How to fill background image in subview in swift 4?

Question

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

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

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)

I have updated to UIImageView(frame: self.my_view_2.bounds). But it width is not adjust now – Enamul Haque Apr 17 '18 at 06:32
Is your `my_view_2`'s width is greater than view's width? – Ankit Jayaswal Apr 17 '18 at 06:34
@ Ankit Jayaswa No I have added constraints with main view width – Enamul Haque Apr 17 '18 at 06:36
@ Ankit Jayaswa that means constraint my_view_2 main view height & width – Enamul Haque Apr 17 '18 at 06:38
Update `autoresizingMask` with `[.flexibleHeight, .flexibleWidth]`. I have updated my answer as well – Ankit Jayaswal Apr 17 '18 at 06:39

Add this code in your viewDidLoad(). May be helps you to solve.

if #available(iOS 11.0, *) {
   scrollView.contentInsetAdjustmentBehavior = .never
} else {
   automaticallyAdjustsScrollViewInsets = false
}
