I have used FacebookSDK.framework for Facebook integration in my application. I have to like one facebook page from application. I have used following code for liking page.
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:#"https://www.facebook.com/demoappname"
, #"object",
nil
];
/* make the API call */
[FBRequestConnection startWithGraphPath:#"me/og.likes"
parameters:params
HTTPMethod:#"POST"
completionHandler:^(
FBRequestConnection *connection,
id result,
NSError *error
)
{
NSDictionary *currentResult= [(NSArray *)[result data] objectAtIndex:0];
if(!error)
{
NSLog(#"there is no error");
}
else
{
NSLog(#"There is something wrong at here.");
}
}];
But I am not clear what I have to pass in "object" parameter. Can anybody help to what I am doing wrong at here.
Thanks,
If you read this documentation, it says-
The og.likes action can refer to any open graph object or URL, except for Facebook Pages or Photos.
So, liking a page with Graph API isn't possible.
The only thing you can do- add a Like Button to the page in your app.

I'm developing a social networking app. I've integrated Facebook SDK 3.14 in my iOS App. Now, I want to get the list of all my Facebook friends so I can invite those friends who are not using the app and send friend requests to those friends who have already installed the app.
I can get the list of friends who already use my apps using "/me/friends".
[FBRequestConnection startWithGraphPath:#"/me/friends"
parameters:nil
HTTPMethod:#"GET"
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
NSLog(#"All == %#", result);
}];
It gives friends' Facebook ids (ex. id = 654330727444458) in response so that I can send friend requests to them.
To get the list of all Facebook friends who have not downloaded the app and if I want to invite those, I need to get all friends using "me/taggable_friends" (Please correct me if I'm wrong).
[FBRequestConnection startWithGraphPath:#"/me/taggable_friends"
parameters:nil
HTTPMethod:#"GET"
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
NSlog("%#", result);
}];
In the taggable_friends response I'm getting friend's id as id = "AaLYBzZzHdzCmlytqyMAjO0OLDZIOs74Urn93ikeRmmTB3vX_Xl81OYUt4XnoWG0BDLuX67umVkheVdDjzyvm0fcqMqu84GgM9JnNHc-1B63eg" which is friend's token id and it's not unique. I couldn't use it instead, have to use Facebook Id of friend to invite them. Unfortunately, I couldn't get it in the taggable friend response.
This is only possible on the Facebook API v1 which stops working next April or so. Even now only existing Facebook apps will allow you to use V1 so if you don't have an old enough app you are not able to do this. In V2 you can only get friends who have also signed in to the same app but the user id's are unique to the application to prevent exactly this. I guess Facebook reasons that by doing this is stops people spamming their friends via apps so much :/
As #joelrb says you can create a canvas app for a game and use invitable_friends but FB will vet your "game" so you can't really cheat.
See https://developers.facebook.com/docs/apps/changelog/ for more info.
TLDR; post to wall is all you can do. Tough. Sorry.
Use the installed field of a user. Like so:
NSMutableArray *notYetUsers = [NSMutableArray array];
FBRequest *fbRequest = [FBRequest requestForGraphPath:#"me/friends?fields=installed"];
[fbRequest startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
NSAssert(!error, error.localizedDescription);
NSArray *friends = [(NSDictionary *)result objectForKey:#"data"];
for (NSDictionary<FBGraphUser> *user in friends) {
if ([user[#"installed"] isEqual:#(NO)])
[notYetUsers addObject:user];
}
}];
notYetUsers would contain all friends who have not installed the app yet.
- (void)getFBFriendsWithCompletion:(void (^)(NSError *, id))callback
{
NSString *query = #"select uid, name, is_app_user "
#"from user "
#"where uid in (select uid2 from friend where uid1=me() )";
NSDictionary *queryParam =
[NSDictionary dictionaryWithObjectsAndKeys:query, #"q", nil];
// Make the API request that uses FQL
[FBRequestConnection startWithGraphPath:#"/fql"
parameters:queryParam
HTTPMethod:#"GET"
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
if (callback)
callback(error, result);
}];
}
- (void)foo
{
[self getFBFriendsWithCompletion:^(NSError *error, id result) {
if (!error)
{
NSMutableArray *friendsUsingApp = [NSMutableArray array];
NSMutableArray *friendsNotUsingApp = [NSMutableArray array];
for (NSDictionary *data in result[#"data"]) {
if ([data[#"is_app_user"] boolValue] == NO) {
[friendsNotUsingApp addObject:data];
} else {
[friendsUsingApp addObject:data];
}
}
// Do something with friendsUsingApp and friendsNotUsingApp
}
}];
}
taggable_friends refers to a list of friends that can be tagged or mentioned in stories published to Facebook. The result you got is just a tagging token which can only be used in order to tag a friend, and for no other purpose.
Although this refers to a game app, it's easier I think if you use the invitable_friends API. But it requires a Facebook Canvas app implementation. You may just provide a notice in your Canvas for users to just use the mobile app instead, etc.
This is the tutorial that uses invitable_friends API: https://developers.facebook.com/docs/games/mobile/ios-tutorial/
And, the invitable_friends API details:
https://developers.facebook.com/docs/games/invitable-friends/v2.0
You can try this to get the IDs of Friends app users:
NSMutableArray *appFriendUsers = [[NSMutableArray alloc] init];
[[FBRequest requestForGraphPath:#"me/friends?fields=installed"]
startWithCompletionHandler:
^(FBRequestConnection *connection,
NSDictionary *result,
NSError *error) {
//if result, no errors
if (!error && result)
{
//result dictionary in key "data"
NSArray *allFriendsList = [result objectForKey:#"data"];
if ([allFriendsList count] > 0)
{
// Loop
for (NSDictionary *aFriendData in allFriendsList) {
// Friend installed app?
if ([aFriendData objectForKey:#"installed"]) {
[appFriendUsers addObject: [aFriendData objectForKey:#"id"]];
break;
}
}
}
}
}];
I am working on Facebook like and comment in ios,i am getting the response i.e id of a like object.But it is not showing in Facebook.I am using this code to like a object.
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
#"http://samples.ogp.me/226075010839791", #"object",
nil
];
/* make the API call */
[FBRequestConnection startWithGraphPath:#"/me/og.likes"
parameters:params
HTTPMethod:#"POST"
completionHandler:^(
FBRequestConnection *connection,
id result,
NSError *error
) {
/* handle the result */
}];
I am getting one more problem i.e if i clicked on another object of a same user it is giving an error.
message = "(#3501) User is already associated to the object type, website, on a unique action type Like. Original Action ID: 654561277932515";
Please help me.
I am trying to post dictionary to facebook in which image is attached, when user click on the image then should redirect the user to a link. I need to share the dictionary in the format shown in the attached image. If anybody knows that how can I achieve
the attached format then please let me know.
Please try this code , i also use this code for my app and resolve a issue ..
- (void)sendDataOnfacebook {
[self performPublishAction:^{
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:#"FASHMOD", #"name",
strFBPostUrl,#"link",
strFBPostTitle, #"message",
strFBPostImageUrl,#"picture",
#"Be a fashion model",#"description",nil];
[FBRequestConnection startWithGraphPath:#"me/feed"
parameters:params
HTTPMethod:#"POST"
completionHandler:^(FBRequestConnection *connection,id result,NSError *error)
{
NSLog(#"Shared successfully");
NSLog(#"status %# %# ",result,error);
}];
}];
}
I am using facebook sdk and need to share details to facebook timeline. I am using the following api call.
[FBRequestConnection startWithGraphPath:#"/feed"
parameters:dictionary
HTTPMethod:#"POST"
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error)
{
if (!error) {
[VBUtility showAlertWithTitle:#"Facebook" message:#"Deal details posted successfully"];
}
}];
The story is published on facebook, not at user's timeline but user's newsfeed (The document tells this method does - posts and links published by this person or others on their profile.). I have also tried with /home method call. While I tried with the built in facebook share,
SLComposeViewController *fbPost = [SLComposeViewController
composeViewControllerForServiceType:SLServiceTypeFacebook];
it is perfectly published to user's timeline as well as in news feed. I have configured the app in the developer.facebook.com. Do I need to mention any permissions here. Does any one can help me finding the mistake?
Permission Request,
NSArray *permissions = [[NSArray alloc]initWithObjects:#"publish_actions",#"user_birthday",#"publish_stream",#"user_about_me",#"email",#"basic_info",nil];
The parameters passed are,
NSMutableDictionary *dictionary = [NSMutableDictionary dictionaryWithObjectsAndKeys:
app_id, #"app_id",
name,#"name",
caption, #"caption",
description,#"description",
link, #"link",
picture, #"picture",
#"1",#"fb:explicitly_shared",
nil];
Try this,
[FBRequestConnection startWithGraphPath:#"me/feed"
parameters:dictionary
HTTPMethod:#"POST"
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error)
{
if (!error) {
[VBUtility showAlertWithTitle:#"Facebook" message:#"Deal details posted successfully"];
}
}];
I changed little bit from your code. Change your path as #"me/feed". I hope, this may help you.
so I'm trying to post a photo on my Facebook page (I'm admin) from iPhone app. I'm using FB Sessions to create the session, get the read permission, get manage_pages permission, then, I successfully get my Facebook Pages app-ids as a result of
[FBRequestConnection startWithGraphPath:#"/me/accounts" completionHandler:^(FBRequestConnection *connection, id result, NSError *error)
{
NSLog(#"%#", [result description]);
}]; // have token, what now?
Which is still fine. Then, I try to post a photo to the app_id/photos feed, and it does not work = it uploads the photo correctly, but shows me (as in my profile) uploading the photo rather then the Page itself. What could be the problem?
Here's the code for the params and the call
NSDictionary *params = [NSDictionary
dictionaryWithObjects: [NSArray arrayWithObjects:
[UIImage imageNamed:#"Icon.png"],
#"This is my first photo post from xcode app", nil]
forKeys:[NSArray arrayWithObjects:
#"source",
#"message", nil]];
[FBRequestConnection startWithGraphPath:#"MyPageID/photos" parameters:params HTTPMethod:#"POST" completionHandler:^(FBRequestConnection *connection, id result, NSError *error)
{
NSLog(#"%#", [result description]);
} ];
the [result description] log from the call is fine (it returns the id = xx and "post_id" = yy, which I assume are correct), as is the call itself - the only problem is that it shows me as the author, and not the Page itself.
MyPageID is correct, because calling
NSDictionary *paramsFeed = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:#"This is my first page post from xcode app", nil] forKeys:[NSArray arrayWithObjects:#"message", nil]];
[FBRequestConnection startWithGraphPath:#"390106241058188/feed" parameters:paramsFeed HTTPMethod:#"POST" completionHandler:^(FBRequestConnection *connection, id result, NSError *error)
{
NSLog(#"result: %#", [result description]);
}];
Also, calling me/photos and posting the photo there with dictionaryKey #"picture" works, and it posts the photo on my own wall perfectly.
Do anyone knows where the problem could be hidden?
I found the solution, although I find it weird that I did not have to do this for the /feed page update
Huge thanks goes for Mr. Arpit Kumar Kulshrestha, who pointed out the right way in my previous incarnation of the problem ( Xcode - how to share photo from iPhone app to Facebook managed page feed )
the solution:
I've tried setting a new FBSession before, but it still had a lot of errors in it, so I've left that route and went to another one. However, it makes perfect sense to do that -
create FBAccessTokenData, which has the Page's token in it, and set other things to the same as the active session - like this
FBAccessTokenData *tokenData = [FBAccessTokenData createTokenFromString:pageTokenString permissions:[FBSession activeSession].accessTokenData.permissions expirationDate:[FBSession activeSession].accessTokenData.expirationDate loginType:FBSessionLoginTypeFacebookApplication refreshDate:nil];
then, one need to create a new FBSession, and what is important, it needs to have set its tokenCacheStrategy to something without data, i.e.[FBSessionTokenCachingStrategy nullCacheInstance] . I did a blank allocation ([[FBSession alloc] init]), and that gave me a lot of errors, however when I use this one
FBSession *sessionFb = [[FBSession alloc] initWithAppID:appID permissions:[NSArray arrayWithObjects: #"publish_stream", #"manage_pages", nil] urlSchemeSuffix:nil tokenCacheStrategy:[FBSessionTokenCachingStrategy nullCacheInstance]];
it works perfectly. And when you have this new session, you want to open the path for the data to come and go, and you can make it like this:
[sessionFb openFromAccessTokenData:tokenData completionHandler:^(FBSession *session, FBSessionState status, NSError *error)
{
}];
and the last part before it starts working correctly is setting the activeSession to this newly allocated and opened session, this way:
[FBSession setActiveSession:sessionFb];
after I've made all of these changes, the photo page sharing started to work magically.
However, I'm still not sure how is it possible that the photo share did not work before but the feed share did.. but this solves my issue.
