收到通知时的默认声音和振动

编程问答 2022-08-22

问题描述

我正在尝试向我的ios应用发送推送通知。该设备可以成功接收推送通知，我正在尝试同时接收声音和振动。收到通知后，它只是保持沉默。

在我的应用代理中，我试图添加

   func application(_ application: UIApplication,didReceiveRemoteNotification userInfo: [AnyHashable : Any],fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    print("serInfo=",userInfo)
    if UIApplication.shared.applicationState == .active {
      AudioServicesPlaySystemSound(SystemSoundID(kSystemSoundID_Vibrate))
        
    }
    else if UIApplication.shared.applicationState == .background {
        AudioServicesPlaySystemSound(SystemSoundID(kSystemSoundID_Vibrate))
    }
}

，但通知仍通过静默发出。有没有办法实现默认的声音和振动？

我也已经有

   func attemptToRegisterForNotifications(application: UIApplication) {

  if #available(iOS 10.0,*) {
      // For iOS 10 display notification (sent via APNS)
      UNUserNotificationCenter.current().delegate = self

      let authOptions: UNAuthorizationoptions = [.alert,.badge,.sound]
      UNUserNotificationCenter.current().requestAuthorization(
        options: authOptions,completionHandler: {_,_ in })
    
    } else {
      let settings: UIUserNotificationSettings =
      UIUserNotificationSettings(types: [.alert,.sound],categories: nil)
      application.registerUserNotificationSettings(settings)
    }

   // application.registerForRemoteNotifications()
}

设置，以便用户已经同意接收振动和声音。

var payload = {
  notification: {
    title: userThatSent.name + ' sent you a message',body: message.text
    "sound" : "default"

     }
   };

添加以上内容后，我会在终端中收到以下问题。

Error: Error occurred while parsing your function triggers.
