Swift 3.0 :

 func captureScreen() -> UIImage? {
    UIGraphicsBeginImageContextWithOptions(self.yourScrollViewName.bounds.size, true, UIScreen.main.scale)
    let offset:CGPoint = self.yourScrollViewName.contentOffset;
    UIGraphicsGetCurrentContext()!.translateBy(x: -offset.x, y: -offset.y);
    self.yourScrollViewName.layer.render(in: UIGraphicsGetCurrentContext()!)
    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return image
}

and use it as : let Image = captureScreen()
