c# - 使用 moon apns 设置内容可用

Question

引用此链接: http://www.objc.io/issue-5/multitasking.html我现在可以通过设置 content-available=1

在 iOS 上发送静默推送通知

我在 C# 上使用 moon apns 来发送推送通知，但是我找不到这个属性来发送静默推送(我正在使用开发证书)

下面是我的代码:

  string p12File = "test.p12";
  string p12FilePassword = "1234";
  bool sandbox = false;
  var push = new PushNotification(sandbox, p12File, p12FilePassword);
  NotificationPayload payload1;
  payload1 = new NotificationPayload(testDeviceToken, message, 0, "Silence.m4R");
  payload1.AddCustom("message", "HIDDEN");
  var notificationList = new List<NotificationPayload>() { payload1 };
  var rejected = push.SendToApple(notificationList);
  foreach (var item in rejected)
  {
     return false;
  }

知道如何使用 moon apns 发送这个:

{
"aps" : {
    "content-available" : 1
},
"content-id" : 42
}
