I use the following code found on Facebook developer site to do a wall post:
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"http://developers.facebook.com/docs/reference/dialogs/", #"link",
#"http://fbrell.com/f8.jpg", #"picture",
#"Facebook Dialogs", #"name",
#"Reference Documentation", #"caption",
#"Dialogs provide a simple, consistent interface for apps to interact with users.", #"description", nil];
[_facebook dialog:#"feed" andParams:params andDelegate:self];
This shows a popup letting the user write his message and press publish or cancel.
Is there any way to know if the post has been successfully pusblished or not (cancellation or connection problem)?
Many thanks!
Try using specifying a delegate other than self to be able to capture the response of the dialog.
See: http://developers.facebook.com/docs/reference/iossdk/dialog/
You should call this dialog if the method you are calling requires
parameters to set up the dialog. You should set up your delegate to
handle the scenarios where the dialog succeeds, is cancelled by the
user, as well as any error scenarios.
As for the delegate: http://developers.facebook.com/docs/reference/iossdk/FBRequestDelegate/ I would assume it would be the request:didReceiveResponse: delegate.
EDIT
with additional feedback, your answer lies in the dialogDidComplete delegate listed on the link I gave in my original response.
I think you can do it by using - (void)dialogDidComplete:(FBDialog *)dialog; method of FBDialogDelegate.
+1 for Hlung and DMCS for their help but it looks like the feed dialog is getting more and more deprecated, and handling proper callbacks is fiddly (impossible?).
Plus the FB doc isn't up-to-date.
So I ended up using a (void)requestWithGraphPath instead of (void)dialog which requires an extra permission to post on user's wall but works better with the 2 following callbacks:
- (void)request:(FBRequest *)request didLoad:(id)result
- (void)request:(FBRequest *)request didFailWithError:(NSError *)error
Somewhat related to your question - I was trying to figure out which dialog had completed.
You can detect the parameters of the dialog, and check which one it is. I have this issue, as I send various dialogs, and want to know on the other end which one was a success or not.
- (void)dialogDidComplete:(FBDialog *)dialog {
// the song feed return
NSLog(#"params; %#",dialog.params);
if([[dialog.params objectFOrKey:#"ref"] isEqualtoString:#"songfeed"]){
// do stuff on return from this dialog
}
}

No email is outputted from the Facebook request. How do I get this? I need it for my login/signup process
- (void)request:(FBRequest *)request didLoad:(id)result{
NSLog(#"FACEBOOK RESULT %# ", result);
}
This is the initial request:
[facebook requestWithGraphPath:#"me" andDelegate:self];
The email property cannot be obtained without requesting additional permission to obtain it, see https://developers.facebook.com/docs/reference/login/email-permissions/.
My application uses the following code to first check whether the Facebook session is valid (self.facebook is a Facebook object initialized with initWithAppId):
if (![self.facebook isSessionValid]) {
NSArray* permissions = [NSArray arrayWithObjects: #"email", nil];
[self.facebook authorize:permissions];
} else {
// Since we have a valid session we can get the userinfo
[self getFacebookUserInfo];
}
Your application prompt will indicate "Using this app requires: * Your basic info * Your e-mail address" If the user authorizes you to obtain this information your access token returned will have bits in set to allow you to obtain the e-mail address, and the following will work:
-(void)getFacebookUserInfo {
[self.facebook requestWithGraphPath:#"me" andDelegate:self];
}
assuming your -(void)request:(FBRequest *)request didLoad:(id)result method is available (which it appears that it is).
Note that the full flow of SSO (Single Sign On) is not given here in this post, you'll need to go through https://developers.facebook.com/docs/tutorials/ios-sdk-tutorial/#implementsso in detail.
Note also that you may be using a deprecated API for iOS 6, you should look at https://developers.facebook.com/docs/tutorial/iossdk/upgrading-from-2.0-to-3.1/ before going further.
With 2.4 api, parameters are used in order to specify which user data items you are interested in receiving.
E.g.:
FBSDKGraphRequestConnection *connection2 = [[FBSDKGraphRequestConnection alloc] init];
FBSDKGraphRequest *selfRequest = [[FBSDKGraphRequest alloc] initWithGraphPath:#"me?"
parameters:#{#"fields":#"id,name,first_name,last_name,verified,email"}];
[connection2 addRequest:selfRequest
completionHandler:^(FBSDKGraphRequestConnection *innerConnection, NSDictionary *result, NSError *error) {
if (error) {
NSLog(#"%#", error);
return;
}
if (result) {
// get user data
NSMutableDictionary *facebookUserData = [NSMutableDictionary dictionaryWithDictionary:result];
NSLog(#"result=%#", result);
HOWEVER, they apparently messed up big time, as email is NOT CURRENTLY being returned for DEVELOPERS, and currently in development Apps.
Incidentally, it is IMPOSSIBLE to submit bugs on Apps in development, as they require approved apps in the feedback system...
I wonder how do they think we are going to make sure that something works BEFORE submitting an app for approval, or what is the logic of asking for an App Store id of an App which can't be approved BEFORE Facebook integration can be tested to the fullest.
Besides, who is the genius at Facebook who decides to break working code one day from another?
I am trying to post something from my IOS app to facebook feed. Below is the test I included in my code.
Facebook *facebook = [[Facebook alloc] initWithAppId:FB_APPID_REMOTE andDelegate:self];
// Create the parameters dictionary that will keep the data that will be posted.
NSMutableDictionary *fbParams = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"My test app", #"name",
#"http://www.google.com", #"link",
#"FBTestApp app for iPhone!", #"caption",
#"This is a description of my app", #"description",
#"Hello!\n\nThis is a test message\nfrom my test iPhone app!", #"message",
nil];
[facebook requestWithGraphPath:#"me/feed" andParams:fbParams andHttpMethod:#"POST" andDelegate:self];
However, I do not see the post updated to my facebook feed. Am i missing out anything here?
The method requestWithGraphPath returns an object of FBRequest. So you can check request.state to determine the status of the request, and check request.error to know what's exactly the problem.
Using AppDelegate will result in returning to the same page View you called from the ViewController. But as you are not getting any obvious error log or crashes, I think it is some issue with the Facebook graph protocol.
Replace "me/feed" with just "feed" as that works fine for me.
I've spent hours on this and can't get it to work. Basically I just want a button in my app that will 'Like' itself on Facebook.
I've created the app on dev Facebook and have an associated App Page.
In my code I request these permissions:
_permissions = [NSArray arrayWithObjects:#"publish_stream", #"publish_actions", #"user_birthday", nil];
I can retrieve a profile picture fine, but when I try to 'Like' using this code:
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
_facebook.accessToken, #"access_token",
nil];
[_facebook requestWithGraphPath:#"329756493773381/og.likes" andParams:params andHttpMethod:#"POST" andDelegate:self];
I get this error response:
(facebookErrDomain error 10000.)" UserInfo=0x20090590 {error={
code = 200;
message = "(#200) Requires extended permission: publish_actions";
type = OAuthException;
}}
When logging in on the app, Facebook asks me for permission to see my birthday, and tell's me it will Post on my behalf but it seems to not get the publish_actions permission.
Is there something i'm missing that I need to do?
I see Temple Run has a Facebook Like button and offers bonus coins for pressing it. This is what I wish to achieve.
EDIT -------
I've changed my permissions to just #"publish_actions", #"user_birthday" and now the auth dialogue says
"This app may post on your behalf, including objects you liked and
more"
which seems to be the publish_actions permission, however I was still getting the error
message = "(#200) Requires extended permission: publish_actions";
I've changed this line:
[_facebook requestWithGraphPath:#"329756493773381/og.likes" andParams:params andHttpMethod:#"POST" andDelegate:selrf];
to this:
[_facebook requestWithGraphPath:#"329756493773381/og.likes" andDelegate:self];
and I do now get a response back, although it doesn't post a 'like'
This is the result response:
{
data = (
);
paging = {
next = "https://graph.facebook.com/329756493773381/og.likes?sdk=ios&sdk_version=2&access_token=BAAGeAp3ZBGwoBAPICjlgB5zK0YECyP8yElf8hJoMrx8Qs4vjeZAK5PlXFAVbGM1JyXHE0wZBvU0aBeCzCUTZBejQgoJ44CAIQsrG64TfrHdxjMqWD&format=json&offset=25&limit=25";
};
}
Any idea what to try next?
EDIT 2 ---------------
I'm making progress with this.
I've added the users id to the graph request like this
NSString *graphPath = [NSString stringWithFormat:#"%#/og.likes",facebookID];
and used these parameters
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"AAAGeAp3ZBGwoBABvKjsPZAoQQNG9cDPJI2v2TI8acyyPSNtm9ZBkfydHqVZAjSKWSbLuvFwxyxSrCts7kFZCnh7Y6f5PFNlWb6smF8XF33wlRZBgfLyhT1", #"access_token",
#"http://samples.ogp.me/329756493773381", #"object",
nil];
and now I get a like showing up on my timeline :-)
I was using the access-token supplied by the Facebook login, but it seems the one supplied by the graph object is different.
Now, the like that i'm seeing has this pattern:
Darren likes object on MyAPP
Is it even possible to have it as
Darren likes MyAPP
with it linking to the app Facebook page?
Thanks
Check if you have done the steps below:
https://developers.facebook.com/docs/opengraph/tutorial/
"Note: The user-prompt for this permission will be displayed in the first screen of the Enhanced Auth Dialog and cannot be revoked as part of the authentication flow." - link
Try this if you havent already:
Auth Dialog -> Configure how Facebook refers users to your app - > Add publish_actions permissions.
https://developers.facebook.com/docs/opengraph/authentication/
"To enable the new Auth Dialog, go to the App Dashboard, and enable the Enhanced Auth Dialog setting in the Advanced section of your app." -link
Hope this helps!
This seems to be the same problem I was having on this SO question:
Facebook iOS SDK 3.0, implement like action on a url?
But if you want to like you facebook page in the app, there is no way to do that in Objective C. Only with the javascript Like button which you can generate here:
https://developers.facebook.com/docs/reference/plugins/like/
The way Temple Run does it is to display the Like button in a web-view, so their like button is actually on their server, this is perhaps an ugly-hack but will work for liking a page.
As soon as the user is logged in, I retrieve the user info using this code:
[_facebook requestWithGraphPath:#"me" andDelegate:self];
It worked for the first few times, but it eventually returned an error. I thought it was a session thing since I have "offline_access" on my permissions. I logged out from Facebook and compiled again from a clean build and it still returns this error:
Error Domain=facebookErrDomain Code=10000 UserInfo=0x54a2930 "Operation could not be completed. (facebookErrDomain error 10000.)"
I'm assuming my access token is valid since I can do posting. Am I right to assume that?
I also noticed that whenever I log in, Facebook doesn't redirect me to ask permission if I allow my app to access my user info.
Can anyone tell me what's wrong?
Answer on authorize command seems to be different. Now, there's no expiration date as it was before. I tried with forcing isSessionValid to return TRUE, and it works.
isSessionValid checks accessToken AND expirationDate. As there's no expiration date, the function return FALSE.
Don't know if it's a temporary modification from facebook, or definitive one. In this case, SDK must be fixed, I presume. And a new call must retrieve expirationDate.
Here's a temporary fix I've used. You can find this method line 46 in FBLoginDialog.m
- (void) dialogDidSucceed:(NSURL*)url {
NSString *q = [url absoluteString];
NSString *token = [self getStringFromUrl:q needle:#"access_token="];
NSDate *expirationDate = [NSDate distantFuture];
if ((token == (NSString *) [NSNull null]) || (token.length ==0)) {
[self dialogDidCancel:url];
[self dismissWithSuccess:NO animated:YES];
} else {
if ([_loginDelegate respondsToSelector:#selector(fbDialogLogin:expirationDate:)]) {
[_loginDelegate fbDialogLogin:token expirationDate:expirationDate];
}
[self dismissWithSuccess:YES animated:YES];
}
}
Does everyone with this issue request the offline_access permission? It's the only reason I can see an expiration date not being sent. Maybe try not requestion the offline_access permission.
I've had same problem. I checked my privacy settings,permissions,other method etc..., but I couldn't solve it.
Many sites said "check permission for accessing to offline_access/read_stream/publish_stream",I think these are important too,but I couldn't fix it.
Then I found following solution finally, it works fine.
You should change "safariAuth:YES" to "safariAuth:NO" on "Facebook.m" file.
- (void)authorize:(NSArray *)permissions
delegate:(id<FBSessionDelegate>)delegate {
[_permissions release];
_permissions = [permissions retain];
_sessionDelegate = delegate;
//[self authorizeWithFBAppAuth:YES safariAuth:YES];
//You can get auth_token in iOS App!
[self authorizeWithFBAppAuth:YES safariAuth:NO];
}
Then you can use following method to get your own info if you are logged in.
[facebook requestWithGraphPath:#"me" andDelegate:self];
if you are not logged in, You should login by following method first.
permissions = [[NSArray arrayWithObjects:
#"email", #"read_stream", #"user_birthday",
#"user_about_me", #"publish_stream", #"offline_access", nil] retain];
if (![facebook isSessionValid]) {
[facebook authorize:permissions delegate:self];
}
Following post saved me.Thank you so much!
How to retrieve Facebook response using Facebook iOS SDK
Good Luck & Happy-coding!
Thank you.
I've had this problem, mainly because my Facebook account has is maxed on privacy.
It's most likely the permissions that you passed in during login. BY default it will only give access to public info. Remember there is less and less info that is public in Facebook.
Try changing your permission to something like "read_stream",nil
Then instead of [_facebook requestWithGraphPath:#"me" andDelegate:self];
Try using [_facebook requestWithGraphPath:#"me/home" andDelegate:self];
This should return your news feed.
Worked for me 5 mins ago.
Not much to add here, doesn't work here too. I use the iOS SDK to post to the stream and it worked until yesterday. Today my client called me and complained. Ugh.
I have requested the offline access permission and of course the "publish_stream" permission...
How to add news via FBConnect?
I have the following code:
NSString *newsBody = #"[{\"message\": \"News message\" }]";
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObject:newsBody forKey:#"news"];
[[FBRequest requestWithDelegate:self] call:#"facebook.dashboard.addnews" params:params dataParam:nil];
After I sent the request I received the success responce. But I can't see the new news in the facebook account.
Also, I tried to add full info into news parameter (http://wiki.developers.facebook.com/index.php/Dashboard.addNews):
NSString *newsBody = #"[{\"message\": \"News message\",\"action_link\": {\"text\": \"link text\",
\"href\": \"http: //google.com\"} }]";
But this request returns error.
Any ideas?
I found the answer. The FBStreamDialog should be used to publish the news. It means that the custom interface cannot be used for this purposes. :(
Also, just wanted to say that FBConnect it's a one big mess!! Currently fighting with the bug when after clicking Cancel button in the FB dialog the dialog firing the event dialogDidSucceed but not dialogDidCancel. Such a big mess!!!
