How do I take a screenshot of a single view object instead of the entire screen?

So I have a UIImageView with some text overlayed on the top and bottom. I want to get a screenshot so I have a new image with the text overlayed on it. This is the code I was working with but I am unable to take a screenshot of the my UIImageView object properly.

func generateImage() -> UIImage
    // Render view to an image
        afterScreenUpdates: true)
    let memeImage: UIImage =

    return memeImage

Alternatively, I have also tried the code below, though the image saved is the right size/area of the screen, it ends up with blurry version of what I took a screenshot of:

    let context = UIGraphicsGetCurrentContext()

imageView.layer.renderInContext(context!) // tried drawInContext but it didn't work at all
let memeImage = UIGraphicsGetImageFromCurrentImageContext()

return memeImage


First, using UIGraphicsBeginImageContextWithOptions will allow you to adjust the scale factor to suit your screen size. Second, passing in the view you want to capture will ensure that you are working with the correct view/subviews.

func generateImage(currentView: UIView) -> UIImage {
        UIGraphicsBeginImageContextWithOptions(currentView.frame.size, true, 0.0)
        let memeImage = UIGraphicsGetImageFromCurrentImageContext()

        //UIImageWriteToSavedPhotosAlbum(memeImage, nil, nil, nil)

        return memeImage
