我有一个网址（通过OneSignal通知），我想在我的ViewController.webView（WkWebView）中加载网址 . 我怎样才能做到这一点？我必须使webView成为静态变量吗？

// AppDelegate
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    let onesignalInitSettings = [kOSSettingsKeyAutoPrompt: false]

    let notificationOpenedBlock: OSHandleNotificationActionBlock = { result in
        // This block gets called when the user reacts to a notification received
        let payload: OSNotificationPayload = result!.notification.payload

        if payload.additionalData != nil {
            let additionalData = payload.additionalData
            if additionalData?["url"] != nil {
                let url = additionalData?["url"]
                print("url: \(url)")
                // How to Open this URL?
            }
        }
    }
}

// ViewController
var webView: WKWebView!

override func viewDidLoad() {
    super.viewDidLoad()

    view.frame = view.bounds

    let webConfiguration = WKWebViewConfiguration()

    webView.navigationDelegate = self
    webView.uiDelegate = self

    view.addSubview(webView)

    let myURL = URL(string: "")
    webView.load(URLRequest(url: myURL!))
}

    编写控制器名称而不是“YourControllerVC”

    var appdelgateObj = UIApplication.shared.delegate as! AppDelegate
    if let destinationVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: “YourControllerVC”) as? YourControllerVC {
        if let window = appdelgateObj.window , let rootViewController = window.rootViewController {
            var currentController = rootViewController
            while let presentedController = currentController.presentedViewController {
                currentController = presentedController
            }
            destinationVC.webURL = "yourWebViewURLFromNotification"
            currentController.present(destinationVC, animated: true, completion: nil)
        }
    }

    或试试这个 .

    func redirectToWebView() {
    let mainStoryboard : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    let initialViewController: YourControllerVC = mainStoryboard.instantiateViewController(withIdentifier: "YourControllerVC") as YourControllerVC
    initialViewController.webURL = "yourWebViewURLFromNotification"
    self.window = UIWindow(frame: UIScreen.main.bounds)
    self.window?.rootViewController = initialViewController
    self.window?.makeKeyAndVisible()
}

    在AppDelegate中获取一个变量，并在ViewController中使用以下参数访问它 .

    In ViewController:

    var webView: WKWebView!

override func viewDidLoad() {
    super.viewDidLoad()

    view.frame = view.bounds

    let webConfiguration = WKWebViewConfiguration()

    webView.navigationDelegate = self
    webView.uiDelegate = self

    view.addSubview(webView)

    //Get the url from AppDelegate here
    let appDelegate = UIApplication.shared.delegate as! AppDelegate
    let url = appDelegate.myUrl

    let myURL = URL(string: url)
    webView.load(URLRequest(url: myURL!))
}

    In AppDelegate:

    var myUrl: String = "" //Create iVar here

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    let onesignalInitSettings = [kOSSettingsKeyAutoPrompt: false]

    let notificationOpenedBlock: OSHandleNotificationActionBlock = { result in
        // This block gets called when the user reacts to a notification received
        let payload: OSNotificationPayload = result!.notification.payload

        if payload.additionalData != nil {
            let additionalData = payload.additionalData
            if additionalData?["url"] != nil {
                let url = additionalData?["url"]
                print("url: \(url)")
                // Here save the url
                myUrl = url
            }
        }
    }
}
