通过pubnub从android发送推送通知到ios

Question

我正在尝试使用android app从pubnub发送推送通知到ios app。我正在使用以下json作为推送通知消息，它​​适用于Android但不适用于ios：

 {
    "pn_gcm": {
        "message": "test message",
        "message_id": 1464707948327,
        "sender_id": "5735b2a2a3c4c3fe01d37600",
        "chat_room": "",
        "message_type": "text",
        "date": 1464707948327,
        "file_url": "",
        "sender_name": "Sorocean Alexei"
    },
    "pn_apns": {
        "aps": {
            "payload": {
                "message": "test message",
                "message_id": 1464707948327,
                "sender_id": "5735b2a2a3c4c3fe01d37600",
                "chat_room": "",
                "message_type": "text",
                "date": 1464707948327,
                "file_url": "",
                "sender_name": "sender name"
            },
            "alert": "sender name: test message",
            "badge": 1,
            "sound": "default"
        }
    }
 }
