In Swift use this,

Let's assume you wants to have pull to refresh in WebView,

So try this code:

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()
}

In Objective-C, I used this:

- (void)addPullToRefreshToWebView{
    UIColor *whiteColor = [UIColor whiteColor];
    UIRefreshControl *refreshController = [UIRefreshControl new];
    NSString *string = @"Pull down to refresh...";
    NSDictionary *attributes = @{ NSForegroundColorAttributeName : whiteColor };
    NSAttributedString *attributedString = [[NSAttributedString alloc] initWithString:string attributes:attributes];
    refreshController.bounds = CGRectMake(0, 0, refreshController.bounds.size.width, refreshController.bounds.size.height);
    refreshController.attributedTitle = attributedString;
    [refreshController addTarget:self action:@selector(refreshWebView:) forControlEvents:UIControlEventValueChanged];
    [refreshController setTintColor:whiteColor];
    [self.webView.scrollView addSubview:refreshController];
}

- (void)refreshWebView:(UIRefreshControl*)refreshController{
    [self.webView reload];
    [refreshController endRefreshing];
}
