title: How to deal with new permissions/access requests?
body: <p>I'm trying to learn about how to deal with the permissions/access requests in iOS 6. Everything I've found so far just kind of describes this vaguely without presenting any code samples etc. Are there any good resources/tutorials for this?</p>
  
  <p>Specifically, I'm trying to discover whether there's a way to re-prompt the user programmatically to allow access to the address book etc. Or just general information on how to integrate this stuff into an app.</p>
