I'm stuck in a situation where I am not able to use the structured 'askfor' or 'send' requests through IOS SDK. I always get an error which says that facebook could not find any object with that particular object id. I created the object by using the Object Types section under the Open Graph section in the App settings page. I have tried the same thing with test user account too, but no avail.
Used this as the guide - https://developers.facebook.com/docs/games/requests/v2.2#gifting
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
toList, #"to", // Comma separated string of FB ids.
dataStr, #"data", // Data to be sent with request
objectId, #"object_id", // Object as retrieved from Object Types
#"askfor", #"action_type", // Preset action type [send/askfor/turn]
];
[FBWebDialogs presentRequestsDialogModallyWithSession:nil
message:messageStr
title:titleStr
parameters:params
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
if (error) {
I get an error within the returnUrl (error 100) which says facebook cannot find an object with the given ID.
Have been stuck at this for quite sometime now, any help greatly appreciated! Thanks in advance!

I am using this line of code for getting count of likes on facebook post
NSString *postId = #"1234567890_1234567890";
NSMutableDictionary* photosParams = [NSMutableDictionary dictionaryWithObjectsAndKeys:postId,#"ObjectId",nil];
NSString * str = (NSString *) [[[FBSDKGraphRequest alloc] initWithGraphPath:#"/{object-id}/likes"
parameters:photosParams
HTTPMethod:#"GET"]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if ([error.userInfo[FBSDKGraphRequestErrorGraphErrorCode] isEqual:#200]) {
NSLog(#"%#",[error localizedDescription]);
}
}];
but I am getting error of unsupported url, any one have Idea what parameter I use to get result. I am using updated version of facebook api
As
https://developers.facebook.com/docs/graph-api/reference/v2.3/object/likes
states, you need
The same permissions required to view the parent object are required to view likes on that object.
That means that the permission setting for Posts (https://developers.facebook.com/docs/graph-api/reference/v2.3/post) apply:
For page posts, public posts by the page are retrievable with any valid access token. Posts by people on the page, posts by people which mention the page, or targeted page posts (by language or geography, for example) may require a user or page token.
A user access token with read_stream or user_posts permission for any other posts
Are you sure you're adding an Access Token to your request?
You can request multiple posts at once like this:
/?ids={object_id1},{object_id2}&fields=id,created_time,likes.summary(true).limit(0)
I want to get the app user ID for Facebook, as described here:
https://developers.facebook.com/docs/ads-for-apps/custom-audiences-for-mobile-apps/
The code snippet they give is:
[FBRequestConnection startForCustomAudienceThirdPartyID:nil
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
NSString *id = error ? nil : [result objectForKey:#"custom_audience_third_party_id"];
// Stash off this id, send it to your server, etc. Use later to construct
// a custom audience. A result of 'nil' means that either the user can't be
// identified, or they've limited ad tracking via iOS 6.
}
];
This always returns error 400 for me. Answers like this suggest that it needs to be used as part of a larger piece of code but there's no mention of this on the Facebook page.
Can I just use the snippet above, or do I need to implement something around it?
I got this from the FB developer page:
Discussion:
This method will thrown an exception if either <[FBSettings defaultAppID]> or <[FBSettings clientToken]> are nil. The appID won't be nil when the pList includes the appID, or if it's explicitly set. The clientToken needs to be set via <[FBSettings setClientToken:]>.
.....
Please check the conditions above first. Ass per documentation
startForCustomAudienceThirdPartyID: -> should actually point to the current FBSession
Right after the session is created do this: [FBSession setActiveSession:session];
Answered here: Facebook iOS SDK 3.1: "Error: HTTP status code: 400"
I'm using the iOS SDK with the native dialog to try to post an object and action.
When I call presentShareDialogWithOpenGraphAction, the Facebook app opens, briefly shows the dialog with my post in it, and then returns to my app with the error:
Could not generate preview text
My code looks like this:
NSDictionary* object = #{
#"fbsdk:create_object": #YES,
#"type": #"appsterbator.app_idea",
#"title": #"test",
#"url": #"http://test.com",
};
id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
[action setObject:object
forKey:#"app_idea"];
[FBDialogs presentShareDialogWithOpenGraphAction:action actionType:#"app_idea.create"
previewPropertyName:#"app_idea"
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
NSLog(#"%#", error);
}];
Also, is it possible post an Open Graph object that doesn't actually have a URL?
I had the same symptoms, but a different fix. Facebook SDK 3.5.* since the Share Dialog came out of beta.
I had a custom Object Graph story: Solve -> Puzzle. This was my first time working with OG, so this might seem obvious to someone more familiar with it, but it stalled me for long enough that I wanted to share.
I ran through the Share Dialog examples on the developer site, but the Open Graph related sharing would not work via simple copy paste. I figured because the OG objects were tied to the App ID and URL host etc. I setup my web host so that I could serve OG data for my objects, and configured my app to allow that host etc..
So I set about adapting the sample code to use the parameters present in the "opengraph / stories -> Get Code" popover. Setting the platform to iOS SDK, I got the following for Create Action:
NSMutableDictionary<FBGraphObject> *action = [FBGraphObject graphObject];
action[#"puzzle"] = #"http://samples.ogp.me/463417983744195";
[FBRequestConnection startForPostWithGraphPath:#"me/shapeshuffle:solve"
graphObject:action
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
// handle the result
}];
I swapped my story and app specific values into the sample code, leading to the the error and symptoms described in the question.
I spent longer than I care to admit fiddling with the server hosting my OG object, FB App settings, different ways of popping the share dialog etc.
The root of the problem was that on popping the dialog, FB was unable to match the action and object with the configuration in my app - hence the slightly vague error code relating to generating the preview text. FB wasn't finding the action because "me/shapeshuffle:solve" (the action string in the "Get Code" tool) doesn't resolve. If I understood all the different options available to me in the Get Code tool, I might have avoided this, but remember, all I wanted was to pop a share dialog. Seemed simple.
I worked with the Graph API explorer via this useful tutorial, and wound up with the following mapping from the strings I got from the FB tool to what actually worked:
Action:
me/shapeshuffle:solve => shapeshuffle:solve
Lots of pain for 3 little characters. Here is what my finished code looks like:
NSString *objectUrl = [NSString stringWithFormat:#"%#puzzleId=%d", #"http://myhost.com/puzzle/object?", puzzleId];
id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
[action setObject:objectUrl forKey:#"puzzle"];
[action setObject:timeString forKey:#"time"];
[FBDialogs presentShareDialogWithOpenGraphAction:action
actionType:#"shapeshuffle:solve"
previewPropertyName:#"puzzle"
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
if(error) {
NSLog(#"Error: %#", error.description);
} else {
NSLog(#"Success!");
}
}];
Had the same issue. Make sure the App Domains in Basic Info contains the oAuth domain. The odd thing I found is that in order to add this you need to enable this can only be added if you enable Page Tab or Mobile Web or one of the other options.
I think i may know the reason that (#"url": #"http://test.com")->this may use the facebook app developer center offer.
click Open Graph
click Stories
then you will see your custom story on right side
click Get Code,then you will get the URL you need!
and (#"type": #"appsterbator.app_idea")->this may need use like this->(your_app_namespace:action_type)
Good luck!
To problem with: "Could not generate preview text" come from attempts to share the same content several times.
Try to change content that you share each time you check the functionality of open graph.
A condition that causes this which has not been described yet is case sensitivity of the action and property name, which must be lowercase. To illustrate note the 'must_be_lowercase' in the following:
id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
[action setObject:#"http://link/" forKey:#"**must_be_lowercase**"];
[FBDialogs presentShareDialogWithOpenGraphAction:action
actionType:#"xxxx"
previewPropertyName:#"**must_be_lowercase**"
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
if(error) {
NSLog(#"Error: %#", error.description);
} else {
NSLog(#"Success!");
}
}];
This is a lovely generic error message! Another possible cause I've encountered is the size of the OpenGraph image being posted.
Although Facebook documentation states images must be 200x200px to 1500x1500px, my initial attempts with a 350x350px image failed with the “Could not generate preview text” error. The same image at 600x600px on the other hand works perfectly.

I'm trying to post achievements to users' Facebook graphs with the SDK 3.1.1, but I keep getting a "HTTP status code: 400" error in the log every time the achievement URL is sent. I've registered the URL correctly and everything checks out with Facebook's little debugger tool when I paste the URL in. Publishing permissions are also granted and the whole authentication process happens without a hitch. I'm using a dummy user ID at the moment, but here's the code I'm working with inside the function that sends the achievement...
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
[NSString stringWithFormat:#"%#",
[achievementURLs objectAtIndex:achievement]], #"achievement",
nil];
userID = 100004505160614;
[FBRequestConnection startWithGraphPath:[NSString stringWithFormat:#"%i/achievements", userID] parameters:params HTTPMethod:#"POST" completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
}];
Any ideas where this error might be coming from?
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?
