Pull to refresh on WKWebview

Question

I'm trying to make a pull to refresh on WKWebView. When I try to pull and refresh, I get this error:'NSInvalidArgumentException', reason: '-[GoldenVillage.AvailabilityViewController mymethodforref:]: unrecognized selector sent to instance 0x111d18e50'

How to fix it?

My code in viewDidAppear :

self.availabilityWebview = WKWebView(
     frame: self.containerView.bounds,
     configuration: config
)
self.view = self.availabilityWebview!
refController.bounds = CGRectMake(0, 50, refController.bounds.size.width, refController.bounds.size.height) 
refController.addTarget(self, action: Selector(("mymethodforref:")), for: UIControlEvents.valueChanged)
refController.attributedTitle = NSAttributedString(string: "Pull to refresh")
availabilityWebview?.scrollView.addSubview(refController)

self.noNetwork.text! = ""
if let crew = user!["crew"] as? [String:Any], let crewID = crew["crew_id"] as? String {

let url = URL(string: "http://ec2-52-221-231-3.ap-southeast-1.compute.amazonaws.com/gv/available-schedule_3.php?id=\(crewID)")
self.availabilityWebview!.load(URLRequest(url:url!))


func mymethodforref(refresh:UIRefreshControl){
    availabilityWebview?.reload()
    refController.endRefreshing()
}
func webViewDidFinishLoad(_ webView: UIWebView) {
    UIApplication.shared.isNetworkActivityIndicatorVisible = false
}

func webViewDidStartLoad(_ webView: UIWebView) {
    UIApplication.shared.isNetworkActivityIndicatorVisible = true
}

instead of `Selector(("mymethodforref:")` try `#selector(mymethodforref(refresh:))` — 3stud1ant3, Sep 11 '17 at 08:19
@3stud1ant3 It worked! Can I ask another question? How to change the position of the refresh controller? I added the position code on answer but I get error. how to convert CGReactMake to CGReact? — Lester, Sep 11 '17 at 08:26
1) Post another question if you're stuck somewhere else. 2) it's `CGRect` — LinusGeffarth, Sep 11 '17 at 08:29

instead of
