I am trying to add the "select friends" to my iOS app. I set up the login view. Once I login I open the friend picker but it comes up blank. I see the table with the done and cancel buttons but there are no friends loaded into the table.
- (IBAction)selectFriendsButtonAction:(id)sender {
if (self.friendPickerController == nil) {
// Create friend picker, and get data loaded into it.
self.friendPickerController = [[FBFriendPickerViewController alloc] init];
self.friendPickerController.title = #"Select Friends";
self.friendPickerController.delegate = self;
}
[self.friendPickerController loadData];
[self.friendPickerController clearSelection];
[self presentViewController:self.friendPickerController animated:YES completion:nil];
}
Prior to opening the friend picker controller ensure your Facebook session is active by calling this:
if (!FBSession.activeSession.isOpen) {
// if the session is closed, then we open it here, and establish a handler for state changes
[FBSession.activeSession openWithCompletionHandler:^(FBSession *session,
FBSessionState state,
NSError *error) {
// Handle error
}];
}
There's two things you need to take care of that you may well not realize you need even if you understand the rest of the Facebook SDK pretty well.
The dialog will only show friends that have also installed the app.
You have to ask for the user_friends permission during your login flow.
For 1., create or use a test user you already have and run your app with that user in order to authorize the app for basic access ("install" it).
For 2, add that permission to your login flow, log out and back in with the sender you're testing (probably your own user), and if you don't get prompted to grant it even then, uninstall the app via https://www.facebook.com/settings/?tab=applications.
http://www.brianjcoleman.com/tutorial-get-facebook-friends-in-swift/ discusses some of this. The Facebook docs themselves either don't mention the 2 issues at all or it's buried.
If you use "FBFriendPickerViewController", it seems return friends who also use this APP. In Facebook document: after API Graph v2.0, "me/friends" will only return friends that also use the app. I think that's why the friend table is blank.
There is another option that you can use "FBTaggableFriendPickerViewController" instead. But your APP will need to be reviewed by Facebook before it can get data back. (https://developers.facebook.com/docs/graph-api/reference/v2.2/user/taggable_friends?locale=zh_TW)

I need to implement game invitations (ie. inviting friends who are not users of the app to try the app) on an iOS app (which already has a working Facebook login system). There seems to be several possible ways of doing this, each with their own different requirements. FBSDKGameRequestDialog seems like a promising way of doing this. The tutorial at https://developers.facebook.com/docs/games/services/gamerequests says:
"Alternatively, by specifying app_non_users, the sender will only see friends who have previously not authenticated the app. This should be used when using requests for inviting new users to the game."
This seems to be exactly what I'm looking for. I therefore tried this:
FBSDKGameRequestContent* content = [[FBSDKGameRequestContent new] autorelease];
content.actionType = FBSDKGameRequestActionTypeSend;
content.filters = FBSDKGameRequestFilterAppNonUsers;
content.message = #"something";
content.title = #"something";
content.objectID = #"1"; // No idea what to put here
FBSDKGameRequestDialog* dialog = [[FBSDKGameRequestDialog new] autorelease];
dialog.content = content;
dialog.delegate = self;
NSError* error = nil;
if(![dialog validateWithError: &error])
NSLog(#"%#", error);
else
[dialog show];
The dialog launches, but calls the delegate with an error, namely:
Error Domain=com.facebook.sdk.share Code=100 "(null)" UserInfo={com.facebook.sdk:FBSDKErrorDeveloperMessageKey=Invalid fbid.}
That error message is not very helpful, nor can I find anywhere why it's happening, or what the exact requirements are for this to be possible. (Yes, I am logged successfully into Facebook. Everything else is working just fine. I have no idea where that "Invalid fbid" is coming from.)
The same tutorial page offers an alternative to do this, by requesting a list of invitable friends explicitly, and using your own GUI. However, it says:
"This feature is only available to games with a presence on Facebook Desktop"
Obviously it doesn't bother telling what that means, or give a link to further information. And of course making the request doesn't work. (The error says "please set a Canvas URL in your app's settings", which I have no idea what it means or how to do it, even after browsing Facebook's own documentation and googling.)
Either way, I would prefer the SDK's own dialog for this, as it's much less work.
objectId refers to the "Open Graph object ID of the object being sent.". Lets say I am sending you 100 Coins of your in-app currency, then this would be the ID of the object you created for that "gift".
You don't have to provide a value for it if you are not planning to send around in-game items, and in your example, 1 is obviously not a valid ID for an object. The message could be more descriptive though.
After being able to create a small iOS app that logs in to Facebook. I would like this app to get the user’s list of friends.
Though I browsed the internet for a while and tried various approach I did not succeed to get what I wanted.
In the viewDidLoad method I use this code to start with:
loginView = [[FBLoginView alloc] initWithReadPermissions:#[#"user_friends"]];
And then I implement the loginViewFetchedUserInfo: user: method this way:
- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
user:(id<FBGraphUser>)user
{
[FBRequestConnection startWithGraphPath:#"/me/friends"
parameters:nil
HTTPMethod:#"GET"
completionHandler:^(
FBRequestConnection *connection,
id result,
NSError *error
) {
NSLog(#“Result: %#",result);
}];
}
When I execute the app I get this result:
Result: {
data = (
);
summary = {
"total_count" = 267;
}; }
But what I really want is a list of the friends with their names …etc…
All the things I tried for that didn’t work. Though I suppose the solution must be simple.
I also used code like this in the method above ….. but with no luck:
NSArray* friends = [result objectForKey:#"data"];
One more point, here https://developers.facebook.com/docs/graph-api/reference/v2.1/user/friends one can read:
This will only return any friends who have used (via Facebook Login)
the app making the request.
But the result I get (267) does not match this statement. It (267) is the number of friends the user has on Facebook, which is in fact what I am interested in.
I hope someone has something to say to put me on the right track and make things clearer.
Since Facebook's 2.x SDK upgrade they have tightened up access to information in the "Open Graph API."
Under Permissions That Do Not Require Review
App friends. This optional permission grants your app the ability to read a list of friends who also use your app.
You get automatic access to any friends that already use your app (per its Facebook ID.)
You will have to request Extended Permissions if you want to access the list of all a user's friends. That means going through Facebook's App Review process which can be quite challenging (and annoying.)
Frankly, I am not even sure that it is possible to use the new Open Graph API to get the user's entire friend list.
I have an iPhone app that is used for taking photos. I just finished adding the Facebook sharing functionality to this app.
I went through this entire page here: https://developers.facebook.com/docs/ios/open-graph
I followed all of the instructions, and copied and pasted the code into xcode. The only thing I didn't do was the one part at the very bottom of the page called "Deep Linking", but that is not important right now.
After doing all of this, my app can successfully share an image to facebook. However, it is not being shared the way I need it to.
When I go to my facebook page to see the share, you would never even know it's there. I have to scroll almost half way down the page, and then it's in the bottom left corner.
Here is a screenshot showing where the share is located on my facebook page when viewed on a Desktop computer:
And here is how the share looks when using the Facebook App for the iPhone (I blacked out my name):
These both look terrible. Here are 2 examples of what I want to accomplish.
Here is how a photo from this app called "Frontback" looks when I share it to my page and view on a Desktop computer:
And it looks the same on the Facebook App for the iPhone as well.
The only difference I can tell is that the URL for my shares has "/activity/" in it, where as the Frontback app shares have "photo.php" in their Facebook URL's.
I can't figure out how to get my app's shares to look like the shares from the Frontback app.
Any help is greatly appreciated thank you.
The posts that you created seems meaningful to me. An open-graph feed is always beautiful and more meaningful than the normal feed.
What Frontback post you are seeing is simple photo upload, that's not a feed. I mean it all depends on your requirement, what exactly your app will want to do.
If you just want to show some photos via your app like Frontback, you can avoid open graph and publish photos using the API \POST /photos.
But if you want to give a link that could redirect the user to the app you should use what you are using right now.
Another thing, when you said-
When I go to my facebook page to see the share, you would never even know it's there. I have to scroll almost half way down the page, and then it's in the bottom left corner.
That's the beauty of open-graph, it clubs all the activities of an app in your timeline, not unnecessarily making status updates and flooding your timeline. The stories appear on top in your/your friends wall and the ticker. You can also see the actual story by clicking on the time in the story of your activity log-
(activity log)
(actual story)
- (void)requestPermissionAndPost {
[FBSession.activeSession requestNewPublishPermissions:[NSArray arrayWithObjects:#"publish_actions", #"publish_checkins",nil]
defaultAudience:FBSessionDefaultAudienceEveryone
completionHandler:^(FBSession *session, NSError *error) {
if (!error) {
// Now have the permission
[self postOpenGraphAction];
} else {
// Facebook SDK * error handling *
// if the operation is not user cancelled
if (error.fberrorCategory != FBErrorCategoryUserCancelled) {
[self presentAlertForError:error];
}
}
}];
}
- (void)postOpenGraphAction
{
FBRequestConnection *newConnection = [[FBRequestConnection alloc] init];
FBRequestHandler handler =
^(FBRequestConnection *connection, id result, NSError *error) {
// output the results of the request
[self requestCompleted:connection forFbID:#"me" result:result error:error];
};
UIImage *img = imageView.image;
NSString *message = [NSString stringWithFormat:#"%# %# #DealsHype",msg.text,hashtagFromStore];
FBRequest *request=[[FBRequest alloc] initWithSession:FBSession.activeSession graphPath:#"me/photos" parameters:[NSDictionary dictionaryWithObjectsAndKeys:UIImageJPEGRepresentation(img, 0.7),#"source",message,#"message",#"{'value':'EVERYONE'}",#"privacy", nil] HTTPMethod:#"POST"];
[newConnection addRequest:request completionHandler:handler];
[self.requestConnection cancel];
self.requestConnection = newConnection;
[newConnection start];
}
this is the good to upload image with some message .. if you want to upload a big image like Frontback
I have created a custom open graph object, action and story on Facebook developer website, then followed the tutorial to be able to post it through the official FB app (without login in the app). This is the code:
NSMutableDictionary<FBGraphObject> *object;
NSString *returnUrl = [NSString stringWithFormat:#"http://tettomante.it/questions?%#",
[NSString stringWithURLParams:#{#"answer": _answerLabel.text, #"divination": [self divinationNickname]}]];
object = [FBGraphObject openGraphObjectForPostWithType:#"boobs-teller:question"
title:_questionTextView.text
image:#"https://d1rdorpdffwq56.cloudfront.net/icona_tettomante.jpg"
url:returnUrl
description:_answerLabel.text];
NSMutableDictionary<FBOpenGraphAction> *action = (NSMutableDictionary<FBOpenGraphAction> *) [FBGraphObject openGraphActionForPost];
action[#"question"] = object;
// Check if the Facebook app is installed and we can present the share dialog
FBOpenGraphActionShareDialogParams *params = [[FBOpenGraphActionShareDialogParams alloc] init];
params.action = action;
params.actionType = #"boobs-teller:ask";
params.previewPropertyName = #"question";
// If the Facebook app is installed and we can present the share dialog
if([FBDialogs canPresentShareDialogWithOpenGraphActionParams:params]) {
// Show the share dialog
[FBDialogs presentShareDialogWithOpenGraphActionParams:params
clientState:nil
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
if(error) {
// There was an error
NSLog(#"Error publishing story: %#", error.description);
}
else {
// Success
NSLog(#"result %#", results);
}
}];
}
The problem is that once in the FB app the custom story preview appears correctly and after about 10 seconds disappears, while the "Publish" button on the top is disabled (greyed out) and doesn't enable itself. I don't understand what's going on. I thought that could be because the app was in sandbox mode (I was using the administrator user so that shouldn't have mattered), so I made it public but nothing changed. Then I thought I had to make FB review the custom action, so I had that sorted out also, but nothing has changed. Now I don't know what to try next.
I had the same issue while creating a new app. The Open Graph tags have to be exactly correct, or you won't be able to publish your story.
Check to make sure the objects and actions created in the Facebook app dashboard match what you have listed in the code.
object = [FBGraphObject openGraphObjectForPostWithType:#"boobs-teller:question"
In this line, "boobs-teller" should be what you have listed as your App's namespace(Facebook Apps > Settings > Basic), and "questions" should be the custom Object (Open Graph > Object Types) you created in the App dashboard. If you haven't created these yet, go here: https://developers.facebook.com/apps
params.actionType = #"boobs-teller:ask";
In this line, "boobs-teller" should be your app namespace, and "ask" is the custom Action (Open Graph > Action Types) you created in the app dashboard.
More details are here: https://developers.facebook.com/docs/ios/open-graph/
You can also check the sample iOS apps on GitHub, the FBOGSampleSD app helped me out a lot while learning Open Graph. https://github.com/fbsamples/ios-howtos
I am trying out adding facebook integration in an app using the new (beta) facebook ios sdk 3.0. All I would like to is post a status update to facebook. I used a FBLoginView to login to facebook. I put my app id in the plist as instructed on facebook. I put in some code to post to facebook.
(void)viewDidLoad
{
[super viewDidLoad];
NSArray *perms;
perms = [NSArray arrayWithObjects:#"status_update", nil];
FBLoginView *loginview =
[[FBLoginView alloc] initWithPermissions:perms];
loginview.frame = CGRectOffset(loginview.frame, 5, 5);
loginview.delegate = self;
[self.view addSubview:loginview];
// Do any additional setup after loading the view, typically from a nib.
}
- (IBAction)poststatus:(UIButton *)sender {
NSString *message = [NSString stringWithFormat:#"Test staus update"];
[FBRequestConnection startForPostStatusUpdate:message
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
[self showAlert:message result:result error:error];
}];
}
- (void)showAlert:(NSString *)message
result:(id)result
error:(NSError *)error {
NSString *alertMsg;
NSString *alertTitle;
if (error) {
alertMsg = error.localizedDescription;
alertTitle = #"Error";
} else {
NSDictionary *resultDict = (NSDictionary *)result;
alertMsg = [NSString stringWithFormat:#"Successfully posted '%#'.\nPost ID: %#",
message, [resultDict valueForKey:#"id"]];
alertTitle = #"Success";
}
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:alertTitle
message:alertMsg
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertView show];
}
The odd thing is, this code works ONCE. After authenticating the user for the first time, I can post ONE status update successfully. After that, all subsequent attempts will fail with a FBiOSSDK error 5 (in the console, Error: HTTP status code:400). The only way to fix this is to remove the app from the facebook account and re-authenticate. I'm not sure what the problem is. I looked online for solutions but couldn't find anything. If anyone knows how to fix this, please let me know. Thanks
com.facebook.sdk error 5 is always irritating while working with Facebook iOS sdk. Most of the times it comes with addional in console Error: HTTP status code:400. Its a perception that there is a bug in Facebook iOS sdk that produces this error randomly. I think this error occurs for some certain reasons and sdk do not provide actual reason of error when it occurs.
Several Possible Reasons
Every request in sdk is accomplished with completion blocks that we actually pass as argument in completionHandler. This error occurs when a block is in progress and made another request. A simple example might be If you have written request to post on Facebook (startForPostStatusUpdate::) on some button action. On single button tap it would work fine but if you double tap on button it will throw this error com.facebook.sdk error 5
If you are trying to post when your current session is not opened. e.g. Once sign in with Facebook then kill the app then reopen and then try to share on Facebook, Result -> com.facebook.sdk error 5. In this case try to reopen session using
Facebook do not allow same status to be posted repeatedly, they think it might be some kind of spam e.g. If you are trying to update status and you have hard coded a string lets say #”This is a test status update” you are posing again and again. After 5 to 10 attempts they wont allow you to do anymore. Resulting com.facebook.sdk error 5. If this is the scenario you should change your status string and try updating.
Facebook has defined a limit for a particular user to post status using sdk. e.g If you are trying to update status and you have done lets say 15 to 20 status updates. They wont let you do more Resulting -> com.facebook.sdk error 5. In this scenario try to unauthorize the app from your Facebook account and reauthorize it OR try using other Facebook account
It seems there might be no answer to the issue. I have checked FB samples coming with SDK, in these examples also the same error happens. So it means after few status updates (15-20) Facebook reaches limits for that particular user. If you log-out for that user and log-in as another user, you can successfully post.
If I will find any extension to limit settings I will reply.
Also Facebook doesn't allow for the same Post.
Use a proxy !
FB ios SDK is just a wrap to an HTTP request to graph.facebook.com/....?access_token=.....
So you can easily replicate the request or use an HTTP proxy to see the real server answer (which is not error 5 !).
