You can flash them but there isn’t an option to make them always visible:

[ScrollView flashScrollIndicators];

UITableView is a subclass of UIScrollView,So you can use it directly with it

  - (void)viewDidAppear:(BOOL)animated {
      [super viewDidAppear:animated];
      [self.tableView performSelector:@selector(flashScrollIndicators) withObject:nil afterDelay:0];
}
