(swift) 初始视图控制器调用 tableview 控制器而不点击任何按钮

Question

我已尝试使用以下代码执行此操作。但是，它不起作用。

警告：尝试呈现不在窗口层次结构中的视图！

有什么方法可以在不点击按钮的情况下调用其他视图控制器？

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    let configuration = WKWebViewConfiguration()
    let controller  =  WKUserContentController()
    controller.addScriptMessageHandler(self, name: "JSListener")
    configuration.userContentController = controller

    let webview = WKWebView(frame: self.view.frame, configuration: configuration)
    let url = NSBundle.mainBundle().URLForResource("index1", withExtension: "html")
    let request = NSURLRequest(URL: url!)

    self.view = webview
    webview.loadRequest(request)

     let secondViewController:UIViewController = OurTableViewController()
    self.presentViewController(secondViewController, animated: true, completion: nil)
}

尝试移动

let secondViewController:UIViewController = OurTableViewController()
self.presentViewController(secondViewController, animated: true, completion: nil)

像那样查看DidAppear

override func viewDidAppear(animated: Bool) {
    let secondViewController:UIViewController = OurTableViewController()
    self.presentViewController(secondViewController, animated: true, completion: nil)
}
