title: iPhone: get image from camera without UIImagePickerController
body: <p>Please help me with my question.</p>
  
  <p>Is there any way to get image from camera without <code>UIImagePickerController</code>?</p>
  
  <p>I need to render current image(from camera) into image on my view and update it by timer.
  May be <code>AVCaptureStillImageOutput</code>? I didn't find any examples.</p>
  
  <p>Any ideas?</p>
