UIRefreshControl不执行操作

Question

So I have enabled refreshing for the table view in Storyboard and put this code into the viewDidLoad() : 因此，我在Storyboard中启用了表视图的刷新，并将此代码放入viewDidLoad（）中：

refreshControl?.addTarget(self, action: #selector(ViewController.refresh(sender:)), for: .valueChanged)

and this is the refresh function: 这是刷新功能：

func refresh(sender: AnyObject) {
    print("a")
    self.tableView.reloadData()
    refreshControl?.endRefreshing()
}

The problem is that when I pull to refresh, it does not print "a"(put this for testing) and it does not end refreshing. 问题是，当我拉动刷新时，它不会打印“ a”（将此用于测试）并且不会结束刷新。 Why? 为什么？

Answer 1

Since you're already using Storyboards, try connecting your refresh control through IBActions (valueChanged) and see if it works. 由于您已经在使用Storyboards，请尝试通过IBActions（valueChanged）连接刷新控件，然后查看它是否有效。 Follow this link for a guide 点击此链接获取指导
