ios - 应用程序未运行/应用程序终止时如何处理推送通知

Question

我正在使用 Firebase 通知。当 applicationState 处于后台时，它工作正常。但是，当应用程序未运行/终止时，未调用 func getPushNotiData(_ notification: NSNotification)

在appDelegate文件中实现NotificationCenter来处理dashView中的通知

func application(_ application: UIApplication, didReceiveRemoteNotification 
userInfo: [AnyHashable : Any]) {
NotificationCenter.default.post(name: NSNotification.Name(rawValue: 
"getPushNotificationData"), object: nil, userInfo: userInfo)
}

如果应用程序未运行/终止在 didFinishLaunchingWithOptions 委托(delegate)方法中实现 NotificationCenter

 if (launchOptions != nil)
    {
        let userInfo = launchOptions![.remoteNotification] as? [AnyHashable: Any]
        if userInfo != nil {
        NotificationCenter.default.post(name: NSNotification.Name(rawValue: "getPushNotificationData"), object: nil, userInfo: userInfo)
        }
    }

在 dashView 中处理 NotificationCenter

override func viewDidAppear(_ animated: Bool) {
    NotificationCenter.default.addObserver(self, selector: #selector(self.getPushNotiData(_:)), name: NSNotification.Name(rawValue: "getPushNotificationData"), object: nil)
}

@objc func getPushNotiData(_ notification: NSNotification){
    if let url = notification.userInfo!["url"] as? String {
        let destination = storyboard?.instantiateViewController(withIdentifier: "NotificationDlsViewController") as! NotificationDlsViewController
        destination.notiUrl = url
        self.navigationController?.pushViewController(destination, animated: true)
}
}

如果应用程序未运行(已终止状态)，您无法执行任何方法或代码，只有当用户单击推送通知时，您才能在 didFinishLaunchingWithOptions launchingOptions 中接收它的对象并处理它....
