对于拉刷新，我正在使用

DGElasticPullToRefresh

https://github.com/gontovnik/DGElasticPullToRefresh

安装

豆荚的DGElasticPullToRefresh

import DGElasticPullToRefresh

然后把这个函数放到你的swift文件中，然后从你的

override func viewWillAppear(_ animated: Bool)

     func Refresher() {
      let loadingView = DGElasticPullToRefreshLoadingViewCircle()
      loadingView.tintColor = UIColor(red: 255.0/255.0, green: 255.0/255.0, blue: 255.0/255.0, alpha: 1.0)
      self.table.dg_addPullToRefreshWithActionHandler({ [weak self] () -> Void in

          //Completion block you can perfrom your code here.

           print("Stack Overflow")

           self?.table.dg_stopLoading()
           }, loadingView: loadingView)
      self.table.dg_setPullToRefreshFillColor(UIColor(red: 255.0/255.0, green: 57.0/255.0, blue: 66.0/255.0, alpha: 1))
      self.table.dg_setPullToRefreshBackgroundColor(self.table.backgroundColor!)
 }

不要忘记在视图消失时删除引用

要删除拉刷新，请将此代码放入您的

重写func viewDidDisappear(_ animated: Bool)

override func viewDidDisappear(_ animated: Bool) {
      table.dg_removePullToRefresh()

 }

看起来就像

快乐编码:)

在Swift中使用这个，

如果你想在WebView中刷新，

所以试试这段代码:

override func viewDidLoad() {
    super.viewDidLoad()
    addPullToRefreshToWebView()
}

func addPullToRefreshToWebView(){
    var refreshController:UIRefreshControl = UIRefreshControl()

    refreshController.bounds = CGRectMake(0, 50, refreshController.bounds.size.width, refreshController.bounds.size.height) // Change position of refresh view
    refreshController.addTarget(self, action: Selector("refreshWebView:"), forControlEvents: UIControlEvents.ValueChanged)
    refreshController.attributedTitle = NSAttributedString(string: "Pull down to refresh...")
    YourWebView.scrollView.addSubview(refreshController)

}

func refreshWebView(refresh:UIRefreshControl){
    YourWebView.reload()
    refresh.endRefreshing()
}

你可以使用tableView的子类:

import UIKit

protocol PullToRefreshTableViewDelegate : class {
    func tableViewDidStartRefreshing(tableView: PullToRefreshTableView)
}

class PullToRefreshTableView: UITableView {

    @IBOutlet weak var pullToRefreshDelegate: AnyObject?
    private var refreshControl: UIRefreshControl!
    private var isFirstLoad = true

    override func willMoveToSuperview(newSuperview: UIView?) {
        super.willMoveToSuperview(newSuperview)

        if (isFirstLoad) {
            addRefreshControl()
            isFirstLoad = false
        }
    }

    private func addRefreshControl() {
        refreshControl = UIRefreshControl()
        refreshControl.attributedTitle = NSAttributedString(string: "Pull to refresh")
        refreshControl.addTarget(self, action: "refresh", forControlEvents: .ValueChanged)
        self.addSubview(refreshControl)
    }

    @objc private func refresh() {
       (pullToRefreshDelegate as? PullToRefreshTableViewDelegate)?.tableViewDidStartRefreshing(self)
    }

    func endRefreshing() {
        refreshControl.endRefreshing()
    }

}

1 -在接口构建器改变类你的tableView PullToRefreshTableView或创建一个PullToRefreshTableView编程

在你的视图控制器中实现PullToRefreshTableViewDelegate

当表视图开始刷新时，tableViewDidStartRefreshing(tableView: PullToRefreshTableView)将在视图控制器中被调用

4 -调用yourTableView.endRefreshing()来完成刷新

这就是我如何使用Xcode 7.2让它工作的，我认为这是一个主要的错误。我在我的UITableViewController中使用它在viewWillAppear中

refreshControl = UIRefreshControl()
refreshControl!.addTarget(self, action: "configureMessages", forControlEvents: .ValueChanged)
refreshControl!.beginRefreshing()

configureMessages()

func configureMessages() {
    // configuring messages logic here

    self.refreshControl!.endRefreshing()
}

正如你所看到的，我必须在设置我的UIRefreshControl之后调用configureMessage()方法，随后的刷新将正常工作。

我构建了一个RSS提要应用程序，在其中我有一个Pull To refresh功能，它最初有上面列出的一些问题。

但是为了补充上面用户的答案，我到处寻找我的用例，但没有找到它。我正在从网络(RSSFeed)下载数据，我想下拉我的故事tableView来刷新。

上面提到的内容涵盖了正确的领域，但人们遇到了一些问题，以下是我所做的，它很有效:

我采取了@Blankarsch的方法，去了我的主。然后选择表视图来使用刷新，然后没有提到的是创建IBOutlet和IBAction来有效地使用刷新

//Created from main.storyboard cntrl+drag refresh from left scene to assistant editor @IBOutlet weak var refreshButton: UIRefreshControl override func viewDidLoad() { ...... ...... //Include your code ...... ...... //Is the function called below, make sure to put this in your viewDidLoad //method or not data will be visible when running the app getFeedData() } //Function the gets my data/parse my data from the web (if you havnt already put this in a similar function) //remembering it returns nothing, hence return type is "-> Void" func getFeedData() -> Void{ ..... ..... } //From main.storyboard cntrl+drag to assistant editor and this time create an action instead of outlet and //make sure arguments are set to none and note sender @IBAction func refresh() { //getting our data by calling the function which gets our data/parse our data getFeedData() //note: refreshControl doesnt need to be declared it is already initailized. Got to love xcode refreshControl?.endRefreshing() }

希望这能帮助到和我处境相同的人
