How to fill background image in subview in swift 4?

I have used scrollview. Over the Scrollview I have a UIView where I can set up my image as a background. But problem is that image height is not merged with UIView height. It is shown when scrolling bottom. I want add image with whole UIView. Here is my image screen shot

enter image description here

Here is my code

let backgroundImage = UIImageView(frame: UIScreen.main.bounds)
backgroundImage.clipsToBounds = true
backgroundImage.image = UIImage(named: "background_image")
backgroundImage.contentMode = .scaleToFill
self.my_view_2.insertSubview(backgroundImage, at:0)

Please Help me Thanks

Solution

  • Height of your UIImageView is same as screen size, if your view is greater than screen size, then white view will remain at bottom.

    let backgroundImage = UIImageView(frame: UIScreen.main.bounds)

    Update frame of backgroundImage with scroll's view, as:

    let backgroundImage = UIImageView(frame: self.my_view_2.bounds)
backgroundImage.autoresizingMask = [.flexibleHeight, .flexibleWidth] // In case if your my_view_2 frames increases
self.my_view_2.insertSubview(backgroundImage, at: 0)
