Question

I’m having troubles using the facebook binding from here ( https://github.com/mono/monotouch-bindings/tree/master/facebook ) and the problem is that the authorize ( login ) function doesn’t work on the device. On the simulator it’s working perfect, but from the device instead of the webbrowser login window it launches the official facebook app ( installed on the phone ).

The same thing happens with the sample provided with the binding.

Any ideeas how can I use the browser to login ( if I unninstall the official facebook app it works ok on the device also ) instead of the facebook app?

The code I use:

class SessionDelegate : FBSessionDelegate
{
    AppDelegate container;
    NSAction onLogin;

    public NSAction OnLogin {
        get {
            return this.onLogin;
        }
        set {
            onLogin = value;
        }
    }       

    public SessionDelegate (AppDelegate container)
    {
        this.container = container;
    }

    public override void DidNotLogin (bool cancelled)
    {
        Console.WriteLine("did not login");
        //container.SaveAuthorization ();
        if( OnLogin != null ) OnLogin.Invoke();
    }

    public override void DidLogin ()
    {
        Console.WriteLine("login !");
        container.SaveAuthorization ();
        if( OnLogin != null ) OnLogin.Invoke();
    }

    public override void DidLogout ()
    {
        Console.WriteLine("logout !");
        container.ClearAuthorization();
    }
}

And:

var sessionDelegate = new SessionDelegate (this); 
facebook            = new Facebook (LocalSettings.FacebookAppId, sessionDelegate);
var defaults = NSUserDefaults.StandardUserDefaults;
if (defaults ["FBAccessTokenKey"] != null && defaults ["FBExpirationDateKey"] != null)
{
         facebook.AccessToken    = defaults ["FBAccessTokenKey"] as NSString;
         facebook.ExpirationDate = defaults ["FBExpirationDateKey"] as NSDate;
}

and for login:

facebook.Authorize(new string [] { "email", "publish_stream", "read_friendlists", "user_photos" });

Okay, so I found the answer myself. The problem was in the facebook developer app settings, the iOS Bundle ID didn’t was the same with the one in monodevelop identifier 🙂
