UIImageView in UIScrollView with Autolayout constraints appear messed up
I have a scrollview on a normal UIView. Set the correct constraints for it. Scrollview size is working fine when running the app. But the problem appears for the UIImageView in this scrollview.
I have added "typical" constraints to the UIImageView - trailing, leading, bottom space, and top space to 0 relative to UIScrollView. I also added Align Center X and Y to UIScrollView.
I have also set the contentMode to "AspectFit" to the UIImageView, but when I load a landscape oriented image, the image appears stretched following the UIImageView size (which fills up the UIScrollView).
How to fix this? Or do I need to remove the UIImageView constraints and manually setting the UIImageView size at runtime?

You must be missing something... For one, yourUIImageViewneeds Width and Height constraints. The leading/trailing/top/bottom constraints define the.contentSizeof the scroll view. Are you laying this out in IB? If so, when you set an image there, does it get "stretched" or does it correctly use the Aspect Fit mode?

Yes, am laying it out using storyboard IB. How do I set Width and Height constraints together with leading/trail/top/bottom? Won't that cause conflicts?

I'm assuming you are putting this image view inside a scroll view so you can Zoom? That is, you're not adding anything else (such as multiple image views to scroll left-right)?

@DonMag, yes there is just one scrollview and one imageview. It is like a single image viewer.
