Answer 1

APNS will not provide any Feedback for Push Notification. So we need to use a Silent Push Notification by make use of content-available property in aps dictionary. As we require a Normal Notification, we must put alert, sound, or badge payload in the aps dictionary. So that The Push Notification will visible to the User. As we are using content-available property in payload, iOS wakes up our app in the background so that we can send Delivery Report to our Web Server.

Sample Payload:

    {
        "aps" : {
            "alert" : "Sample Push Notification.",
            "badge" : 2,
            "sound" : "sound.aiff"
            "content-available" : "1"
        }
    }
