从AppDelegate在WkWebView中打开url

Question

我有一个url(通过OneSignal通知(，我想在我的ViewController.webView(WkWebView(中加载该url。我怎样才能做到这一点？我必须将webView设为静态变量吗？

// 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!))
}

Answer 1

写下您的控制器名称，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)
}
}

或者试试这个。

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中使用以下内容访问它。

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!))
}

在AppDelegate中：

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
}
}
}
}
