Question

I am using Parse mobile platform to post a feed on facebook timeline. This is what they said in their docs : Note that if you already have the Facebook SDK installed in your app, our version of the Facebook SDK will happily work alongside it.

Take a look here.
The Parse SDK includes the entire Facebook SDK. All the classes are namespaced with PF_ to avoid conflicts with existing libraries. So, for example, the main Facebook object class in our SDK is PF_Facebook.

This one works perfectly using Facebook SDK :

- (IBAction)postFacebook:(UIButton *)sender {    
    self.postParams =
    [[NSMutableDictionary alloc] initWithObjectsAndKeys:
     @"https://developers.facebook.com/ios", @"link",
     @"https://developers.facebook.com/attachment/iossdk_logo.png", @"picture",
     @"Facebook SDK for iOS", @"name",
     @"Here we go", @"message",
     @"Build great social apps and get more installs.", @"caption",
     @"The Facebook SDK for iOS makes it easier and faster to develop Facebook integrated iOS apps.", @"description",
     nil];

    [FBRequestConnection startWithGraphPath:@"me/feed" parameters:self.postParams HTTPMethod:@"POST"
     completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
        [self showAlert:@"Link is posted" result:result error:error];
     }];
}

But when I use PF_FBRequestConnection, it does not work:

[PF_FBRequestConnection startWithGraphPath:@"me/feed" parameters:params HTTPMethod:@"POST"
        completionHandler:^(PF_FBRequestConnection *connection, id result, NSError *error) {
            [self showAlert:@"Link is posted" result:result error:error];
    }];

The error in the console:

Error: HTTP status code: 403

The thing is I could post a photo or Status using Parse, but not a link as you see.

I appreciate for any help.

The problem was the version of Parse framework that I was using. You can check it out here also.

For example this one did not supported on that version (1.1.12) :

[PF_FBSession.activeSession handleDidBecomeActive];

In the new version (1.1.13) problem is solved. So I could have this method:

// Convenience method to perform some action that requires the "publish_actions" permissions.
- (void) performPublishAction:(void (^)(void)) action {
    // we defer request for permission to post to the moment of post, then we check for the permission
    if ([PF_FBSession.activeSession.permissions indexOfObject:@"publish_actions"] == NSNotFound) {
        // if we don't already have the permission, then we request it now
        [PF_FBSession.activeSession reauthorizeWithPublishPermissions:[NSArray arrayWithObject:@"publish_actions"]
            defaultAudience:FBSessionDefaultAudienceFriends completionHandler:^(PF_FBSession *session, NSError *error) {
                if (!error) {
                    action();
                }
            //For this example, ignore errors (such as if user cancels).
        }];
    } else {
        action();
    }
}

And use it in this way:

[self performPublishAction:^{
        [PF_FBRequestConnection startWithGraphPath:@"me/feed" parameters:self.postParams HTTPMethod:@"POST"
            completionHandler:^(PF_FBRequestConnection *connection, id result, NSError *error) {
                [self showAlert:@"Link is posted" result:result error:error];
        }];
    }];
