iPhone audio calls

[Paul Hibbert]

As with most things in LiveCode there are many ways to tackle most problems, I haven't done any mobile development yet, but I assume the custom properties work the same, if so a quick fix for this could be to use a custom property that is set to true on preOpenStack and then check that custom property at each command, something like...

--Stack Script
on preOpenStack
    if the environment is "mobile" then set the cMobile of this stack to "true"
end preOpenStack

on closeStack
    set the cMobile of this stack to empty // avoids the stack being saved with the custom property set to true
end closeStack
--

then your command could be…

--Control script
if the cMobile of this stack then iPhoneSetSoundChannelVolume "Ch_1","80"
--

You could fix most of this with a find & replace for the whole stack by finding "iPhoneSetSoundChannelVolume" and replacing with "if the cMobile of this stack then iPhoneSetSoundChannelVolume"

I'm not saying this is the best approach, but it should work and is very quick and easy to implement or remove.
