Facebook Login

Hello,

How can i know user loggedin succesfully at iPhone ? I've tried everything but couldn't make it ? I did this forceDialog = true at android but i want to use user details if the user entered all information at ios7 facebook section.

I don't want to use Facebook login and logout button.

Thanks
