用wkwebview加載網(wǎng)絡(luò)地址,一直提示這個問題

斷點(diǎn)奔潰到Uiviewcontroller loadviewifrequired

但是也找不到原因,在plist文件加了所有的域名或者ip地址還是,最后把所有的代理方法全部打log.找到問題

 @available(iOS 8.0, *)
    func webView(_ webView: WKWebView, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Swift.Void)
    {
         XLLog(message: "")
        let cred = URLCredential.init(trust: challenge.protectionSpace.serverTrust!)
        completionHandler(.useCredential, cred)
        
    }
