Question

我想在单击通知并关闭应用程序时推送UIViewController

以下是我在didReceiveRemoteNotification中的代码

if application.applicationState == .inactive || application.applicationState == .background {
        DeeplinkHandler.handleNotification(userNotification: userNotification)
        completionHandler(UIBackgroundFetchResult.newData)
    }

以下是用于处理通知深层链接的代码

class func handleNotification(userNotification :  UserNotification?){
    let appDelegate = UIApplication.shared.delegate as! AppDelegate
    var navigationVC = UINavigationController()

    if let tabBarVC = appDelegate.window?.rootViewController as? UITabBarController {
        if let navVC = tabBarVC.viewControllers?[tabBarVC.selectedIndex] as? UINavigationController {
            navigationVC = navVC
        }
        else {
            tabBarVC.selectedIndex = 0
            navigationVC = tabBarVC.viewControllers?[0] as! UINavigationController
        }

    }
   // let navigationVC = appDelegate.window?.rootViewController as! UINavigationController

    switch userNotification?.type ?? "" {
    case DeeplinkHandler.NOTIF_TYPE_WEBVIEW:
        let appWebView = AppStrings.appStoryBoard.instantiateViewController(withIdentifier: "webPageViewControllerID") as! WebPageViewController
        appWebView.url = userNotification?.url ?? ""
        navigationVC.pushViewController(appWebView, animated: true)
    //case DeeplinkHandler.NOTIF_TYPE_PAGE_ID:
    //case DeeplinkHandler.NOTIF_TYPE_FLIGHT_STATUS:
    default:
        let appWebView = AppStrings.appStoryBoard.instantiateViewController(withIdentifier: "notificationViewControllerID") as! NotificationViewController
        //appWebView.url = userNotification?.url ?? ""
        navigationVC.pushViewController(appWebView, animated: true)

    }
}

但是当应用程序关闭时，单击通知时单击通知会导致崩溃。

如何处理？

在 didFinishLaunchingWithOptions

中尝试了以下代码

 var notification: [AnyHashable: Any]? = (launchOptions?[UIApplication.LaunchOptionsKey.remoteNotification] as? [AnyHashable: Any])
    if let notification = notification {
        print("app received notification from remote\(notification)")
        var userNotification : UserNotification?
        if notification is [String : Any] {
            userNotification = createNSaveNotification(notification)
            DeeplinkHandler.handleNotification(userNotification: userNotification)
        }
    }
    else {
        print("app did not receive notification")
    }

这也会在应用程序关闭时在通知点击时使应用程序崩溃

Answer 1

应用关闭时，您必须检查方法

中的通知

--no-cache-dir

并检查launchOptions中的数据

当应用关闭时，iOS处理推送通知
