UIRefreshControl in any UIScrollView

Apple documentation only explains how to use an UIRefreshControl in an UITableViewController, but what do you do if you want to add it to any UIScrollView?

UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];
[refreshControl addTarget:self action:@selector(handleRefresh:) forControlEvents:UIControlEventValueChanged];
[self.scrollView addSubview:refreshControl];
