iOS Share link trough Facebook with social.framework

[kikko088]

I want to share a link on the user's wall with social.framework, if I try to do it with my account (admin of facebook app) and with device there isn't any problem, If I try to do it with simulator I get this error:

code = 190; 
message = "The access token was invalidated on the
device."; type = OAuthException;

while if I try with another account I get this error:

Error Domain=XPCObjectsErrorDomain Code=2 "The operation couldn’t be
completed. (XPCObjectsErrorDomain error 2.)"
This is the code:

ACAccountStore *accountStore = [[ACAccountStore alloc] init];

    ACAccountType *facebookAccountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

    NSDictionary *options = @{ACFacebookAppIdKey : @"xxxxx",
                              ACFacebookPermissionsKey : @[@"email", @"publish_stream"],
                              ACFacebookAudienceKey:ACFacebookAudienceFriends};

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

            NSArray *accounts = [accountStore accountsWithAccountType:facebookAccountType];

            NSDictionary *parameters = @{@"message" : @"Prova anche tu xxx!",
                                         @"link": @"https://www.facebook.com/pages/"};
            NSURL *URL = [NSURL URLWithString:@"https://graph.facebook.com/me/feed"];

            SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                                    requestMethod:SLRequestMethodPOST
                                                              URL:URL
                                                       parameters:parameters];

            [request setAccount:[accounts lastObject]];

            [request performRequestWithHandler:^(NSData *respData, NSHTTPURLResponse *urlResp, NSError *error) {
                NSDictionary *responseDictionary = [NSJSONSerialization JSONObjectWithData:respData
                                                                                   options:kNilOptions
                                                                                     error:&error];
                NSLog(@"Response %@", responseDictionary.allValues);
            }];
            }
        else {
            NSLog(@"Accesso in scrittura negato %@", error);
        }
    }];
