将 xcode 6 更新为 7（代码无效 swift）

Question

我有一个带有一些 webView 的项目 swift（我正在使用 WKWebView）并且它没有任何问题。我将 xcode 更新到 7.1 版本，现在 none 我的 webview 工作。我没有错误，但我的屏幕上什么也没有。如果有人有想法谢谢

（对不起我的英语）

 class Actu: UIViewController, WKNavigationDelegate  {

/**** Variable declaration and IBoutlet *****/

    @IBOutlet weak var contact: UIBarButtonItem!
    var BackButtonItem:UIBarButtonItem!
    var rightplayBarButtonItem:UIBarButtonItem!
    var refreshPageButton:UIBarButtonItem!
    var webView: WKWebView
    var varIntermediate = String()
    let urlContainer = StreamPlayer.sharedInstance.url

/**** Javascript Insertion *****/

required init?(coder aDecoder: NSCoder){
    let config = WKWebViewConfiguration()
    let scriptURL = NSBundle.mainBundle().pathForResource("hideSectionsActu", ofType: "js")
    let scriptContent = try? String(contentsOfFile:scriptURL!, encoding:NSUTF8StringEncoding)
    let script = WKUserScript(source: scriptContent!, injectionTime: .AtDocumentStart, forMainFrameOnly: true)
    config.userContentController.addUserScript(script)
    self.webView = WKWebView(frame: CGRectZero, configuration: config)
    super.init(coder: aDecoder)
    self.webView.navigationDelegate = self
}
   ////////////////////////////////////////////////
   /**** View did Load *****/

override func viewDidLoad() {
    super.viewDidLoad()

    self.BackButtonItem = UIBarButtonItem(title: "Retour", style: UIBarButtonItemStyle.Plain, target: self, action: "back:")
    self.refreshPageButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Refresh, target: self, action: "refresh:")

    // Webview creation//
    webView.translatesAutoresizingMaskIntoConstraints = false
    view.addSubview(webView)
    webView.translatesAutoresizingMaskIntoConstraints = false
    let height = NSLayoutConstraint(item: webView, attribute: .Height, relatedBy: .Equal, toItem: view, attribute: .Height, multiplier: 1, constant: 0)
    let width = NSLayoutConstraint(item: webView, attribute: .Width, relatedBy: .Equal, toItem: view, attribute: .Width, multiplier: 1, constant: 0)
    view.addConstraints([height, width])

    webView.addObserver(self, forKeyPath: "loading", options: .New, context: nil)

    let url = NSURL(string: "MyURL")
    let request = NSURLRequest(URL: url!)
    webView.loadRequest(request)

}
///////////////////////////////////////////
func webViewFunction(webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {

}

func webView(webView: WKWebView, didFinishNavigation navigation: WKNavigation!) {

    let javaScriptString : NSString = "var el=document.getElementsByClassName(\"home-link\")[0];el.removeAttribute(\"href\");"

    webView.evaluateJavaScript(javaScriptString as String, completionHandler: nil)
}

这是我在 xcode 7

"conversion" 之后的代码

您应该注意以下2个提示：

1.Pay注意这个设置：

PROJECT/TARGETS -> Build Settings -> Build Options -> Embedded Content Contains Swift Code -> YES

2.In 你的 plist 文件，你应该添加：

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
    </dict>

如果您使用 Xcode 7 或更高版本重建项目，您可以请求非 https 互联网请求。
