停止提交PushNotification

Question

当我没有收到通知时,我不想提出userId通知userInfo.

那么如何才能停止通知呢？

我试过的代码:

  func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        print("willPresent notification")

        let aps = notification.request.content.userInfo[AnyHashable("aps")]!
        guard let data = aps as? [String: Any] else{ return}

        if let userId = data["userId"] as? String {
            completionHandler([.alert, .badge, .sound])
        }else{
            return
        }
    }

但仍然会显示通知.

试试这样吧

if let userId = data["userId"] as? String {
        completionHandler([.alert, .badge, .sound])
} else {
       completionHandler([])
}
