Question

我正在我的应用程序中集成firebase推送通知。在最新版本的iOS中它工作正常。但在低版本的iOS中我遇到了一些问题。

在低版本的iOS中，didReceiveRemoteNotification回调会在没有用户点击通知的情况下自动触发。

在低版本iOS中自动调用，无需用户点击通知

[AnyHashable("notification"): {
body = “body text”;
e = 1;
sound = default;
sound2 = default;
title = “title here”;
}, AnyHashable("from”):2343434, AnyHashable("a_data"): ****, AnyHashable("collapse_key"): com.***.****]

用户选中通知

后的最新iOS版本

[AnyHashable("a_data"):****, AnyHashable("aps"): {
alert =     {
    body = "body";
    title = "title";
};
sound = default;
}, AnyHashable("gcm.message_id"): ******]

这是我的代码

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,
    // this callback will not be fired till the user taps on the notification launching the application.

    // Print full message.
    print("user t \(userInfo)")

    completionHandler(UIBackgroundFetchResult.newData)
    print(userInfo)

    let aps = userInfo["aps"] as! [String: AnyObject]
    let alert = aps["alert"] as! [String: AnyObject]
    let eventTitle : String = alert["title"] as! String? ?? "Title"
    print(alert["title"] ?? "Title")

}

// This method will be called when app received push notifications in foreground
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)
{
    completionHandler([.alert, .badge, .sound])
}

希望你理解我的问题。如何解决这个问题呢？提前致谢
