When I use following code to open FBWebDialog, Once FBWebDialog is open click in username textfield and keyboard is displayed now if you rotate iPad device, FBWebDialog is not auto-rotating to landscape orientation.
[FBSession setActiveSession: [[FBSession alloc] initWithPermissions:permission] ];
[[FBSession activeSession] openWithBehavior:FBSessionLoginBehaviorForcingWebView completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
switch (status) {
case FBSessionStateOpen:
[self getMyData];
break;
case FBSessionStateClosedLoginFailed: {
NSString *errorCode = [[error userInfo] objectForKey:FBErrorLoginFailedOriginalErrorCode];
NSString *errorReason = [[error userInfo] objectForKey:FBErrorLoginFailedReason];
BOOL userDidCancel = !errorCode && (!errorReason || [errorReason isEqualToString:FBErrorLoginFailedReasonInlineCancelledValue]);
if(error.code == 2 && ![errorReason isEqualToString:#"com.facebook.sdk:UserLoginCancelled"]) {
UIAlertView *errorMessage = [[UIAlertView alloc] initWithTitle:kFBAlertTitle message:kFBAuthenticationErrorMessage delegate:nil cancelButtonTitle:kOk otherButtonTitles:nil];
[errorMessage performSelectorOnMainThread:#selector(show) withObject:nil waitUntilDone:YES];
errorMessage = nil;
}
}
break;
// presently extension, log-out and invalidation are being implemented in the Facebook class
default:
break; // so we do nothing in response to those state transitions
}
}];
Following are steps to reproduce this issue :
Open FBWebialog which opens inside iPad app
Click in username textfield and keyboard is displayed
Now if you rotate iPad device, FBWebDialog is not auto-rotating to landscape orientation.
Please help me to solve this issue....
Its bug from facebook side, here is the my query posted to the facbook support team. Even not getting any kind of response from Facebook,its ridicules...

My app will be used by multiple users.
How can I integrate facebook in a way so that the safari doesn't save any user credentials & throw a login page each time some one tries to login.
I already used FBSessionLoginBehaviorForcingWebView to force a web view login within the app but the problem is, when the first user tries to login to fb via the view presented within the app, the control then goes to safari for authentication & it just saves the creds.
So when other user tries to log in, & enters his credentials in the app local UIWebView, the control again goes to safari, which already has previos creds stored & the new user just cannot authenticate.
So basically the first user is permanently logged in. Clearing the cookies for web view doesn't work. I cant clear them for safari.
Help
Thanks in advance.
This is what I have been doing
if([FBSession activeSession].isOpen)
{
[[FBSession activeSession] closeAndClearTokenInformation];//Also, clearing all the local cookies
}
else
{
AppDelegate *delegate = [UIApplication sharedApplication].delegate;
delegate.session = [[FBSession alloc] init];
[FBSession setActiveSession:delegate.session];
[delegate.session openWithBehavior:FBSessionLoginBehaviorForcingWebView completionHandler:^(FBSession *session1, FBSessionState status, NSError *error) {
if (!error) {
[self openSession]; // your method
}
}];
}
- (void)sessionStateChanged:(FBSession *)session state:(FBSessionState) state error:(NSError *)error{
switch (state) {
case FBSessionStateOpen:
{
[FBRequestConnection startForPostStatusUpdate:#"Some message"completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if (!error) {
//logout again
NSLog(#"startForPostStatusUpdate SUCESS");
}
else {
//logout again
NSLog(#"startForPostStatusUpdate FAIL");
}
}];
}
break;
case FBSessionStateClosed:
{
NSLog(#"FBSessionStateClosed");
}
break;
case FBSessionStateClosedLoginFailed:
[FBSession.activeSession closeAndClearTokenInformation];
break;
default:
break;
}
if (error) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Error" message:error.localizedDescription delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
}
}
Also, modified the app delegate with your methods.
Found a solution. Basically, calling the following:
[FBSession.activeSession closeAndClearTokenInformation];
[FBSession.activeSession close];
[FBSession setActiveSession:nil];
Only clears the local FB session information but not the Safari cookies. So, after I log in the user, I clear the Safari cookies:
NSHTTPCookie *cookie;
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [storage cookies]) {
[storage deleteCookie:cookie];
}
[[NSUserDefaults standardUserDefaults] synchronize];
It isn't very elegant, but it works. Now, when the next user tries to log in, it forces them to enter their credentials.
You just need to use this method after you want to close the FB Session.
[FBSession.activeSession closeAndClearTokenInformation];
This will clear the Facebook Token, and whenever button will be pressed for Facebook share, it will ask for new token credential and it will show Facebook login view again.
Use following code in AppDelegate
// This method will handle facebook session.
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation
{
// Facebook SDK * login flow *
// Attempt to handle URLs to complete any auth (e.g., SSO) flow.
return [FBAppCall handleOpenURL:url sourceApplication:sourceApplication fallbackHandler:^(FBAppCall *call) {
// Facebook SDK * App Linking *
// For simplicity, this sample will ignore the link if the session is already
// open but a more advanced app could support features like user switching.
if (call.accessTokenData) {
if ([FBSession activeSession].isOpen) {
NSLog(#"INFO: Ignoring app link because current session is open.");
}
else {
[self handleAppLink:call.accessTokenData];
}
}
}];
}
// Helper method to wrap logic for handling app links.
- (void)handleAppLink:(FBAccessTokenData *)appLinkToken {
// Initialize a new blank session instance...
FBSession *appLinkSession = [[FBSession alloc] initWithAppID:nil
permissions:nil
defaultAudience:FBSessionDefaultAudienceNone
urlSchemeSuffix:nil
tokenCacheStrategy:[FBSessionTokenCachingStrategy nullCacheInstance] ];
[FBSession setActiveSession:appLinkSession];
// ... and open it from the App Link's Token.
[appLinkSession openFromAccessTokenData:appLinkToken
completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
// Forward any errors to the FBLoginView delegate.
if (error) {
//TODO: Show error here
}
}];
}
Add following code where you are opening session for Facebook
/***********************************************************************
This method opens browser or App Url to FB authentication and change FB
session state
************************************************************************/
- (void)openSession
{
NSArray *permisssions = [[NSArray alloc] initWithObjects:#"email",#"user_photos",nil];
[FBSession openActiveSessionWithReadPermissions:permisssions
allowLoginUI:YES
completionHandler:
^(FBSession *session,
FBSessionState state, NSError *error) {
[self sessionStateChanged:session state:state error:error];
}];
}
/***********************************************************************
This method will be called whenever FB Session state changed
It also shows an error message if any error occurs
************************************************************************/
- (void)sessionStateChanged:(FBSession *)session
state:(FBSessionState) state
error:(NSError *)error
{
switch (state) {
case FBSessionStateOpen: {
NSLog(#"FBSession Open State");
//Enter your code what you want to perform when session is open
}
break;
case FBSessionStateClosed:
case FBSessionStateClosedLoginFailed:
// Once the user has logged in, we want them to
// be looking at the root view.
NSLog(#"FBSession State Closed");
[FBSession.activeSession closeAndClearTokenInformation];
[FBSession.activeSession close];
[FBSession setActiveSession:nil];
break;
default:
break;
}
if (error) {
UIAlertView *alertView = [[UIAlertView alloc]
initWithTitle:#"Error"
message:error.localizedDescription
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertView show];
}
}
Now when ever user tap on Facebook Share button check that session exists or not. If not then call openSession method. It will open facebook login view.
There is a sample in the Facebook Github repository, showing how to switch between multiple users.
It looks like it requires use of the custom login flow.
I'm following these two tutorials in Facebook developer website
https://developers.facebook.com/docs/tutorials/ios-sdk-games/requests/
https://developers.facebook.com/docs/howtos/send-requests-using-ios-sdk/#step2
These are my codes:
[FBWebDialogs presentRequestsDialogModallyWithSession:nil
message:[NSString stringWithFormat:#"I just smashed %u friends! Can you beat it?", score]
title: nil
parameters:params
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error)
{
if (error)
{
// Case A: Error launching the dialog or sending request.
UIAlertView* alert = [[UIAlertView alloc] initWithTitle: #"Facebook" message: error.description delegate: nil cancelButtonTitle: #"Ok" otherButtonTitles: nil];
[alert show];
[alert release];
}
else
{
if (result == (FBWebDialogResultDialogCompleted))
{
// Handle the publish feed callback
NSDictionary *urlParams = [self parseURLParams:[resultURL query]];
if ([urlParams valueForKey: #"request"])
{
// User clicked the Share button
NSLog(#"Send");
}
}
}
}];
Problem is after I send out the request, my friend told me that he doesn't receive any notification/request in FB Notification Center site. Does anyone know why?
These are the things I've done:
I've setup properly in info.plist and the Facebook App.
I'm not using Sandbox mode.
My current application is able to log in and post to wall.
I've publish_actions permission.
I did not received any error or warning.
I found my solution here:
Facebook App Requests aren't shown on iOS devices?
It is because I didn't set the iPhone App ID and iPad App ID
Use following method, it will help you :
-(void)openFacebookAuthentication
{
NSArray *permission = [NSArray arrayWithObjects:kFBEmailPermission,kFBUserPhotosPermission, nil];
FBSession *session = [[FBSession alloc] initWithPermissions:permission];
[FBSession setActiveSession: [[FBSession alloc] initWithPermissions:permission] ];
[[FBSession activeSession] openWithBehavior:FBSessionLoginBehaviorForcingWebView completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
switch (status) {
case FBSessionStateOpen:
[self getMyData];
break;
case FBSessionStateClosedLoginFailed: {
// prefer to keep decls near to their use
// unpack the error code and reason in order to compute cancel bool
NSString *errorCode = [[error userInfo] objectForKey:FBErrorLoginFailedOriginalErrorCode];
NSString *errorReason = [[error userInfo] objectForKey:FBErrorLoginFailedReason];
BOOL userDidCancel = !errorCode && (!errorReason || [errorReason isEqualToString:FBErrorLoginFailedReasonInlineCancelledValue]);
//Added by Rigel Networks July 2, 2013 to solve Facebook Cancel button popup issue
if(error.code == 2 && ![errorReason isEqualToString:#"com.facebook.sdk:UserLoginCancelled"]) {
UIAlertView *errorMessage = [[UIAlertView alloc] initWithTitle:kFBAlertTitle
message:kFBAuthenticationErrorMessage
delegate:nil
cancelButtonTitle:kOk
otherButtonTitles:nil];
[errorMessage performSelectorOnMainThread:#selector(show) withObject:nil waitUntilDone:YES];
errorMessage = nil;
}
}
break;
// presently extension, log-out and invalidation are being implemented in the Facebook class
default:
break; // so we do nothing in response to those state transitions
}
}];
permission = nil;
}
I am still using XCode 4.3.2 and iOS 5.1 base SDK. What I want to achieve is to integrate Facebook API for iOS 5.0+ devices. Just basic features such as posting on behalf and getting basic user information.
I am assuming that which ever Facebook SDK works on iOS 5, will work on iOS 6, but I am not sure about that.
As a rookie on Facebook Integration, can anybody shed some light on this issue. ( Since I am working on the project, upgrading the XCode and the iOS SDK is not an option)
Which iOS SDK should I be looking into?
Can I support both iOS 5 and
6, with base SDK 5.1 and XCode 4.3?
Is there an API supporting both iOS versions?
Any musts for Facebook Integration?
First of all you read this article published from Facebook developers
http://developers.facebook.com/docs/getting-started/facebook-sdk-for-ios/
in step 1 it will also work for xcode 4.3
you carefully read all steps one by one n implement
In step6 you write code as follow on where Facebook Btn Pressed
- (IBAction)facebookBtnPressed:(id)sender
{
// if it is available to us, we will post using the native dialog
BOOL displayedNativeDialog = [FBNativeDialogs presentShareDialogModallyFrom:self
initialText:[NSString stringWithFormat:#"Here U write code which u want to post on facebook"]
image:[UIImage imageNamed:#"1.jpg"]
url:[NSURL URLWithString:#""]
handler:nil];
if (!displayedNativeDialog)
{
NSString *shareStr = [NSString stringWithFormat:#"Here U write code which u want to post on facebook"];
NSMutableDictionary* params = [[NSMutableDictionary alloc] initWithObjectsAndKeys:
shareStr,#"description",
#"sharelink", #"link",
#"ImageName", #"picture",
nil];
[self performPublishAction:^{
[FBRequestConnection startWithGraphPath:#"me/feed" parameters:params HTTPMethod:#"POST" completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if (error)
{
NSLog(#"error in post");
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Success" message:#"Post Successfully" delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert show];
}
}];
}];
}
//}
//===set delagate in Viewcontroller.h of mySLComposerSheet
[mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
NSString *output;
switch (result) {
case SLComposeViewControllerResultCancelled:
output = #"Action Cancelled";
break;
case SLComposeViewControllerResultDone:
output = #"Post Successfully";
break;
default:
break;
} //check if everything worked properly. Give out a message on the state.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Facebook" message:output delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert show];
}];
}
- (void) performPublishAction:(void (^)(void)) action {
if ([[FBSession activeSession]isOpen]) {
/*
* if the current session has no publish permission we need to reauthorize
*/
if ([[[FBSession activeSession]permissions]indexOfObject:#"publish_actions"] == NSNotFound) {
[[FBSession activeSession] reauthorizeWithPublishPermissions:[NSArray arrayWithObject:#"publish_actions"]
defaultAudience:FBSessionDefaultAudienceOnlyMe
completionHandler:^(FBSession *session, NSError *error) {
action();
}];
}else{
action();
}
}else{
/*
* open a new session with publish permission
*/
[FBSession openActiveSessionWithPublishPermissions:[NSArray arrayWithObject:#"publish_actions"]
defaultAudience:FBSessionDefaultAudienceOnlyMe
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
if (!error && status == FBSessionStateOpen) {
action();
}else{
NSLog(#"error");
}
}];
}
}
- (void)authorize:(NSArray *)permissions {
self.permissions = permissions;
[self authorizeWithFBAppAuth:NO safariAuth:NO];
}
Ok, the above code is what I am trying to implement. But this code is giving me two errors. The first one is property permission not found in Facebook and second one is instance authorize authorizeWithFBAppAuth: not found.This is share kit 2.0 so maybe this will not work on it, but I need to stop the Facebook app popping up. P.S. I am a Sharekit noob.
- (void)authorize:(NSArray *)permissions {
// if we already have a session, git rid of it
[self.session close];
self.session = nil;
[self.tokenCaching clearToken];
self.session = [[[FBSession alloc] initWithAppID:_appId
permissions:permissions
urlSchemeSuffix:_urlSchemeSuffix
tokenCacheStrategy:self.tokenCaching]
autorelease];
[self.session openWithCompletionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
switch (status) {
case FBSessionStateOpen:
// call the legacy session delegate
[self fbDialogLogin:session.accessToken expirationDate:session.expirationDate];
break;
case FBSessionStateClosedLoginFailed:
{ // prefer to keep decls near to their use
// unpack the error code and reason in order to compute cancel bool
NSString *errorCode = [[error userInfo] objectForKey:FBErrorLoginFailedOriginalErrorCode];
NSString *errorReason = [[error userInfo] objectForKey:FBErrorLoginFailedReason];
BOOL userDidCancel = !errorCode && (!errorReason ||
[errorReason isEqualToString:FBErrorLoginFailedReasonInlineCancelledValue]);
// call the legacy session delegate
[self fbDialogNotLogin:userDidCancel];
}
break;
// presently extension, log-out and invalidation are being implemented in the Facebook class
default:
break; // so we do nothing in response to those state transitions
}
}];
}
This code above is the original that came with share kit 2.0, if there is a way to stop Facebook app popping up in the above code please let me know.
Use like below:
- (void)authorize:(NSArray *)permissions
{
self.permissions = permissions;
[self authorizeWithFBAppAuth:NO safariAuth:YES];
}
And then check.
In my application I need user to sign in to Facebook, get friend list in my table view and Post on feeds, but I don't want to redirect the user anywhere. so I used -openWithBehavior:completionHandler: ... Here is my code.
-(IBAction)loginAction:(id)sender {
[self deleteCookies];
// get the app delegate so that we can access the session property
DLAppDelegate *appDelegate = [[UIApplication sharedApplication]delegate];
// this button's job is to flip-flop the session from open to closed
if (appDelegate.session.isOpen) {
// if a user logs out explicitly, we delete any cached token information, and next
// time they run the applicaiton they will be presented with log in UX again; most
// users will simply close the app or switch away, without logging out; this will
// cause the implicit cached-token login to occur on next launch of the application
[appDelegate.session closeAndClearTokenInformation];
} else {
if (appDelegate.session.state != FBSessionStateCreated) {
// Create a new, logged out session.
appDelegate.session = [[FBSession alloc] init];
[self updateView];
}
// if the session isn't open, let's open it now and present the login UX to the user
[appDelegate.session openWithBehavior:FBSessionLoginBehaviorForcingWebView completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
switch (status) {
case FBSessionStateOpen:
// call the legacy session delegate
//Now the session is open do corresponding UI changes
{
FBCacheDescriptor *cacheDescriptor = [FBFriendPickerViewController cacheDescriptor];
[cacheDescriptor prefetchAndCacheForSession:session];
[FBSession openActiveSessionWithAllowLoginUI:NO];
[FBSession openActiveSessionWithPublishPermissions:[NSArray arrayWithObjects:#"publish_stream",#"publish_actions", nil] defaultAudience:FBSessionDefaultAudienceFriends allowLoginUI:NO completionHandler:nil];
}
break;
case FBSessionStateClosedLoginFailed:
{ // prefer to keep decls near to their use
// unpack the error code and reason in order to compute cancel bool
// call the legacy session delegate if needed
//[[delegate facebook] fbDialogNotLogin:userDidCancel];
}
break;
// presently extension, log-out and invalidation are being implemented in the Facebook class
default:
break; // so we do nothing in response to those state transitions
}
[self updateView];
}];
}
}
The user is successfully signed in and I can retrieve the friend list by using FQL. The problem is while posting to feeds. I know I need to get publish permissions to do it. But when I uses the following code to post...
- (IBAction)postAction:(id)sender {
DLAppDelegate *appDelegate = [[UIApplication sharedApplication]delegate];
if (appDelegate.session.isOpen) {
[FBSession openActiveSessionWithAllowLoginUI:NO];
NSMutableDictionary *postParams = [[NSMutableDictionary alloc] initWithObjectsAndKeys:
#"https://developers.facebook.com/ios", #"link",
#"https://developers.facebook.com/attachment/iossdk_logo.png", #"picture",
#"Facebook SDK for iOS", #"name",
#"Build great social apps and get more installs.", #"caption",
#"The Facebook SDK for iOS makes it easier and faster to develop Facebook integrated iOS apps.", #"description",
nil];
if ([_postText.text length]>0) {
[postParams setObject:[_postText text] forKey:#"message"];
}
if (([FBSession.activeSession.permissions
indexOfObject:#"publish_actions"] == NSNotFound) ||
([FBSession.activeSession.permissions
indexOfObject:#"publish_stream"] == NSNotFound)) {
// No permissions found in session, ask for it
[FBSession.activeSession
reauthorizeWithPublishPermissions:
[NSArray arrayWithObjects:#"publish_stream",#"publish_actions",nil]
defaultAudience:FBSessionDefaultAudienceFriends
completionHandler:^(FBSession *session, NSError *error) {
if (!error) {
// If permissions granted, publish the story
[self publishStory:postParams];
}
}];
} else {
// If permissions present, publish the story
[self publishStory:postParams];
}
}
}
-(void)publishStory:(NSDictionary *)postParams {
[FBRequestConnection startWithGraphPath:
#"me/feed" parameters:postParams HTTPMethod:#"POST"
completionHandler:^(FBRequestConnection *connection, id result, NSError *error)
{
if (!error) {
//Tell the user that it worked.
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Shared:"
message:[NSString stringWithFormat:#"Sucessfully posted to your wall."]
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
alertView.tag = 101;
[alertView show];
}
else {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Error:"
message:error.localizedDescription
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertView show];
NSLog(#"%#",error);
}
}
];
}
This code redirects the user to Safari or Facebook App. Which I don't want to happen.
Definitely I need to get publish permissions while logging in. the question is HOW?
You have to set FBSessionLoginBehavior, to change it the only way is to use:
[session openWithBehavior:FBSessionLoginBehaviorWithNoFallbackToWebView
completionHandler:^(FBSession *session,
FBSessionState status,
NSError *error) {
// Respond to session state changes,
// ex: updating the view
}];
I see you use FBSessionLoginBehaviorForcingWebView, so to get what you want you have to choose from this enum:
typedef enum {
/*! Attempt Facebook Login, ask user for credentials if necessary */
FBSessionLoginBehaviorWithFallbackToWebView = 0,
/*! Attempt Facebook Login, no direct request for credentials will be made */
FBSessionLoginBehaviorWithNoFallbackToWebView = 1,
/*! Only attempt WebView Login; ask user for credentials */
FBSessionLoginBehaviorForcingWebView = 2,
/*! Attempt Facebook Login, prefering system account and falling back to fast app switch if necessary */
FBSessionLoginBehaviorUseSystemAccountIfPresent = 3,
} FBSessionLoginBehavior;
Now to solve this "Definitely I need to get publish permissions while logging in. the question is HOW?" you may - (id)initWithPermissions:(NSArray*)permissions; your Session :
NSArray *permissions = #[#"publish_stream", #"publish_actions"];
appDelegate.session = [[FBSession alloc] initWithPermissions:permissions];
