how activate/desactivate the "slide to unlock" on iphone?

All is in the question, i would know if it is possible to activate/desactivate the "slide 开发者_如何学编程to unlock " event wich is normally activate/desactive through Settings->General->Passcode Lock

I'm almost certain that we could not play with those setting. I still want to know how we can do that. I suppose we have to use a private framework like some UIView animation, i want to know that for my personal use, it is not an AppStore app project

Thats not possible with the public API and an un-jailbroken device. and if your app does that, it will never be accepted to the appstore
