Add Selfie Stick Support To iOS App

I am looking to add support for a "Selfie Stick Remote" to my upcoming iOS app. This question was already asked in the form of How to detect click event of connected Bluetooth peripheral device (Selfie stick)? but for Android, not iOS.

Specifically I am looking for it to work with the bluetooth devices (like this one http://ift.tt/1NnSiqf).
