拉动刷新抛出这个错误

Question

我正在尝试在我的云套件笔记应用程序中实现下拉刷新，但是当我下拉到运行刷新时出现以下错误：

我在 UITableview 的故事板中启用了刷新

在 ViewDidLoad()

中实施了以下内容

 self.refreshControl?.addTarget(self, action: "HandleRefresh:", forControlEvents: UIControlEvents.ValueChanged)

这是我的刷新方法：

    func handleRefresh(refreshControl: UIRefreshControl) {


    self.tableView.reloadData()
    refreshControl.endRefreshing()
}

行 self.tableView.reloadData() 在我的代码中的其他地方工作毫无价值。

当发生错误时 Xcode 可能在我的 AppDelegate class 的这一行结束时一文不值

class AppDelegate: UIResponder, UIApplicationDelegate, UISplitViewControllerDelegate {

Answer 1

评论者解决了问题

HandleRefresh 与 handleRefresh 方法和调用之间的拼写错误。

Answer 2

这个修复了我的问题：

refreshControl.addTarget(self, action:
        #selector(ViewController.HandleRefresh(sender:)),
                             for: UIControlEvents.valueChanged)

拉动刷新抛出这个错误
