Querying Facebook user data through new iOS6 social framework

Question

I am trying to query information about a user using iOS 6\'s new Facebook integration API. This is the code I\'m using, which is basically identical to what they demoed at W

Answer 1

OK here is how I do this integration with iOS 6 and get what I want from Facebook:

In AppDelegate I do this:

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
    return [FBSession.activeSession handleOpenURL:url];
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
    [FBSession.activeSession handleDidBecomeActive];
}

- (void)applicationWillTerminate:(UIApplication *)application
{
    [FBSession.activeSession close];
}

and in my ViewController where I want to retrieve information about myself or my friends I do this (NOTE: this is a test, so it is a lot of permissions!):

NSArray *permissions =
    [NSArray arrayWithObjects:@"email", @"user_location",
     @"user_birthday",
     @"user_likes", @"user_interests",@"friends_interests",@"friends_birthday",@"friends_location",@"friends_hometown",@"friends_photos",@"friends_status",
     @"friends_about_me", @"friends_birthday", @"friends_hometown", @"friends_interests", @"friends_likes", @"friends_location", nil];

    [FBSession openActiveSessionWithReadPermissions:permissions
                                       allowLoginUI:YES
                                  completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
                                      /* handle success + failure in block */
                                      if (status) {
                                          NSLog(@"Facebook Read Permission is successful!");
                                          [self presentPostOptions];

                                          //   [self presentPostOptions];


                                      }
                                  }];

Then in "presentPostOptions" I do this (in this example I try to retrieve something from my friend):

- (void)presentPostOptions
{

    [[FBRequest requestForMyFriends] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error)

     {

         if (!error) {

NSArray *data = [user objectForKey:@"data"];
             NSLog(@"%d", [data count]);
             for (FBGraphObject<FBGraphUser> *friend in data) {
                 NSLog(@"%@", [friend first_name]);
                 NSLog(@"%@", [friend last_name]);
                 NSLog(@"%@", [friend id]);
                 //make sure you have FBProfilePictureView outlet in your view
                 //otherwise skip the profile picture!
                 self.fbProfilePic.profileID = @"you'r friend's profile.id";

             }
         }
         else
         {
             NSLog(@"error");
             //  [self didFailWithError:error];
         }
     }];

I don't know what else you want to do because in your question you just tried to make a connection but this way you can do what ever you want while you are integrated in iOS 6.

One more thing, make sure about your App Settings over Facebook and the configs over there like enable your app for iOS and the ID for iPhone/iPad. Also the FacebookAppID in your plist.

Let me know if it works out for you,

EDIT: btw my Facebook SDK is 3.1.1.

Answer 2

I had the same error message, I fixed it by saving my account after renewing the credential.

Answer 3

add your active access token in paramete like

NSDictionary *parameters = [NSDictionary dictionaryWithObject:@"PUT_ACCESS_TOKEN_HERE" forKey:@"access_token"];

Answer 4

Make sure your (ACAccount *)facebookAccount (or in your case self.account) object is strong and you set it correctly while getting permissions.

Answer 5

The answer is simple

in viewDidLoad() use:

accountStore= [[ACAccountStore alloc]init];
facebookAccountType= [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

NSDictionary *options= @{
ACFacebookAudienceKey: ACFacebookAudienceEveryone,
ACFacebookAppIdKey: @"<YOUR FACEBOOK APP ID>",
ACFacebookPermissionsKey: @[@"public_profile"]

                          };    

[accountStore requestAccessToAccountsWithType:facebookAccountType options:options completion:^(BOOL granted, NSError *error) {

    if (granted) {
        NSLog(@"Permission has been granted to the app");
        NSArray *accounts= [accountStore accountsWithAccountType:facebookAccountType];
        facebookAccount= [accounts firstObject];
        [self performSelectorOnMainThread:@selector(facebookProfile) withObject:nil waitUntilDone:NO];

    } else {
        NSLog(@"Permission denied to the app");
    }
}];

And the function-(void)facebookProfile

NSURL *url = [NSURL URLWithString:@"https://graph.facebook.com/me"];

Notice the params you need are added as dictionary Refer below for complete list https://developers.facebook.com/docs/graph-api/reference/user

NSDictionary *param=[NSDictionary dictionaryWithObjectsAndKeys:@"picture,id,name",@"fields", nil];

SLRequest *profileInfoRequest= [SLRequest requestForServiceType:SLServiceTypeFacebook requestMethod:SLRequestMethodGET URL:url parameters:param];
profileInfoRequest.account= facebookAccount;


[profileInfoRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
    NSLog(@"Facebook status code is : %ld", (long)[urlResponse statusCode]);

    if ([urlResponse statusCode]==200) {

        NSDictionary *dictionaryData= [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableLeaves error:&error];



    } else {

    }
}];


}

Answer 6

I faced with the same issue and found the workaround:

NSString *uid = [NSString stringWithFormat:@"%@", [[self.account valueForKey:@"properties"] valueForKey:@"uid"]] ;                
NSURL *url = [NSURL URLWithString:[@"https://graph.facebook.com" stringByAppendingPathComponent:uid]];
