Xcode 6: How to make an image view fill the screen on all devices? Auto layout not working?

Question

So I have an image view and a button. I need the image view to be the correct size (not look squished or stretched) on all devices and more importantly I need it to be the s

Answer 1

This is what worked for me:

View Mode:
Aspect Fill

As constraints for the image:
Align Center X to: Superview
Equal width to: Superview

The 'Equal width' property is the one that scale the image to the size of the screen.

If you want to have the button in a specific position, set constraints from it to the view, the main ones you want to consider are a top constraint and any left or right constraints. So you are telling the view where you want to position the button in relation to its sides.

Hope this helps.
