screenshot is not in proper size IOS

Question

In my IOS App Code I am taking screenshot of UIimageView but when I take it it's not taken properly by following code.

func captureView() -> UIImage {
//        let rect: CGRect = self.imageView.bounds

        UIGraphicsBeginImageContextWithOptions(imageView.bounds.size, false, 0.0)//add this line

        let context: CGContextRef = UIGraphicsGetCurrentContext()!
        self.view.layer.renderInContext(context)
        let img: UIImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return img
    }

I want the exect screen shot of the image in imageView because there are more images on it. Kindly suggest me proper code for getting exact UIImageView Screenshot

How about you add UIScreen.mainScreen().scale instead of 0.0 in UIGraphicsBeginImageContextWithOptions(bounds.size, false, UIScreen.mainScreen().scale)

func captureView() -> UIImage {
            UIGraphicsBeginImageContextWithOptions(bounds.size, false, UIScreen.mainScreen().scale)
            drawViewHierarchyInRect(bounds, afterScreenUpdates: true)
            let img = UIGraphicsGetImageFromCurrentImageContext()
            UIGraphicsEndImageContext()
            return img!
        }
