How to expand camera view to full screen in swift - UIImagePickerController
<p>I am using UIImagePickerController to snap a photo with a pone and use that photo in the app later.</p>

<p>This is my code for starting a camera:</p>

<pre><code>imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = .Camera
imagePicker.showsCameraControls = false
imagePicker.cameraOverlayView = customViewTakePhoto()

presentViewController(imagePicker, animated: true, completion: nil)
</code></pre>

<p>It all works fine, the camera starts, I am able to fetch photo once it's taken, but there is only one thing I cannot figure out, and that is:</p>

<p>How to make camera view across the entire screen, before the photo is taken?</p>

<p>Here are the images showing exactly what I need</p>

<p>This is my View as it is right now (I highly recommend the book, btw):</p>
