facebook-ios-sdk's Introduction

Facebook SDK for iOS

Platforms circleci

CocoaPods Carthage compatible

This open-source library allows you to integrate Facebook into your iOS app.

Learn more about the provided samples, documentation, integrating the SDK into your app, accessing source code, and more at

Please take a moment and subscribe to releases so that you can be notified about new features, deprecations, and critical fixes. To see information about the latest release, consult our changelog.

⚠️ Be Advised ⚠️

We have begun rewriting the iOS SDK in Swift in order to modernize the code base.

Please monitor the changelog for updates to existing interfaces but keep in mind that some interfaces will be unstable during this process. As such, updating to a minor version may introduce compilation issues related to language interoperability. Using symbols now defined in Swift may require using @import syntax from Objective-C and using C++ will likely require workarounds like creating wrappers in Objective-C.

Please bear with us as we work towards providing an improved experience for integrating with the Facebook platform.

facebook-ios-sdk's Issues

publishStream URLs with query strings not working

Am I missing something? When using publishStream I want to include the URL to a specific product that includes a query string as the href for the post to link to, set in the "attachment" NSDictionary with the key "href" in the - (IBAction) publishStream: (id)sender method. It works fine if I use a URL with no query string, but if there is an ampersand in the url it doesn't send any of the data (name, caption, description, or url) to the Facebook post.

The same URL worked fine with the previous version of the Facebook iPhone sdk, and no way of escaping the & seems to work.

Please add Tags

i'm trying to use the facebook-ios-sdk and see that there are no tags specified for a "last known good" or stable release. The benefit of doing this is many..

  1. so that most users are using the same bits in their applications (rather than when they last synced.
  2. Easier to track issues when they are reported (since they would be tied to specific versions)
  3. We don't end up downloading code which may have some bad commit's and in turn sped several hrs debugging a problem.

So.. please add some tags/versions of the ios SDK... Thanks!

Problems uploading pictures to groups

Having some problems uploading photos to groups here. Works fine when I try to upload to the users own album, but using the oid of the group, and trying to upload will just allow the upload to finish, and then return an empty result with no error.

Anybody know what might be causing this?

Logout behaves oddly.

When I log out, then immediately try to log back in, I'll be prompted for my username and password as expected.

If I logout, then quit the app (or send to the background in iOS4) then return to the app and hit login, my old credentials seem to be remembered and I'm logged in without being asked for a password. So logging out doesn't really seem to be working completely.


How i can add photo to some album with specific aid?

In the description of the api method (photos.upload) says that specifying the identifier, I can download the photo into the appropriate album. But, really, photos uploaded to default application album. Tell me, please, what my mistake?)))

ps: sorry for my english, i know it's terrible))

The token can't access to the home feed

Hello, I use iphone facebook sdk to get the token, and then I use graph api(not through the sdk) to request home feed. It gives me:

"error": {
"type": "OAuthException",
"message": "Error processing access token."

However, this is working before, and all other graph api is working fine. Please fix this.

FBConnect does not work on device

I am implementing FBConnect into my application and it works perfectly on simulator. When I try to run it on device, the FBLoginDialog box shows up for a couple of seconds (with a spinner) then closes immediately. When I trace the fail I found that it was immediately failing with an error:

Error Domain=kCFErrorDomainCFNetwork
Code=-1202 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be \\u201d which could put your confidential information at risk."

While investigating on Google I found this may have something to do with SSL certificates but I am unaware on how to resolve it. Any help would be much appreciated.

Restoring sessions not working

Everything is working great when I first run my app (or when I run the Run Around sample app). I can log in and publish to stream.

However, when I close the app, then reopen (having stored the session information in NSUserDefaults as in the Run Around example), then I try to publish to stream, the dialog just displays the message "An error occurred with . Please try again later." (I checked and the session expiration date is a long way off, and all of the session variables seem to have been stored + restored properly).

This happens both in my app and in the Run Around sample app when I close them, storing session info, and then open them again and try to run publishStream. Is there a working way to restore a session that you could give example code for? It's pretty important for my app.


Missing redirect_uri parameter

I forked the repo and built the app fine. Taping the "login" button displays a popup with an error in it

{"error":{"type":"OAuthRedirectURIMismatchException", "message":"Missing redirect_uri parameter."}}

I did simple NSLog's to check the value of kRedirectURL, the object pared with the key "redirect_uri", and it's set to fbconnect://success

What am I missing here?

Getting Friends, OK. Getting Home, Feed, etc, fails!.

Hello. Why using this code?

$friends = json_decode(file_get_contents( ''.$session['access_token']) );

I can get successfully my friends list, and when I use this below:

$feed = json_decode(file_get_contents( ''.$session['access_token']) );

.... Why Do I get the array $feed empty?

I know I have feeds because entering by and clicking in I can get my feeds correctly.

I realised that entering by the access_token parameter is not equal than $session['access_token']. Why?

Sudden change in behavior?

So I've been using this framework to login my user, and then loading UIWebViews to display some of the standard Facebook pages like

This morning this suddenly only works the first time I start the app up. The second time I start up the app the normal webpages redirect me to login.php like if my cookies weren't valid. I even went back to my 1.0.0 release here and I get the exact same behavior there. Now if I clear all my cookies it works perfectly again until I load up the app the second time. Since nothing has changed at my end I have to assume the change is at Facebook's end?

This is my login procedure:

  • (void)socialize
    facebook = [[Facebook alloc] init];

    if(![facebook isSessionValid])
    socializing = YES;
    [self login];

  • (void)login
    NSArray *permissions = [NSArray arrayWithObjects:@"publish_stream", @"create_event", @"rsvp_event", @"manage_pages", @"user_about_me", @"", @"user_activities", @"user_birthday", @"user_education_history", @"user_events", @"user_groups", @"user_hometown", @"user_interests", @"user_likes", @"user_location", @"user_notes", @"user_online_presence", @"user_photo_video_tags", @"user_photos", @"user_relationships", @"user_religion_politics", @"user_status", @"user_videos", @"user_website", @"user_work_history", @"", @"read_stream", @"offline_access", @"friends_about_me", @"friends_activities", @"friends_birthday", @"friends_education_history", @"friends_events", @"friends_groups", @"friends_hometown", @"friends_interests", @"friends_likes", @"friends_location", @"friends_notes", @"friends_online_presence", @"friends_photo_video_tags", @"friends_photos", @"friends_relationships", @"friends_religion_politics", @"friends_status", @"friends_videos", @"friends_website", @"friends_work_history", nil];
    [facebook authorize:appId

Doing normal Graph API calls with the framework works fine, it's just loading the normal webpages that seem to be the problem. So what changed last night?

focus problem when editing the message (in stream.publish)

To reproduce this bug :

Result : I can't type. I need to double-click again into the textfield to make the keyboard work

One thing I noticed, if I put a shorter description it works

dialogDidComplete is called twice

In FBDialog.m line 409 you call
[self dialogDidSucceed:url]; which calls
[self dismissWithSuccess:YES animated:YES]; which in turn calls
[_delegate dialogDidComplete:self];

and in the next line (410) you call
[self dismissWithSuccess:YES animated:YES]; which calls
[_delegate dialogDidComplete:self]; again

Since my app crashed sporadically, I removed line 410 and everything works fine for me since then.

By the way: the same applies to dialogDidNotComplete

Error connecting to graph.facebook

Hi there,

I haven't thoroughly delved into the code yet, but looks like whenever I run both the examples, I get the same json object-error from facebook: "error": {
"type": "OAuthInvalidClientException",
"message": "Missing client_id parameter."

Somehow, the login params are not passed in the main URL ( Is there a quick fix to alleviate the problem? I checked out the latest code from your git repo, but has this bug... I also used the kAppId of a sample facebook app that I created a week ago, but like I said, the params in FBLoginDialog::initWithURL are not passed in the URL. I'll continue debugging your library, but I was wondering if you have a quick fix.

Also, the UnitTesting code breaks, because it doesn't find the main application's window at launch-time (it's null).

Thanks so much!

Upload Video (FB Task #439513)

Because upload video is not yet supported with graph's i was bouncing it off the REST API, as it turns out I ran into the issue that "This method must run on", most likely I assume the new SDK doesnt know or detect which one to use and always uses Is there an easy solution to this? Or am i possibly doing something wrong?

Publish stream problem.


I'm having a problem when trying to publish a stream. The problem occurs when:

  1. Launching theRunAround app, and login in to FB.
  2. On successful login, leave the app.
  3. Login to FB in a browser.
  4. Re-launch theRunAround app.

The session is correctly restored (my friends are displayed), but when I want to add a run, and the FB dialog appears, the dialog shows the following error:

"An error occurred with 'my_app_name' . Please try again later."

I've added FBDialogDelegate's dialog:didFailWithError: method to the sample, and when I click the "ok" button in the FBDialog, the following is printed to xCode's console:

Error Domain=facebookErrDomain Code=110 UserInfo=0x4d58830 "Operation could not be completed. (facebookErrDomain error 110.)"

What can it be? How can I fix this? This is actually happening to me in my own app, but I've also been able to reproduce it in theRunAround app, and that's why, above, I enumerate the steps to reproduce the issue using that sample.

Thanks you very much!

photos.upload & publish_stream perm

I'm uploading photo's along with the publish_stream permission. Photo uploads are working fine, and go to the correct place, however, it is not always posted in the users stream. Sometimes it does, sometimes it does not (on the same facebook user account). I can't seem to find a reason why, any help / suggestions would be appreciated. I will say that using the prior sdk, the photo's would upload and would show in the users stream every time. So, I'm not sure if the problem is with the SDK, my code, etc.

Authorizing & Permissions

NSArray *permissions =  [[NSArray arrayWithObjects: @"read_stream", @"offline_access", @"publish_stream", nil] retain];

[_facebook authorize:kAppId permissions:permissions delegate:self];

Posting Picture

NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
uploadPicture, @"picture", picCaption, @"caption", nil];

 [_facebook requestWithMethodName: @"photos.upload" 
                       andParams: params
                   andHttpMethod: @"POST" 
                     andDelegate: self];

Potential null dereference. According to coding standards in 'Creating and Returning NSError Objects' the parameter 'error' may be null.

Hi, I am building an app using the ios-sdk and when I use xcode's build and analyze, I get the following message in FBRequest.m
"Potential null dereference. According to coding standards in 'Creating and Returning NSError Objects' the parameter 'error' may be null."

Is there something I can do to stop these, or is it safe to ignore them?


Problems request me

Has anything changed recently? It seems doing a request for "me" no longer works and I just get: Error Domain=facebookErrDomain Code=10000 UserInfo=0xc6279d0 "Operation could not be completed. (facebookErrDomain error 10000.)"

Bug in FBRequest

The FBRequest class needs to retain/release the delegate passed in.

Here's a case where it can crash:

  • User code creates a Facebook instance and calls -logout:self
  • Facebook code creates a FBRequest and issues a server call to logout, but it invokes the fbDidLogout delegate immediately (which is another bug, IMHO)
  • when user code gets told logout is done, it correctly releases the Facebook instance
  • server request from FB completes and it tries to invoke the delegate (the FB instance that is now gone) and crashes.

The fix is to retain the delegate passed to the FBRequest object in FBRequest.m

RequestWithGraphPath me returns facebookErrDomain error 10000

Hi all, something in Facebook change overnight. The demo app was working fine with until probably this morning with the simple call:

[facebook requestWithGraphPath:@"me" andDelegate:self];

Now it returns:
facebookErrDomain error 10000 in the didFailWithError method:

  • (void)request:(FBRequest_)request didFailWithError:(NSError_)error{}

This is with the DemoApp that I tested with the latest release and something changed on the facebook end overnight.

Using the link generated by photos.upload to stream.publish

Basically, what I wanted to do was to upload a UIImage and then publish that particular photo to the stream via a FBDialog. The only way I've been able to upload a photo via NSData is to call requestWithMethodAndName:

[_facebook requestWithMethodName: @"photos.upload" 
                       andParams: imgParams 
                   andHttpMethod: @"POST" 
                     andDelegate: self];

From there, the FBRequestDelegate returns an object that gives a link to the album photo. It also generates a thumbnail link to the photo via a FBCDN domain. Afterwards, my plan was to use to generate a UI dialog which calls stream.publish with a media attachment (basically the information that FBRequestDelegate returned):

[_facebook dialog: @"stream.publish" 
        andParams: params
      andDelegate: self];

However, since Facebook does not allow images hosted on their domains (e.g. FBCDN) to be published with streams, I can't actually show the proper image. The reason I opted to use stream.publish was to let the user create a personalized message to be published into their wall. However, since I can't use the FBCDN link, I haven't figured out a way to actually show the image aside from hosting the image off-site which, in my mind, isn't exactly as efficient.

Is there an easier way to approach this issue? Thanks in advance.

cannot git clone the source

when I perform the git clone in macosx, error "the remote end hung up unexpectedly" is reported. Then I tried the git clone http://....... it asks me for a username and password... and I cannot go through that.. Authentication failed.

So, what should I do??

Authentication Issue

This may be a dumb question:
If all that is required for me to authenticate a session with facebook from inside my app is my app id, what prevents someone else from using MY app id in their app? My app id is publicly visible in my app's facebook url ( There used to be a secret or api key required to create a session - or am I missing something?

Can not use a lot of the Graph API

Been testing a few things with this new SDK the last days, and there are several parts of the Graph API that doesn't seem to work. As an example doing:

[facebook requestWithGraphPath:@"app_id/likes"

Just returns an empty dictionary from the server. Replacing app_id with the actual numeric id of the app. Also doing "album_id/photos" returns an empty dictionary.

Am I misunderstanding something, or is there something wrong with this library?


Trying to upload a photo, this code:

NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
img, @"picture",
[facebook requestWithMethodName: @"photos.upload"
andParams: params
andHttpMethod: @"POST"
andDelegate: self];

results in:
"The operation couldn’t be completed. (facebookErrDomain error 1.)"

This code:
NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
img, @"source",
NSString* album = albumid;
album = [album stringByAppendingString:@"/photos"];
[facebook requestWithGraphPath:album andParams:params andHttpMethod:@"POST" andDelegate:self];

results in:
The operation couldn’t be completed. (facebookErrDomain error 10000)

I had this working with the old rest api, but in the new graph api it does not look like working.

Avoding Warning Message in FBDialog.m

Please check if you could add the following code to FBDialog.m to avoid the warning

    _closeButton.font = [UIFont boldSystemFontOfSize:12];

Kind Regards

using the 'since' or 'until' parameter for Graph requests.

Whenever I try to use the since or until parameters I get

Facebook returned an error Error Domain=facebookErrDomain Code=10000 UserInfo=0x4d13860 "Operation could not be completed. (facebookErrDomain error 10000.)"

Anyone have an working example of a graph request that uses the "since/date" or "until/date" in the NSMutableDictionary params?

Cancel button in login

There is no cancel button in the login dailog shown. The login page is very blank with only two textbox and login button.

Possible memory leak in FBRequest?

When you allocate the NSURLConnection in FBRequest.connect (line 271) - you do the following:
_connection = [[[NSURLConnection alloc] initWithRequest:request delegate:self] retain];

But if you call "alloc" you do not need an extra "retain".

I removed that "retain" and it still works.

Message send

Can you help me? I can't understand how to send message (not stream publish with target_id, private message) to some user with API methods and how mark some thread messages "read".

Login Activity Indicator


I've noticed that when a user enters his username and password, and hits the "Login" button, there's no indication as to whether or not the login is performing.

I mean, no activity indicator is showed while the login is occurring. Will it be possible to add one? How could I add a spinner at the precise moment after which the user has hit the "login" button?

I think it's really important to have one there, otherwise it seems like the app is unresponsive, or that the login button for some reason didn't get pressed...


User keep getting connection error

One of my users keep getting connections errors when starting the app and doing a authorize:

Says he gets "error ref. #7.e1d434d.1282759386.0"

He can access, and just fine from Mobile Safari. Any idea what might be causing this?

Pull request protocol?

Hi there, and thanks for releasing the library on github.

I don't seem able to send a pull request to the github user "facebook." I've sent a couple to the user "yujuan"--is this the appropriate way to do it?

album delete request fails

I wish to delete an album, so I use this code ..

NSMutableDictionary*    params  = [NSMutableDictionary dictionaryWithObject:@"delete" forKey:@"method"];
[appDelegate.facebook requestWithGraphPath:[cellDict objectForKey:@"aid"]  andParams:params  andHttpMethod:@"POST"  andDelegate:nil];

Here's the request/response flow ...

2010-08-27 22:17:02.575 ShareOrStare[19975:207] request: <NSMutableURLRequest>
2010-08-27 22:17:03.552 ShareOrStare[19975:207] response: {"error":{"type":"Exception","message":"(#100) Invalid parameter"}}

The album exists and the ID is correct. What is the issue here?

Cancel a request?

I just realized there is no way to cancel a request. As of now I can't dealloc some of my views as long as there is a request that I haven't gotten an answer for. Can you add a cancel method?

error while trying to do login in 3.1.2

i am evaluating the ios sdk in 3.1.2 and i had encounter few difficulties.
i am getting error when trying to perform log in.

the function - (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error { .. }
in FBLoginDialog.m is fired up and the error is :

Error Domain=NSURLErrorDomain Code=-999 UserInfo=0x46e7a80 "Operation could not be completed. (NSURLErrorDomain error -999.)"

any ideas


FB Connect keep giving the connection error on authorize via SSL.

I've plugged in the new Facebook connect iOS sdk and it was working fine before Aug 23. But then whenever I tried to attempt facebook login it gives the connection error as below.

Error Domain=NSURLErrorDomain Code=-1004 "Could not connect to the server." UserInfo=0x8251030 {NSErrorFailingURLStringKey=

I've noticed that it request for authorize on
'' and redirect to '' which throws an exception.

NOTE: I've checked it without HTTPS vesion and it seems to be working fine. Does anyone know why Facebook connect is not working on SSL?

Renewing auth token makes dialog appear and disappear

When a user is logged in but the access token is expired, calling -(void)authorize:permissions:delegate: on the Facebook object causes the FBLoginDialog box to animated on and off the screen instantly. If the renewal can be done without user interaction, it would be a much better experience to let that happen in the background instead of obstructing the application.

Publish stream with long description

When publishing a stream with a long description field (text needs to be past the Skip/Publish buttons), the text extends past the end of the screen and goes behind the Skip/Publish buttons.

When you scroll the view the skip/publish buttons move up and are over the top of the description text instead of being at the bottom of the screen.

DemoApp not functioning under iOS 4.2/simulator

When attempting to login to FB - the first view gives:
{"error":{"type":"OAuthException","message":"Missing redirect_uri parameter."}} in the web view. This is prior to providing login credentials.

Request for @2x images

Is it possible to add the @2x versions of the (currently two) images in the bundle? That would be very helpful. I could create them, but I'm sure Facebook has style guidelines that I don't know about--I'd hate to duplicate the effort. Here's a link for background, but I'm sure you're all over it.


FB login dialog default email


I was wondering if there's a way to set a default email in FB login dialog's textfield.

In the past, calling this code

NSHTTPCookieStorage* cookies = [NSHTTPCookieStorage sharedHTTPCookieStorage];
NSHTTPCookie* testCookie = [NSHTTPCookie cookieWithProperties:
                            [NSDictionary dictionaryWithObjectsAndKeys:
                             [HTTPRequest encodeURLString:email], NSHTTPCookieValue,
                             @"lxe", NSHTTPCookieName,
                             @"", NSHTTPCookieDomain,
                             @"/", NSHTTPCookiePath,
                             @"FALSE", NSHTTPCookieDiscard,
[cookies setCookie:testCookie];

Before this:

FBLoginDialog* dialog = [[[FBLoginDialog alloc] initWithSession:_session] autorelease];
dialog.delegate = delegate;
[dialog show];

Used to work...Any ideas of how can these work with this new sdk?
