Question

以前，我使用以下代码来区分应用启动时通知是本地通知还是远程通知

    func application(_ application: UIApplication, 
    didFinishLaunchingWithOptions launchOptions: 
    [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    if (launchOptions?[UIApplication.LaunchOptionsKey.localNotification] != nil)
    {


    }
    if (launchOptions?[UIApplication.LaunchOptionsKey.remoteNotification] != nil)
    {


    }
    }

条件是我的应用程序被杀，我正在从通知中打开它。

问题在于此方法

if (launchOptions?[UIApplication.LaunchOptionsKey.localNotification] != nil)
{


}

从通知中心打开应用程序时，

已过时，并且不调用以下方法

 func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {}

Answer 1

您也可以在userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler:中查看通知类型，

类层次结构是：

UNNotificationResponse> UNNotification> UNNotificationRequest> UNNotificationTrigger

UNNotificationRequest中有四种类型的触发器：

UNLocationNotificationTrigger
UNPushNotificationTrigger
UNTimeIntervalNotificationTrigger
UNCalendarNotificationTrigger

只需使用

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    if response.notification.request.trigger is UNPushNotificationTrigger {
        print("remote notification");
    }

}

Answer 2

在创建本地通知时，在通知中设置标识符，可用于识别处理通知中的差异

以下是使用标识符创建本地通知的示例。

        let content = UNMutableNotificationContent()
        content.title = "Title"
        content.body = "Body"
        content.sound = UNNotificationSound.default()

        let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false)

        let request = UNNotificationRequest(identifier: "TestIdentifier", content: content, trigger: trigger)
        UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)

处理带有标识符的本地通知。

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    if response.notification.request.identifier == "TestIdentifier" {
        print("handling notifications with the TestIdentifier Identifier")
    }

    completionHandler()

}

对于处理远程通知，您可以使用以下行

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    print("handling notification")
    if let notification = response.notification.request.content.userInfo as? [String:AnyObject] {
        let message = parseRemoteNotification(notification: notification)
        print(message as Any)
    }
    completionHandler()
}
 
private func parseRemoteNotification(notification:[String:AnyObject]) -> String? {
    if let aps = notification["aps"] as? [String:AnyObject] {
        let alert = aps["alert"] as? String
        return alert
    }
 
    return nil
}

您可以通过检查第一个标识符来添加其他条件，以同一方法处理两个通知行。

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    print("handling notification")
 if response.notification.request.identifier == "TestIdentifier" {
        print("handling notifications with the TestIdentifier Identifier")
    }else {
    if let notification = response.notification.request.content.userInfo as? [String:AnyObject] {
        let message = parseRemoteNotification(notification: notification)
        print(message as Any)
    }
}
    completionHandler()
}
 
private func parseRemoteNotification(notification:[String:AnyObject]) -> String? {
    if let aps = notification["aps"] as? [String:AnyObject] {
        let alert = aps["alert"] as? String
        return alert
    }
 
    return nil
}

Answer 3

您可以在content.userInfo中设置本地通知键值。

content.userInfo = ["isMyLocationNotification" : true] //you can set anything

然后签入UNUserNotificationCenterDelegate的didReceive响应方法：

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
            print(response.notification.request.content.userInfo) //you can check your notification types
        }

在输出部分，您将通过isMyLocationNotification键使用Information数据，现在您可以确定天气通知是远程本地的。
