I got the sollution. No need to check the session if we are logged in with facebook account.. Just post what u want

FBSession *session = [[FBSession alloc] init];

NSLog(@"FBSESSION %@", session);

if (session.state == FBSessionStateCreatedTokenLoaded || session.state == FBSessionStateOpen )
{

    [[[[iToast makeText:@"Post on wall success"] setGravity:iToastGravityBottom] setDuration:iToastDurationShort]show];
    // even though we had a cached token, we need to login to make the session usable
    [session openWithCompletionHandler:^(FBSession *session,
                                         FBSessionState status,
                                         NSError *error) {
        [FBSession setActiveSession:session];
        [FBRequestConnection startWithGraphPath:@"/me/feed"
                                     parameters:params
                                     HTTPMethod:@"POST"
                              completionHandler:^(FBRequestConnection *connection, id result, NSError *error){
                                  NSLog(@"error-- %@",error);
                              }];
    }];
}

Previously my code is like this shown in the above

I just added else part to the above code it will work correctly.My issue will resolved.

else
{

[[[[iToast makeText:@"Post on wall success"] setGravity:iToastGravityBottom] setDuration:iToastDurationShort]show];
[FBRequestConnection startWithGraphPath:@"/me/feed"
                             parameters:params
                             HTTPMethod:@"POST"
                      completionHandler:^(FBRequestConnection *connection, id result, NSError *error){
                          NSLog(@"error-- %@",error);
                      }];
}
