iPhone - Do two apps using GPS share the same GPS data?
When an app calls for GPS data, does it activate the GPS call itself and
then when another app simultaneously running calls it does it make a
separate call? Or when the second app accesses the GPS does it get the
data that's already there (or something similar, like a channel is opened
in both apps which the GPS system sends all data to each channel when data
is available)?
I'm wondering, because if each app only gets control of the GPS half the
time it could certainly result in a less effective GPS. So I'm guessing
that the iPhone was built with this in mind and the same GPS data would be
available to each app, but I don't know if that's what's being done.
Anyone know? Thanks!
