IL2CPP - RPC doesn't work

I'm using Unity 4.6.2p2 and as far as i see i can't make work the RPC functions. I've just created a simple project with a NetworkView in a GameObject and a simple script with some functions to create a server and to connect to it. In editor works with no problem but when i test it with a iOS device i get this error:

Internal RPC error. Invalid RPC index, function not registered.

This same project works perfectly in MONO, are RPCs incompatibles in IL2CPP? Is anyone having this issue too?

Thanks for the help ;) Regards.
