Image previews in Notification Center

Is it possible to add an image to a push notification's payload? I've seen it being done in the Photos & Messages apps. I was hoping this wasn't some private Apple API.

Solution

  • Is not possible

    According to the Push Notification Programming guide the payload max size should not exceed 256 Bytes:

    Documentation extract:

    Payload length—The length of the payload in network order (that is, big endian). The payload must not exceed 256 bytes and must not be null-terminated.

    Here´s the Apple Documentation link :
