Is it possible to shutdown an iOS device (iPhone, iPad, iPod) with objective c? I have searched the internet through and through, and nothing at all has come up. I was just thinking about it, how much control over the device you really have. Does anyone know if this is possible? If so, how?
No, it's not possible in a non-"jailbroken" state. Your app cannot escape it's own "sandbox" and consequently has no access to system calls that could be used to control the power state of the device.
Not only that, but App Store approval chances for this feature would be slim to none.
