IOS SDK - how to screen shot content of tableView?

How to screen-shot ALL content of tableView? (all content = visible are + NOT visible area)

I tried this:

UIGraphicsBeginImageContext(self.tableView.bounds.size);
[self.tableView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage* image1 = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

self.imageView.image = image1;


but it doesn't work, I mean it's screenshot only visible area :(




I solved it :))

here is the code :)

+ (UIImage *)captureView:(UIScrollView *)view inContentRect:(CGRect)rect{
UIImage* image = nil;

CGPoint savedContentOffset = view.contentOffset;
CGRect savedFrame = view.frame;

UIGraphicsBeginImageContextWithOptions(view.contentSize, 1, 0);
view.contentOffset = CGPointZero;
view.frame = CGRectMake(0, 0, view.contentSize.width, view.contentSize.height);

[view.layer renderInContext: UIGraphicsGetCurrentContext()];
image = UIGraphicsGetImageFromCurrentImageContext();

view.contentOffset = savedContentOffset;
view.frame = savedFrame;

UIGraphicsEndImageContext();

// after all of this, crop image to needed size
return [Utils cropImage:image toRect:rect];
}
