title: UIImage from AVCaptureMetadataOutput delegate (didOutputMetadataObjects)
body: <p>I am scanning QR Code &amp; Barcode using <code>AVCaptureMetadataOutput</code>. When then camera is focused to barcode <code>didOutputMetadataObjects</code> delegate is called and I am able to get barcode metadata string. But  I wonder how to get the scanned image(barcode image) from the <code>didOutputMetadataObjects</code> delegate .</p>
  
  <pre><code>- (void)captureOutput:(AVCaptureOutput *)captureOutput didOutputMetadataObjects:(NSArray *)metadataObjects fromConnection:(AVCaptureConnection *)connection{
  // How to get the scanned image from this delegate ?
  }
  </code></pre>
  
  <p>Thanks in advance..</p>
