iPhone App can autolaunch after device boot?
Is it possible for an app to be brought to the front of the screen on system startup(i.e when the phone is switched on)? Similar to how android does the broadcast listener where you can bring the application to the front of the screen? Any examples if you can?
I am using models iPhone 3 and iPhone 4.
No this is not possible, all you can do is use notification ,local or push to bring an application to the front when unlocked.
There is no way to set an app as startup app when turning the system on.
