How do I save the contents of a UIWebView as an image

问题

I want to save the content of UIWebView as an image. The code I have only saves the content of the webpage that is visible on the screen.

- (IBAction)saveImage:(id)sender
{
    UIGraphicsBeginImageContext(webCanvas.frame.size);
    [self.webCanvas.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *viewImage =UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    UIImageWriteToSavedPhotosAlbum(viewImage, nil,nil,nil);
}

I want it so it will save the whole webpage in the UIWebView including the part of the website that is not visible on screen. Is this possible?

You will need to check these:-

Hope this will help you.
