how to lock Iphone by programmatically [duplicate]

Answer 1

You can't do this on a device that isn't jailbroken- Apple won't let you. Even if you did figure out a way to somehow do this, it would never pass the submission process. If you are developing for jailbroken devices, it's another story, but for the App Store, what you want is impossible.

Answer 2

You can not do this using flex or the iOS SDK. You can, however, enable AssistiveTouch by going into Settings -> General -> Accessibility -> AssistiveTouch which will put a little button on your screen that when tapped will allow you to lock your device

Answer 3

If you want to do this so, Apple never approve this, your app must be jailbreak. you can do this by calling Private framework on your project. you can use GraphicsServices.framework. note , this GraphicsServices.framework is a private framework. Apple never accept your app. By calling GSEventLockDevice() method you can lock your Iphone Device easily. This GSEventLockDevice() resides in the GSEvent.h. hope this one helps .
