如何发布One Signal通知的附加数据并接收该数据？

您将data字段设置为传递给字典的键,OneSignal.postNotification如下所示.

OneSignal.postNotification(["contents": ["en": "Test Message"],
                            "include_player_ids": ["3009e210-3166-11e5-bc1b-db44eb02b120"],
                            "data": ["postID": "id"]])

然后,你需要准备好你的钥匙从additionalData来自payload于handleNotificationAction功能.

if let additionalData = payload?.additionalData {
   let postID: String? = additionalData["postID"]
}
