256 bytes limitation

[n-studio]

Hi all,
I spent hours of debugging to find out that the notification didn't work because of the 256 bytes limitation.
It would be nice to raise an error when the payload exceeds 256 bytes.

Would a raise "Error" if message.to_json.size > 256 work in Notification.initialize(device_token, message) ?

iOS8 now supports 2KB of data per push message, so this is not as simple as it appears.

If possible, you should be using push to notify the client to fetch new data, not send the data in the push message itself. Hopefully this way you will never hit the 256 (or 2048 byte) limitation.

Oh, I didn't know for iOS8 new limitation.
I need to display a preview of the message in the notification panel so even if the app fetched the message afterwards a part of the message must be sent. As the other info (user ID, message id) have variable lengths, I think it's useful to get an access to the payload size in bytes.
