title: How to open Settings programmatically like in Facebook app?
body: <p>I need to open Settings programmatically from within my app. I searched across SO but everywhere people say that it's impossible. But today I saw that it's implemented in Facebook app. There's a button on an <code>UIAlertView</code> and when you click it you open the Settings. So indeed this is possible to open Settings, I have witnessed this myself. But how to do that? Does anyone know how Facebook does that?</p>
