}

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {

return [facebook handleOpenURL:url]; 
}

This is my methods for calling facebook dialog boxes.But every time when i click to score for publishing;The permission box came first.I need to give permission after that the publish dialog box comes.I want to give permission ones and i want it to save it;after saving it i don’t wanna see the permission box ever again.How can i do it?What is wrong with my code?

edit:
My access token and expiration date is null i guess thats because of this.

Answer 1

A few things to check, you call the method login handling method “fbdidLogin” instead of fbDidLogin. This is case sensitive.

Make sure in your view controller header file that you added FBSessionDelegate as one of the protocols you support. That could be a reason fbDidLogin is not called. You could always add an NSLog to verify that the fbDidLogin method is reached.
