView
completionHandler:
^(FBSession *session, FBSessionState state, NSError *error)
{
[self sessionStateChanged:session state:state error:error];
}];
result = session.isOpen;
}
return result;
}
/*
* If we have a valid session at the time of openURL call, we handle
* Facebook transitions by passing the url argument to handleOpenURL
*/
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
// attempt to extract a token from the url
//return [FBSession.activeSession handleOpenURL:url];
BOOL urlWasHandled = [FBAppCall handleOpenURL:url
sourceApplication:sourceApplication
fallbackHandler:^(FBAppCall *call) {
// handle deep links and responses for Login or Share Dialog here
}];
return urlWasHandled;
}
/*
* Callback for session changes.
*/
- (void)sessionStateChanged:(FBSession *)session
state:(FBSessionState) state
error:(NSError *)error
{
switch (state) {
case FBSessionStateOpen:
if (!error) {
if (FBSession.activeSession.isOpen) {
[[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
//Application specific code goes here.
}
}];
}
// We have a valid session
NSLog(#"User session found");
}
break;
case FBSessionStateClosed:
case FBSessionStateClosedLoginFailed:
[FBSession.activeSession closeAndClearTokenInformation];
break;
default:
break;
}
}
I happened to fix the issue.
The bug was, I was requesting read and write permissions in the same call.
Taking out the "publish_actions" from permissions solved the issue.
I tested Facebook Login in iOS6+ through native FB login, native FB app, and webapp.
Also tested on iOS5.1.1 through native FB app, and webapp.

The operation couldn't be completed.(com.facebook.sdk error 2.) error iOS 6 [duplicate]

I'm using die Facebook SDK 3.1.1 to implement FB Connect in my iOS application. This works fine in the simple case with either the new FB integration (logged in on iOS) or falling back to the normal authorization via web view (I do not have the native Facebook application installed in both cases).
The problem occurs when I switch the account on iOS level. Logging out and logging in with a different FB user account.
To log in/authorize I perform:
[FBSession openActiveSessionWithReadPermissions:nil allowLoginUI:allowLoginUI
completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
[self sessionStateChanged:session state:state error:error];
}];
If then get a FBSessionStateClosedLoginFailed every time even though I perform a closeAndClearTokenInformation when that state is reached:
- (void)sessionStateChanged:(FBSession *)session
state:(FBSessionState) state
error:(NSError *)error
{
NSLog(#"Session State Changed: %u", [[FBSession activeSession] state]);
switch (state) {
case FBSessionStateOpen:
break;
case FBSessionStateClosed:
case FBSessionStateClosedLoginFailed:
NSLog(#"FBSessionStateClosedLoginFailed ERROR: %#", [error description]);
[[FBSession activeSession] closeAndClearTokenInformation];
break;
default:
break;
}
However, I receive the same state on every retry. My log says the following:
FBSDKLog: FBSession **INVALID** transition from FBSessionStateCreated to FBSessionStateClosed
FBSDKLog: FBSession transition from FBSessionStateCreated to FBSessionStateCreatedOpening
FBSDKLog: FBSession transition from FBSessionStateCreatedOpening to FBSessionStateClosedLoginFailed Session State Changed: 257
FBSessionStateClosedLoginFailed TOKEN: (null)
FBSessionStateClosedLoginFailed ERROR: Error Domain=com.facebook.sdk Code=2 "The operation couldn’t be completed. (com.facebook.sdk error 2.)" UserInfo=0xb24cc20 {com.facebook.sdk:ErrorLoginFailedReason=com.facebook.sdk:ErrorLoginFailedReason}
Can anyone reproduce this or has any idea where the problem might lie?
Another answer gives a way to manually resync the device with the server. I defined a method called fbRsync to call this code. Make sure to #import <Accounts/Accounts.h> in your implementation file and then define this method:
-(void)fbResync
{
ACAccountStore *accountStore;
ACAccountType *accountTypeFB;
if ((accountStore = [[ACAccountStore alloc] init]) && (accountTypeFB = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook] ) ){
NSArray *fbAccounts = [accountStore accountsWithAccountType:accountTypeFB];
id account;
if (fbAccounts && [fbAccounts count] > 0 && (account = [fbAccounts objectAtIndex:0])){
[accountStore renewCredentialsForAccount:account completion:^(ACAccountCredentialRenewResult renewResult, NSError *error) {
//we don't actually need to inspect renewResult or error.
if (error){
}
}];
}
}
I then call fbResync if openActiveSessionWithReadPermissions yields an error:
[FBSession openActiveSessionWithReadPermissions:permissions
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
if(error)
{
NSLog(#"Session error");
[self fbResync];
[NSThread sleepForTimeInterval:0.5]; //half a second
[FBSession openActiveSessionWithReadPermissions:permissions
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
[self sessionStateChanged:session state:state error:error];
}];
}
else
[self sessionStateChanged:session state:state error:error];
}];
The half a second delay is likely unnecessary, but it currently gives me piece of mind.
This seems to solve the problem for me. I can now switch between Facebook accounts and am able to log in. Yay!
I had the same problem. Check that your FB App is enabled in Settings -> Facebook.
Mine was disabled (even though I don't remember disabling it) and once I enabled it, it was fixed.
In my test process, I've added and removed my FB App several times from my FB Account, which is linked with my iPhone. It may explain why, magically, my app was disabled.
In ios 6 with fb sdk 3.1.1. Please pass permissions param as "nil or email" in "[FBSessio openActiveSessionWithReadPermissions..." method. Here my code it was works great.
#define IOS_NEWER_OR_EQUAL_TO_6 ( [ [ [ UIDevice currentDevice ] systemVersion ] floatValue ] >= 6.0 )
-(void)showFBLogin
{
[FBSession.activeSession closeAndClearTokenInformation];
NSArray *permissions = [NSArray arrayWithObjects:#"email, publish_actions, publish_stream", nil];
#ifdef IOS_NEWER_OR_EQUAL_TO_6
permissions = nil; or NSArray *permissions = [NSArray arrayWithObjects:#"email",nil];
#endif
NSLog(#"\npermissions = %#", permissions);
[FBSession openActiveSessionWithReadPermissions:permissions
allowLoginUI:YES
completionHandler:
^(FBSession *session,
FBSessionState state, NSError *error) {
NSLog(#"\nfb sdk error = %#", error);
switch (state) {
case FBSessionStateOpen:
[[FBRequest requestForMe] startWithCompletionHandler:
^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
if (!error) {
//success
}
}];
break;
case FBSessionStateClosed:
//need to handle
break;
case FBSessionStateClosedLoginFailed:
//need to handle
break;
default:
break;
}
}];
}
I have the same problem on 3.1.3 FB SDK with iOS7.1. And I find a solution here. Hope it help!!
I have tried all answers here.
#loganathan nil permissions, #ill_always_be_a_warriors fbResync.
All of those don't work for me.
But I found it will works well when I launch the same code in iPhone 7.1 simulator
(without SSO"Single Sign On")
The same code works well on old version iOS FB SDK(not sure which version, but not 3.13)
(but no SSO will show when try to login)
So, I try to re-write a sample problem. I found several different here.
1. https://developers.facebook.com/docs/ios/getting-started Add new FacebookDisplayName
2. I modify my BundleID for iTune connect but I am not update it back to Faceboook App Dev
After modify those setting, it works on my iOS app with SSO feature.
Hope it help!!
Did you Try the RenewSystemCredential Methods? Take a look at this post:
Facebook iOS SDK extendAccessToken not Working - fbDidExtendToken not being called
I got the same error. But i used #ill_always_be_a_warriors method: -(void)fbResync but not work for me.
I finally found it's my permissions issue, i removed offline_access permission, it works, hope it helps some one.

Fetch cached access token through FBSession using Facebook SDK

Is there a way to fetch cached access token through FBSession using Facebook SDK if the user is logged in native Facebook.
I am trying to implement autologin through Facebook in an app i.e.when a user is logged in native Facebook then the app should not ask for the login and user should get automatically logged in.
I have used FBSession and FBTokenCacheStrategy and the user is getting logged in automatically but I am not able to fetch the access token which I need to call some API. The following code I am using to get this done :
CacheToken = [[FBTokenCache alloc]init];
NSArray *permissions = [[NSArray alloc]initWithObjects:#"email,user_photos,user_videos,publish_stream,offline_access,user_checkins,friends_checkins", nil];
self.fbsession = [[FBSession alloc] initWithAppID:#"484473011575776"
permissions:permissions
urlSchemeSuffix:nil
tokenCacheStrategy:CacheToken];
(fbsession is the object of Facebook SDK class FBSession)
[FBSession setActiveSession:self.fbsession];
[FBSession openActiveSessionWithReadPermissions:permissions
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
[self sessionStateChanged:session state:state error:error];
Thanks in advance.
To get the access token you should use this:
[FBSession activeSession] accessToken]
However, it seems like you want to check whether there is already a (cached) access token. To do this you can do this:
// See if we have a valid token for the current state.
if (FBSession.activeSession.state == FBSessionStateCreatedTokenLoaded) {
NSLog(#"The value access token is: %#", [[FBSession activeSession] accessToken]);
} else {
// No, display the login page.
}
Make sure also to do this in your app delegate or the access token will be nil:
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
return [FBSession.activeSession handleOpenURL:url];
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
// We need to properly handle activation of the application with regards to Facebook Login
// (e.g., returning from iOS 6.0 Login Dialog or from fast app switching).
[FBSession.activeSession handleDidBecomeActive];
}
Hope this helps
Try following code..
if (FBSession.activeSession.isOpen)
{
NSString *token = [[[FBSession activeSession] accessTokenData] accessToken];
}
hope this will work out for you..

FBSession often fails to be at FBSessionStateCreatedTokenLoaded when returning to foreground

I am using Facebook iOS SDK3.0 (client is not ready to move to 3.1 yet), and have been having trouble to get FBSession to be at the FBSessionStateCreatedTokenLoaded when the app returns to the foreground after a longer period of time (close to a day); I don't have issue if I just send the app to background and come back to the foreground after a minute or two
my code is as follow, please let me know if I should provide further information; I have this issues across devices (4, 4S, 5) and iOS version (4.3, 5.0, 5.1, 6.0)
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
if (![self openSessionWithAllowLoginUI:NO]) {
// still allow loading the public feed even though user is not logged in (the view controller will have a login button overlay)
[[self pictureFeedVC] loadFeed];
}
...
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
DEBUGLog(#"didBecomeActive");
DEBUGLog(#"FBSession is Open? %#",FBSession.activeSession.isOpen ? #"YES" : #"NO");
if (FBSession.activeSession.state == FBSessionStateCreatedOpening) {
//Dismiss login view controller
if ([self.tabBarController modalViewController]) {
[self.tabBarController dismissModalViewControllerAnimated:NO];
}
[FBSession.activeSession close];
}
}
- (BOOL)openSessionWithAllowLoginUI:(BOOL)allowLoginUI {
BOOL result = NO;
[FBSettings setLoggingBehavior:[NSSet setWithObjects:FBLoggingBehaviorSessionStateTransitions,nil]];
NSArray *permissions = [NSArray arrayWithObjects:#"publish_actions", #"email", nil];
FBSession *session = [[FBSession alloc] initWithAppID:nil permissions:permissions urlSchemeSuffix:FB_URL_SCHEME_SUFFIX tokenCacheStrategy:nil];
if (allowLoginUI || (session.state == FBSessionStateCreatedTokenLoaded)) {
[FBSession setActiveSession:session];
[session openWithCompletionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
[self sessionStateChanged:session state:state error:error];
}];
result = session.isOpen;
}
return result;
}
- (void)sessionStateChanged:(FBSession *)session state:(FBSessionState)state error:(NSError *)error
{
DEBUGLog(#"changed FB state");
switch (state) {
case FBSessionStateOpen:
if (!error) {
DEBUGLog(#"FBSessionStateOpen");
[[self pictureFeedVC] loadFeed];
}
break;
case FBSessionStateClosed:
DEBUGLog(#"FBSessionStateClosed");
case FBSessionStateClosedLoginFailed:
DEBUGLog(#"FBSessionStateClosedLoginFailed");
[session closeAndClearTokenInformation];
[self.tabBarController showFBLoginView];
break;
default:
break;
}
}
I am having problem where after extended period in the background, the DEBUGLog(#"FBSession is Open? %#",FBSession.activeSession.isOpen ? #"YES" : #"NO"); in applicationDidBecomeActive: will print a NO
more info: this app relies on Facebook login entirely, it uses facebook user ID to identify users, therefore for lots of actions I need to pass the Facebook access token so that the server can get the facebook user ID even though a lot of times those actions does not require api calls to facebook (besides getting the user ID from the access token of course). My other question is whether I need to actively do something to refresh the token or do something keep the FBSession open (if so, how?), would that be the reason why the FBSession.activeSession might not be in an open state when I return to foreground?
Thanks much in advance!
