title: How do you create a custom camera view, instead of UIImagePickerViewController?
body: <p>I created a simple application using UIImagePickerViewController for capturing from the camera, but I'd like to customize the interface for grabbing from the camera, such as adding some buttons.  </p>
  
  <p>UIImagePickerViewController doesn't allow this directly, so how would you create a custom view that allows for displaying the live camera feed and capturing from it?</p>
