title: iOS: Coregraphics image poor quality
body: <p>I am not sure whether I can improve image quality but following code displays very poor image quality in PDF. I know its standard code to generate images from view but is there anything I could do to specify image quality or improve it?</p>
  
  <pre><code>- (void)renderView:(UIView*)view {
      UIGraphicsBeginImageContext(view.frame.size);
      [view.layer renderInContext:UIGraphicsGetCurrentContext()];
      UIImage *viewAsImage = UIGraphicsGetImageFromCurrentImageContext();
      UIGraphicsEndImageContext();
  
      [viewAsImage drawInRect:rect];
  }
  </code></pre>
