ios - didReceiveRemoteNotification 在单击通知(背景)时不工作，但在应用程序为前台时工作

Question

需要一些关于 PUSH Notifications 的解决方案。我从堆栈中尝试了不同的解决方案，但对我不起作用!

我的问题是当我从我的 触发通知时PHP 脚本 通知本身被触发。单击我想从我的应用程序导航到新 View 的通知的事情。

当应用程序在 中时后台模式并且单击通知对 没有任何作用完成处理程序警告 ，但当应用程序位于 事件状态并触发通知完成工作并导航到另一个 View
请恢复此问题，我附上了下面的代码。

在后台模式下单击通知时出错
警告:UNUserNotificationCenter 委托(delegate)收到了对 -userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler: 的调用，但从未调用过完成处理程序。

任何帮助表示赞赏

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],

                     fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        // If you are receiving a notification message while your app is in the background,

        let application = UIApplication.shared
        self.window = UIWindow(frame: UIScreen.main.bounds)
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let initialViewController = storyboard.instantiateViewController(withIdentifier: "LaunchScreenViewController")
        self.window?.rootViewController = initialViewController
        self.window?.makeKeyAndVisible()

        if let messageID = userInfo[gcmMessageIDKey] {

            print("Message ID: \(messageID)")

        }

        // Print full message.

        print(userInfo)

        print("Hello u have entered through Push  notification ")

        completionHandler(UIBackgroundFetchResult.newData)
    }

您好，我刚刚得到了答案的解决方案!
我尝试导航到 中的另一个 View usernotificationcenter 扩展方法它奏效了。

extension AppDelegate: UNUserNotificationCenterDelegate {
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        print("Entry through the Notification")

        let application = UIApplication.shared
        self.window = UIWindow(frame: UIScreen.main.bounds)
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let initialViewController = storyboard.instantiateViewController(withIdentifier: "stationListVC")
        self.window?.rootViewController = initialViewController
        self.window?.makeKeyAndVisible()

        if response.actionIdentifier == "remindLater" {
            let newDate = Date(timeInterval: 900, since: Date())
            scheduleNotification(at: newDate)
        }
    }
} 

感谢大家的帮助；)
