I have been using WKWebView.
I would like to work javascript on iOS9+Swift 2.0. But It couldn't work.
console.log("hoge") couldn't even work.
My code is here

import UIKit
class CommonWebVCL: GABase,UIWebViewDelegate,UIScrollViewDelegate,WKNavigationDelegate,WKUIDelegate {
var webview: WKWebView!
var str_url:String! = ""
var url:String!
var gobackSearch:Bool! = false
var previousScrollViewYOffset:CGFloat? = 0
var toolbarheight:CGFloat = 0
var analytics_category:String!
override func viewDidLoad() {
super.viewDidLoad()
changeUserAgent()
let webViewConfiguration = WKWebViewConfiguration()
self.webview = WKWebView(frame: self.view.bounds, configuration: webViewConfiguration)
self.webview.navigationDelegate = self
self.webview.UIDelegate = self
addObserverForWKWebView()
self.view.addSubview(webview)
setBackButton()
}
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
navigationBarInit()
/
self.webview.scrollView.delegate = self
}
func setBackBtnForWeb(){
let leftbtn = UIButton(frame: CGRect(x: 0, y: 0, width: 48, height: 22))
leftbtn.setImage(UIImage(named: "back_btn"), forState: .Normal)
leftbtn.addTarget(self, action: "goBackForWeb:", forControlEvents: UIControlEvents.TouchUpInside)
let backButton = UIBarButtonItem(customView: leftbtn)
self.navigationItem.setLeftBarButtonItem(backButton, animated: true)
}
func webView(webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!){
/
if let tmpstr_url = self.webview.URL?.absoluteString{
if (tmpstr_url.rangeOfString("tel") == nil){
SVProgressHUD.show()
}
}
}
func webView(webView: WKWebView, didFinishNavigation navigation: WKNavigation!){
/
if SVProgressHUD.isVisible(){
SVProgressHUD.dismiss()
}
}
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
navigationBarInit()
let URL = NSURL(string: url)
let urlRequest: NSURLRequest = NSURLRequest(URL: URL!)
self.webview.loadRequest(urlRequest)
}
override func viewDidLayoutSubviews() {
self.webview.frame = self.view.bounds
navigationBarInit()
}
override func viewDidDisappear(animated: Bool) {
super.viewDidDisappear(animated)
if SVProgressHUD.isVisible(){
SVProgressHUD.dismiss()
}
if (self.gobackSearch != nil){
sendEvent(analytics_category, str_action: "back")
self.navigationController?.popViewControllerAnimated(true)
}
self.webview.scrollView.delegate = nil
self.webview.navigationDelegate = nil
self.webview.stopLoading()
UIApplication.sharedApplication().networkActivityIndicatorVisible = false
}
func addObserverForWKWebView(){
self.webview.addObserver(self, forKeyPath: "canGoBack", options: NSKeyValueObservingOptions.New, context: nil) /
self.webview.addObserver(self, forKeyPath: "URL", options: NSKeyValueObservingOptions.New, context: nil) /
}
/
override func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject?, change: [String : AnyObject]?, context: UnsafeMutablePointer<Void>) {
if object!.isEqual(webview){
if keyPath == "estimatedProgress"{
self.navigationController?.setSGProgressMaskWithPercentage(Float(self.webview.estimatedProgress*100))
navigationBarInit()
}else if keyPath == "canGoBack"{
}else if keyPath == "URL"{
if let tmpstr_url = self.webview.URL?.absoluteString{
self.str_url = tmpstr_url
handleUrl()
}
}
}
}
/
func handleUrl(){
}
/
deinit{
if self.webview != nil{
/
self.webview.removeObserver(self, forKeyPath: "canGoBack", context: nil)
self.webview.removeObserver(self, forKeyPath: "URL", context: nil)
}
}
@IBAction func goBackForWeb(sender: AnyObject) {
if self.webview.canGoBack{
webview.goBack()
}else{
self.navigationController?.popViewControllerAnimated(true)
}
}
func webViewDidStartLoad(webView: UIWebView){
SVProgressHUD.showWithStatus("読み込み中")
navigationBarInit()
}
func webViewDidFinishLoad(webView: UIWebView){
SVProgressHUD.dismiss()
}
func webView(webView: UIWebView, didFailLoadWithError error: NSError?){
SVProgressHUD.dismiss()
}
func webView(webView: WKWebView, runJavaScriptAlertPanelWithMessage message: String, initiatedByFrame frame: WKFrameInfo, completionHandler: () -> Void){
let alertController = UIAlertController(title: frame.request.URL?.host, message: message, preferredStyle: .Alert)
alertController.addAction(UIAlertAction(title: "OK", style: .Default, handler: { action in
completionHandler()
}))
self.presentViewController(alertController, animated: true, completion: nil)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
/
}
}What is this problem?
By the way this problem is only iOS9 by swift2.0.
It works correctly on other platform including iOS9 by swift 1.2.
