userInfo 通知数据不可检索？

Question

所以我一直试图弄清楚为什么 userInfo 没有显示我想要的数据。 当我打印 userInfo 我得到这个：

[AnyHashable("aps"): {
    alert = "test account \ni'm running late";
    badge = 11;
    sound = "bingbong.aiff";
}]

但是，当我尝试执行 userInfo["alert"] 时，它返回 nil。我已经尝试了一切，包括userInfo["aps"]["alert"]，但仍然没有。我已经被困了好几个小时了。我希望有人能帮帮忙。

这是我的全部功能：

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
    //PFPush.handle(userInfo)
    if (userInfo["badge"] != nil) {
        let badgeNumber: Int = userInfo["badge"] as! Int
        application.applicationIconBadgeNumber = badgeNumber
    }
    if application.applicationState == .inactive {
        PFAnalytics.trackAppOpenedWithRemoteNotificationPayload(inBackground: userInfo, block: nil)
    } else if application.applicationState == .active {
        let notificationManager = LNRNotificationManager()
        notificationManager.showNotification(title: "Test", body: "", onTap: { () -> Void in
            notificationManager.dismissActiveNotification(completion: { () -> Void in
                print("Notification dismissed")
            })
        })
        print(userInfo)
        NotificationCenter.default.post(name: NSNotification.Name(rawValue: "didRecieveNotificationWhileInApp"), object: nil)
    }
}

正如您在 userInfo 转储中看到的那样，badge 在字典中的键 aps

if let aps = userInfo["aps"] as? [String:Any] {
  let badgeNumber = aps["badge"] as! Int
  application.applicationIconBadgeNumber = badgeNumber
}
