How to prevent UIImageView from resizing with Autolayout

I'm recreating my UI with auto layout and have a navbar across the top and a 2x2 grid of UIImageViews filling the rest of the screen. I put in all the constraints so it maintains this arrangement in any orientation and it's working well when the UIImageViews don't have an image in them. When I programmatically load an image in the UIImageViews, they change size and placement even though I have constraints that should prevent this.

I have all the autoresizing masks off for everything and the UIImageViews set to Aspect fit.

This autolayout stuff is new to me, but I thought I had it working...until I put an image in there. Why would that change the size and placement of the UIImageViews?

Thanks for the help!

You can modify contraints at runtime if you link them with an outlet in your view controller.

For your case you would add a width and height constraint and link them to two outlets. Then after you know the image dimensions you would change the constant value.

I am describing this in detail for a similar use case I had here: http://www.cocoanetics.com/2012/11/first-good-auto-layout-use-case/
