Create a WKWebView in a UIView - ios

Question

I'm trying to add a WKWebView inside of a UIView ,
The code seems to work fine ( the page is loaded the bounds is good the delegate print the message with no error)
but the View (called ViewForStuffInWeb ) stay blank, nothing in it
can someone explain why ?
import UIKit
import WebKit
class ViewController: UIViewController ,WKNavigationDelegate {
#IBOutlet var ViewForStuffInWeb: UIView!
var webView = WKWebView()
let request = "https://www.google.fr"
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
self.automaticallyAdjustsScrollViewInsets = false
let config = WKWebViewConfiguration()
webView = WKWebView(frame: ViewForStuffInWeb.bounds ,configuration : config)
webView.navigationDelegate = self
ViewForStuffInWeb = webView
println("webview : frame :\(webView.frame) , bounds : \(webView.bounds)")
requesting(request)
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
func requesting (request :String) {
if let url = NSURL(string: request) {
webView.loadRequest(NSURLRequest(URL: url))
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func webView(webView: WKWebView, decidePolicyForNavigationAction navigationAction: WKNavigationAction, decisionHandler: (WKNavigationActionPolicy) -> Void) {
println("decide policy action")
decisionHandler(WKNavigationActionPolicy.Allow)
}
func webView(webView: WKWebView, decidePolicyForNavigationResponse navigationResponse: WKNavigationResponse, decisionHandler: (WKNavigationResponsePolicy) -> Void) {
println("decide policy response")
decisionHandler(WKNavigationResponsePolicy.Allow)
}
func webView(webView: WKWebView, didCommitNavigation navigation: WKNavigation!) {
println("commit navigation")
}
func webView(webView: WKWebView, didFailNavigation navigation: WKNavigation!, withError error: NSError) {
println("fail in didFailNavigation \(error)")
}
func webView(webView: WKWebView, didFailProvisionalNavigation navigation: WKNavigation!, withError error: NSError) {
println("fail in didFailProvisionalNavigation \(error)")
}
func webView(webView: WKWebView, didFinishNavigation navigation: WKNavigation!) {
println("finish navigation")
}
thanks for reading

Answer 1

You never add the WKWebView to the view hierarchy. In your viewDidAppear, which code should really move to viewDidLoad, you probably want to replace:
ViewForStuffInWeb = webView
with:
ViewForStuffInWeb.addSubview(webView)
Although it is unclear what ViewForStuffInWeb actually is. The above will only work if that view exists in your nib and if it is connected.
