Is it possible to get a rendered image out of the contents from an UIView?

I need a kind of "screenshot" from everything that's displayed in an UIView. Maybe there's a way to just access the image data that the renderer generated to display the contents on screen?

The following should work. Depending on what sort of transforms you have defined on the view and layer you might need to apply some sort of rotation.

- (UIImage *)imageForView:(UIView *)view {
  UIGraphicsBeginImageContext(view.frame);
  [view.layer renderInContext: UIGraphicsGetCurrentContext()];
  UIImage *retval = UIGraphicsGetImageFromCurrentImageContext(void);
  UIGraphicsEndImageContext();

  return retval;
}
