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];
}
Check out for more info : UIScrollView - showing the scroll bar
Swift:
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
self.tableView.flashScrollIndicators()
}
