Cannot login on Facebook on iPad with Facebook SDK

Question

I have a project on Unity 4.6 where I need to integrate sharing and leader-boards. I successfully added this functionality and in the Unity editor it works fine; I can share the results on my wall in Facebook.

However, when I try to do this on my iPad, Safari shows a message that I already have been authorized for this application, with 2 buttons - "Cancel" and "OK".

When I press the "OK" button, it then displays "Open this page in 'App name'" which puzzles me. Pressing "OK" again returns me back to the application and nothing happens.

I attached my logs (from Xcode) when pressing my "Share" or "Leaderboards" buttons.

What version of the Facebook Unity SDK are you using? This may be resolved in the latest release: 7.2.2 — zzzzzz

Seems like i made wrong my social scripts. I tried to make this with my template classes and this problem disappeared

    private void OnFbLogin()
{
    FB.Init(OnInitComplete, OnHideUnity);
}

private void OnInitComplete()
{
    if (FB.IsLoggedIn == false)
    {
        FB.Login();
    }

}

private void OnHideUnity(bool isGameShown)
{
    Debug.Log("Is game showing? " + isGameShown);
}

private void OnPost()
{
    Debug.Log("start posting");
    FB.Feed(
           linkCaption: "Test",
           linkName: "LinkName",
           linkDescription: "LinkDescription",
           picture: "",
           link: ""
           );
}

After this in xCode i got a new problem:

NSURLSession/NSURLConnection HTTP load failed

And i found the solution in this topic:

NSURLSession/NSURLConnection HTTP load failed on iOS 9

After that it worked
