iOS wkwebview https 加載不受信用的站點

iOS 9.0以上直接設置WKNavigationDelegate代理

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

　　引用一下

self.wk.navigationDelegate = self

　　搞定，成功加載證書錯誤的站點
