openActiveSessionWithPublishPermissions show login form twice

Question

I'm trying to implement post wall using objective-c but when i do request new permission to 'publish_actions' with action session, the FB SDK login form is show again.

I'm looking for this tutorial: https://developers.facebook.com/docs/ios/publish-to-feed-ios-sdk/

In my application flow is basically this:

void (^completionHandler)(FBSession*, NSError*) = ^(FBSession*session, NSError*error){

    if (session.isOpen && !error)
    {
        [FBWebDialogs presentFeedDialogModallyWithSession:session
                                               parameters:params
                                                  handler:handler];
    }
};

// abrie o dialog
BOOL isFBIntegration = [SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook];

if ([FBSession.activeSession.permissions indexOfObject:@"publish_actions"] == NSNotFound)
{
    if(isFBIntegration)
    {
        [[FBSession activeSession] requestNewPublishPermissions:@[@"publish_actions"]
                                                defaultAudience:FBSessionDefaultAudienceFriends
                                              completionHandler:completionHandler];
    }
    else
    {
        [FBSession openActiveSessionWithPublishPermissions:@[@"publish_actions"]
                                           defaultAudience:FBSessionDefaultAudienceEveryone
                                              allowLoginUI:YES
                                         completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
                                             completionHandler(session, error);
                                         }];
    }
}
else
{
    completionHandler(FBSession.activeSession, nil);
}

The user is already logged in because I do ask him to log when it enters the application:

HOME

    [FBSession openActiveSessionWithReadPermissions:@[@"basic_info, user_friends, friends_interests"]
                                       allowLoginUI:YES
                                  completionHandler:nil];

When Facebook is native integration, all right, but when no, openActiveSessionWithPublishPermissions show login form again.

thank you.

Facebook iOS SDK 3.1 has now disabled openActiveSessionWithPublishPermissions. You will need to first establish a read only session, then additionally request write permissions. You can read more details about the upgrade process at iOS SDK Upgrade Guide.
