Question

Is it possible to automatically resize uiimage based on autolayout with aspect ratio (1:1)?

Btw I'm using collectionview as my view.

Here's my layout in storyboard

and here's the result when running the app

Answer 1

You have to add as in picture to make image sacrifice width to fit to aspect ratio constraint

Answer 2

If you want to have the UIImageView to always be a square and set the an aspect ratio on the width and height.

However if you want to resize the UIImage depending on the size of the imageView then in your custom UICollectionViewCell make the necessary adjustments in the layoutSubviews() . Here you can inspect the size of the UIImageView
