I'm trying to post an Open Graph Story, being logged to my app with Facebook test account. Story contnents: Name shared a link.
Facebook's instructions to get a permission is a vicious circle!
To post I need a permission, For permission I got to post something.
So when I'm trying to post a story from the app. App goes to Facebook app, creates a template for post. But when press "Publish" nothing's happen.
Please, help me to solve a problem.
Our company tried everything, changed code etc, but I think it's Facebooks problem. Please, help me to find out why posts do not publish to Facebook.
PS: We do not use share dialog in this case, we are using Open Graph with API 2
If you just want to share a link then use the following code:
FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
content.contentURL = [NSURL URLWithString:#"http://developers.facebook.com"];
[FBSDKShareDialog shareFromViewController:self
withContent:content
delegate:nil];
In the composer leave 'Say something about this...' blank and the story will show up in the Timeline as "Name shared a link"
If it is a custom OG story, then use the Share Dialog; you do not need to explicitly get publish_actions permission.
If Share Dialog does not seem to post to Timeline, set the delegate for the dialog and you can use the delegate method to investigate the cause.
-(void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error {
NSLog(#"Error: %#", error);
}
As for creating actions and objects, you can do so in your app dashboard:
https://developers.facebook.com/apps/<your-facebook-app-id>/open-graph/
If you need permissions to make Graph API calls then implement login with Facebook and it is here that you request the permissions that your app needs. For example:
FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init];
loginButton.readPermissions = #[#"public_profile", #"user_photos"];
loginButton.publishPermissions = #[#"publish_actions"];
Once you have the permissions in place you can make Graph API calls.

I am creating an iOS app where I want to allow the user to like a specific URL. I've tried to use the following code (as mentioned on the Facebook developers page) to like a specific url:
**- (IBAction)likeClicked:(UIButton *)sender {
SLAppDelegate *appDelegate = [[UIApplication sharedApplication]delegate];
[FBSession setActiveSession:appDelegate.session];
if (appDelegate.session.isOpen)
{
NSMutableDictionary<FBGraphObject> *action = [FBGraphObject graphObject];
action[#"object"] = #"http://samples.ogp.me/226075010839791";
[FBRequestConnection startForPostWithGraphPath:#"me/og.likes"
graphObject:action
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
NSLog(#"Error %#",error.localizedDescription);
NSLog(#"result %#",result);
// handle the result
}];
}
}**
But the above code only allows me to like the URL if I am authorized as an admin of that app on the facebook developer page.
If I am not an admin to the app with that specific app id , I get an error description as following:
Error The operation couldn’t be completed. (com.facebook.sdk error` 5.)
There are different solutions given on Stack Overflow for this but none of them seem to be working for me. I've checked for permissions and I have added the "publish_actions" permission to permissions list.
Is there another reason why i might be getting this error?
Is there another workaround using which i can like a specific URL on facebook?
There would be couple of places to check
- Is your Facebook app under "sandbox mode", if it is you will have to turn it off once you are sure with your development.
If you have just created a FB graph action:
You are required to submit the action through the FB developer console and it usually takes couple days for them to approve, and once approved other users can start using the "like" action.
Until you get the action approved, only the App developers, testers and admins (on the FB developer site) for this particular app would be able to complete the action and see the results on their FB timeline.
I have been searching for tutorials on google for posting some text on google plus. But it seems like there are none.
I have also tried to go through the docs provided by google for developers of mac and iPhone but can't find anything that will solve my problem. Also there are little information on how to get the user login to there google plus account.
I am not sure what to do for the user login, do I have to use some GTLObject or use UIWebView like foursquare for user login.
Here is a list of docs that I had went through.
http://code.google.com/p/google-api-objectivec-client/wiki/Introduction
http://code.google.com/p/google-api-objectivec-client/wiki/BuildingTheLibrary
http://code.google.com/p/gtm-oauth2/
As it turns out there are only a limited number of api's available for google + developers and that also only as GET calls according to the developer of google + page my question will not get any definite answers as google is in the process of creating new api's for accessing user information on google plus.
https://developers.google.com/+/api/
Also you can use the google client sdk provided by google but it is much easier to show a webview for user login. I managed to get the people list from google plus.
The steps are same as for getting the access token as in foursquare. Just with some small changes.
in viewdidload method.
NSString *authStr = #"https://accounts.google.com/o/oauth2/auth?client_id=client_id&redirect_uri=http://somevalidurl.com&scope=https://www.googleapis.com/auth/plus.me&response_type=token";
as a url for loading request in webview. People should note one thing here that you need to create a client id in api console for your app that is web based and not as installed for this purpose as you wont we getting any option to enter any website url for callback which is very important in this case.
and in webview delegate method webViewDidFinishLoad:
NSString *urlStr = [[webView.request URL] absoluteString];
NSArray *array = [urlStr componentsSeparatedByString:#"access_token="];
if(array.count > 1)
{
NSString *oauth_token = [[[array objectAtIndex:1] componentsSeparatedByString:#"&"] objectAtIndex:0];
//do something with the oauth token after this.
}
I wrote a code snippet to signin and post simple text to Google Plus with URL and thumb Image URL.
Try it

I'm trying to post a link + status through my app, using this "popup" facebook window where the user is asked to log in, then asked to allow my app to his profile. Then I want him to be able to write a status, with a link I specify attached. This facebook popup would be triggered by a button, not at start of my app (in the documentation I found that they want me to implement it in the appDidFinish launching method...) But I don't want that, I want it like the popup facebook window is only triggered per button tap.
I'm trying to figure this out for a few days now, but finding that all tutorials are out-dated and the Facebook Developer documentation is very weak- atleast for for me. I already downloaded the Facebook-iOS-SDK with the API and JSON included from GitHub. I already did a few attempts, but the furthest I got is that the user was asked to log in, but not through my app, instead Safari opened and the log in field were there, not in my app.
Could someone please post some code, a basic tutorial I might find helpful, or point me to a good online tutorial? I already tried to post to iPhone Dev SDK forums, where other people also asked for this, but never got any help. So could someone out here please put together something that would help out all the newbies?
I want my login screen look like this, and the rest should be in a popup too:
http://www.facebook.com/photo.php?pid=439332&l=c04b210914&id=100001688115647
Thanks a lot in advance!
There is already a sample code in facebook-ios sdk you can see that there are already the code available for some things. Here is a code snippet from the older facebook API but this should work with the newer graph api too
- (void)setStatus:(id)target {
NSString *statusString = #"Testing iPhone Connect SDK";
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
statusString, #"status",
#"true", #"status_includes_verb",
nil];
[[FBRequest requestWithDelegate:self] call:#"facebook.users.setStatus" params:params];
}
WHat you can do is create a controller to handle all the facebook requests like a singleton class and on tap of button do something like this
- (IBAction)showFBLoginDialog:(id)sender {
if(LoggedInFacebook == NO) {
FBLoginDialog *dlg = [[[FBLoginDialog alloc] initWithSession:faceBookController._session] autorelease];
[dlg show];
}
else {
[faceBookController logoutUser];
}
}
If you need further help search on google and stackoverflow you will find a bunch of.
I have seen a lot of questions here regarding the Facebook Graph API but I still haven't find a solution for simple 'login'/'logout' operations using it. Looks like the Single Sign-On style is causing more confusion than benefits.
I'd like to know if it is possible have the following situation:
Enter in the app (no accessToken/expirationDate created).
Perform a login using SSO by calling authorize:delegate: method (application goes background and the login is made in the 'global' scope (Facebook App/Mobile Safari), asking for the user credentials.
Enter back in the app (now logged in, both accessToken and expirationDate are saved to NSUserDefaults).
Perform a logout by calling the logout: method (now logged out, both accessToken and expirationDate are removed from NSUserDefaults)
Attempt to perform a login again, with exactly the same steps done in 2.
I realize that when I call logout:, I do really log out from Facebook (accessToken is invalidated) from my App scope, not from the global scope (Facebook App/Mobile Safari). In 5.) when I try to log in again, the application goes to background and the login attempt is made again in Facebook App/Mobile Safari as usual, however I'm getting a screen saying that I'm already logged in:
You have already authorized .... Press "Okay" to continue.
Logged in as ... (Not You?).
It's a strange behavior for the user that has just logged out in my App.
My question is:
"Can I really log out from facebook (I mean 'global' scope) from inside my App? This would affect other apps using the facebook credentials too. However, if I can't to do this, how can I avoid the 'strange behavior' describe above?
Thanks
Eduardo,
I feel your pain! I spent the better part of a day working on this issue. I have discovered that when you use SSO and the call:
Called from your code:
[facebook logout:self];
Facebook API method:
- (void)logout:(id<FBSessionDelegate>)delegate {
self.sessionDelegate = delegate;
[_accessToken release];
_accessToken = nil;
[_expirationDate release];
_expirationDate = nil;
NSHTTPCookieStorage* cookies = [NSHTTPCookieStorage sharedHTTPCookieStorage];
NSArray* facebookCookies = [cookies cookiesForURL:[NSURL URLWithString:#"http://login.facebook.com"]];
for (NSHTTPCookie* cookie in facebookCookies) {
[cookies deleteCookie:cookie];
}
if ([self.sessionDelegate respondsToSelector:#selector(fbDidLogout)]) {
[_sessionDelegate fbDidLogout];
}
}
The facebook API does invalidate the access token and expirationdate variables and attempts to delete the mobile Safari cookies, but for some reason, probably Apple's fault the cookies are not really deleted. So when you attempt to login in the next time your mobile Safari will see the cookie and it says:
"You have already authorized .... Press "Okay" to continue. Logged in as ... (Not You?)."
Until either Facebook finds a fix or Apple fixes their broken API we must bypass SSO through Safari. Below are the changes I made to Facebook.m in order to force the old login dialog. If you used these changes they may not work forever but it is my guess that they will work for a very long time. Also to be sure this worked with the most recent facebook API I updated to the latest as of this post (Nov 2011 build).
Called from your code:
[facebook authorize:permissions];
Facebook API method:
- (void)authorize:(NSArray *)permissions {
self.permissions = permissions;
// [self authorizeWithFBAppAuth:YES safariAuth:YES];
[self authorizeWithFBAppAuth:NO safariAuth:NO];
}
If this helps you please up rate this thread and my post to help others find it.

I'm afraid the answer is no, you can't do this.
Your application is in a sandbox, and can't write outside, where global cookies are (for mobile safari) and Facebook app settings (in Facebook app preferences/cookies I think)
You can only warn your user to logout outside of your app...
...Or you can just not use facebook api SSO, but in app login webform, like I do for other reasons.
If you choose that option this pull request might save you some time ;)
Hii ,
its not possible , the reason is for Single Sign On (SSO) is not to make user login everytime, he logouts , instead if the user logs in anyone of FB enabled apps - it will use that to login again - This is because the device is mostly used by single person in this case only one user can login in Facebook.
you can't control any app outside of your app - for Example - if u login with Gmail & when you open google.com you can see your username there is currently logged In which has SSO,
In new SDK of Facebook, you can set login button loginBehaviour property
Below code in swift ...
let fbButton = FBSDKLoginButton()
fbButton.loginBehavior = .Web
Answer already done, but I just want to clarify it. May be it saved somebody's time.
Go to Facebook.m and change line
[self authorizeWithFBAppAuth:YES safariAuth:YES];
to
[self authorizeWithFBAppAuth:YES safariAuth:NO];
It will cause login window appear inside the app. Logout will work perfect. In other words, it will work as it used to in older versions of OS.
in addition to kishnan94 answer. the objective c version is ;
if you want a modal to open up and ask for facebook credentials seperately from Safari or Facebook app, just use the latest facebook sdk and set the login behaviour
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login setLoginBehavior:FBSDKLoginBehaviorWeb];
this will make the logout process more convenient and less confusing for users without using safari or facebook app accounts.
It seems that this is a bug of Facebook SDK. In a case of the Facebook app is installed on device, access_token is renewed. In other hand, access_token and expirationDate could not be changed. :((
I want to publish information to user's wall from iphone application. I am using the Facebook SDK for iphone. I found in the documentation that I should use FBStreamDialog but this loads a form to the user and s/he write the story to be published, I don't want this behavior. I want to publish user actions at my application and user just needs to click share button, then the application should fill a template story and publish.
I found this use case was available before with FBFeedDialog but this is not supported via the API now.
Any suggestions, what I should do?
//Modified
here's an example for David's solution:
NSString *att = #"{\"name\":\"i\'m bursting with joy\",\"caption\": \"User rated the lolcat 5 stars\", \"description\": \"a funny looking cat\"}";
NSDictionary *attachment = [NSDictionary dictionaryWithObject:att forKey:#"attachment"];
[[FBRequest requestWithDelegate:self] call:#"facebook.stream.publish" params:attachment];
#"stream.publish"
I use this code occur error "The user hasn't authorized the application to perform this action"
