Question

in my application on iphone when i call

[facebook authorize:permissions delegate:self];

the framework show login dialog automatically if i’m not loggedin, and then show permission dialog (This is great for the frist time that a user use the application).
But if i’ve aleady get permission i always show the dialog with message “You have aleady authorized this application”.

So, how can i login without show permission dialog? Or can i check if i’ve aleady get permission to the application?
In the framework sample code the only way to login is by authorize method…

Thanks in advance.

You could store the Access Token (make sure to request offline_access permission) locally on the device and next time the user uses your App check if the token’s still active (make a call to /me/permissions or something like that ) – if it is still active you don’t need to go back to Facebook to reauthenticate- if it isn’t, the current Login code you’re using should still be fine.
