Hi all,
I've recently been experimenting with handling location updates with AIR on iOS. I'm using a native extension to register for region monitoring and all is working fine while the application is running (either in the foreground or background).
I'm having an issue with background startup of the AIR app, ie handling the case when the application isn't running, having being terminated either via the user or the OS. The iOS docs say:
In iOS, regions associated with your app are tracked at all times, including when the app isn’t running. If a region boundary is crossed while an app isn’t running, that app is relaunched into the background to handle the event.
And this appears to happen, however the AIR application doesn't seem to be able to start in this mode. I can see the application attempt to start and then crash on the main application thread:
Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Subtype: KERN_INVALID_ADDRESS at 0x0000000000000001

Has anyone had any success in getting this to work or am I looking at a limitation of AIR here ? chris.campbell any ideas?
Cheers
