FBConnect: “The user hasn't authorized the application to perform this action”

Question

I m developing an iPhone app which includes facebook wall posting.After log in, I post to user\'s wall by following code:

NSString *appIcon = [NSString stringWit         


        

Answer 1

I have Found the solution of the problem by myself.

Actually the cause of the problem is the application doest have permission to "Post To Wall". (publish_stream).Hence FB was denying with following error.

"The user hasn't authorize this application to perform this action".

So when user logs in, Ask user to give permission of publish_stream,

- (void)session:(FBSession*)session didLogin:(FBUID)uid {

    FBPermissionDialog *permissions = [[FBPermissionDialog alloc]initWithSession:_session];
    permissions.permission = [NSString stringWithString: @"publish_stream"]; 
    [permissions show];

}

`
When once the user have allowed "Post to wall", this dialog wont appear ever again.
