PathToGUID doesn't work on iOS64.

[mutoo]

Temporarily, I export GUIDs (File > export GUIDs…) and generate a HashMap that manually mapping event/bus name to guid. And It works:

FMODUnity.RuntimeManager.PlayOneShot (EventToGuid("event:/fire"));

so I don’t need Master.strings.bank now.

I have upgraded Unity3d to 5.3.4, and the problem solved.
