title: iphone, when saving image with "renderInContext" to device, the image is blurry?
body: <p>I'm using this code to render an image from view.
  Then i am saving it to photo album.
  The image is blurry?
  Why? Is there a solution?</p>
  
  <pre><code>UIGraphicsBeginImageContext(self.view.bounds.size);
  [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
  UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
  UIGraphicsEndImageContext();
  </code></pre>
  
  <p>Tnx all.</p>
