Project help needed ! LED's - BLuetooth - iOS - Arduino UNO

Hi all

First thanks for the interest in looking at my project post!

I'm relative new to programming and electronics so am seeking some help.

For my project I want to be able to control some adafruit RGB neopixels connected to my Arduino uno via Bluetooth on my iPad with a custom made application using Xcode.

Any ideas on what Bluetooth unit I should use ? Ive been looking at shields but not sure what would be best a shield or a stand alone Bluetooth moduel.

Would anyone be able to help with some basic codeing for the Arduino and on Xcode to get the two connected ?

Anyone got any experience with this ?

Also would it be much simpler to use a cable from the iPad to arduino ? I would prefer Bluetooth but if it's very complex it might be a little past me.

Thanks again!

Quick update I've decided to go with the adafruit Bluetooth LE
