title: Camera view as a subview in iOS
body: <p>I'll start with saying that I am new to objective-c and iOS-programming.</p>
  
  <p>What I want to do is to display camera as a part of a view, like a rectangle in the upper part of a screen, where should I start? </p>
  
  <p>(What GUI-component for the "camera view"? <code>AVCamCaptureManager</code> or <code>UIImagePickerController</code>?)</p>
