Currently, for iOS, I want to send title in multiple lines. How do I do this? I'm trying out using Firebase console to test. But nothing seems to work for me.

我尝试过这些

如

as suggested in this post. But nothing really worked.

我基本上希望通知的前两行以粗体显示.任何帮助，不胜感激.

I basically want the first 2 lines of the notification to be in bold. Any help much appreciated.

推荐答案

您看到的粗体第一行是通知标题，第二行是字幕，下面是内容(常规字体).

The 1st line in bold you see is a notification Title, the second the Subtitle, and the Content underneath (regular font).

这些是通知的属性，因为iOS 10在 UN(Mutable)NotificationContent 上进行了设置>(字幕行之前不可用).

These are properties of a notification, since iOS 10 set on UN(Mutable)NotificationContent (subtitle line is not available before).

可以在通过APNS发送的有效负载中配置它们的属性:

They properties can be configured in the payload sent via APNS:

{
  "aps": {
    "alert": {
      "title": "Custom title",
      "subtitle": "Custom subtitle",
      "body": "Custom message"
    }
  }
}

此外，您可以创建UserNotificationServiceExtension来更新已收到通知的上述属性.

Also, you can create a UserNotificationServiceExtension to update the above properties of a notification that has been received.
