Question

How it possible to change color of overlapp tableview in child veiw controller.Here is the code but not working.......

  @interface ChatViewController : SOMessagingViewController

     -(void)viewWillAppear:(BOOL)animated{
          SOMessagingViewController *obj=[[SOMessagingViewController alloc]init];
          obj.tableView.backgroundColor =[UIColor redColor];

         }

Answer 1

You do not need to create a new instance of SOMessagingViewController.

Simply change your code to:

- (void)viewWillAppear:(BOOL)animated {
    self.tableView.backgroundColor = [UIColor redColor];
}

Since your ChatViewController class extends SOMessagingViewController, you have access to all of the public members directly.
