Creating OSC templates

So Im trying to create a custom iphone template for OSC
anyone tried this ?
Im trying to work out how it knows whats what
I have been using the ipad template and copying the text I.E : fader/1 , choose/1 and so on as im imagining that text format is how it ID's function
will this work??
also when adding a fader V it always starts with the fader at the top so I imagine you just invert it and give it values of 0-255 ?
Im flying blind as I have no desk to test on at the mo
cheers
