title: UIImagePickerController tutorial?
body: <p>I am currently developing an application and I need to be able when pressing a button to open the camera and take a snapshot that I will attach to a .json file and send to my server.
  I am searching on google and StackOverflow for the last couple of hours but all the tutorials seem very old (08'-09') or not match my needs. I know that all the work is done with <code>UIImagePickerController</code> class but I would like to have a working example. Does anyone know a good tutorial to get started for something like this?</p>
