openActiveSessionWithPublishPermissions show login form twice

openActiveSessionWithPublishPermissions show login form twice

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.
