use the following code to feed

  NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   [NSString stringWithFormat:@"YOUR MESSAGE"],
                                   @"message", nil];
    [facebook requestWithGraphPath:@"me/feed" andParams:params andHttpMethod: @"POST" andDelegate:self];
